New type of high alumina brick lead smelting furnace in different parts of which use

Lead smelting of lead sulfide concentrate, usually contain a certain amount of Zn, in the smelting process is also the oxidation of ZnS, while part of the reduction, part of the re-oxidation into the lead-rich slag, part of the form of steam into the flue gas, With the flue gas rising again in the process of secondary air oxidation, or contact with other elements after oxidation, while the flue gas contains large amounts of SO2 gas and high oxygen partial pressure. In the melt contains a lot of PbO and metal Pb, along with other normal slag composition, that is, FeO, CaO, SiO2, Fe3O4 and other impurities.

Melt a large number of PbO and Pb are low melting point material, in the 1000-1150 ℃ melting temperature, have good mobility and penetration, it is easy to penetrate into the cracks within the refractory brick. Pb infiltration into the brick body gap, the oxygen is oxidized into PbO, the volume will increase about 20%, which will greatly fill the gap of high alumina brick.

In addition, during the use of high-alumina bricks, the melt penetrates into the high-alumina bricks along the capillary channels such as pores and cracks, and interacts with it to form a metamorphic layer different from the original Clay, High Alumina insulating bricks. When the furnace temperature Fluctuations, the metamorphic layer will crack, peeling, melt deeper into the brick, the thicker the metamorphic layer, the thicker peeling structure. If the local oxygen potential in the furnace is high, it is easy to reoxidize the Cr2O3 in the local high alumina brick, and Cr3 + is oxidized to cr6 +, so that PbO reacts with CrO3 due to the strong basicity, and low PbO · CrO3 is formed, Anti - scouring performance of Bottom Frame &Skid Platform Brick for Heating Furnace.

At the same time, and the formation of high alumina brick Cr2O3 and other substances are a lso low melting point material, is not conducive to the formation of high melting point solid phase material. ZN vapor in the flue gas, if combined with Fe2O3 in the high-alumina refractory brick for sale, is reduced to a low-melting FeO phase and Zn is oxidized to ZnO, the volume of ZnO will be expanded by 5-6 times, In the infiltration of parts of the expansion effect. SO2 components within the flue gas, etc. on the composition of high alumina brick also has a certain chemical effect.

The characteristics of these slag and flue gas characteristics of high-alumina smelting furnace metallurgical furnace use has special requirements.

Refractory brick and clay fire brick distinction

refractory brick and fireclay refractories distinction
Clay refractory bricks are a kind of refractory bricks, the precise definition of refractory products are shaped, from the delivery form of distinction is a series of refractories.

Refractories are divided into ordinary refractories (1580 ~ 1770 ℃), advanced refractories (1770 ~ 2000 ℃) and special refractories (2000 ℃ above); according to the chemical characteristics of acid refractories, Neutral refractories and refractories. In addition, there are special occasions for the refractory material.

Now the definition of refractory, has not only depends on whether the refractoriness of 1580 ℃ or more. refractory brick for sale refers to the current application of metallurgical, petrochemical, cement, ceramics and other production equipment lining the inorganic non-metallic materials.

Acid refractories to silicon oxide (SiO2) as the main component, commonly used silica brick and clay brick. Silica brick is more than 93% SiO2 silica products, the use of raw materials are silica, waste silica brick. Silica brick acid-resistant slag erosion ability, but susceptible to the erosion of slag, and its load softening temperature is high, close to its refractoriness, after repeated calcination volume does not shrink, or even a slight expansion, but the thermal shock resistance is poor. Silica brick is mainly used for coke oven, glass furnace, acid furnace and other thermal equipment, silica brick in accordance with the SiO2 content and physical and chemical indicators can be divided into several levels, mainly divided into glass kiln silica brick and coke oven silicon Brick two categories. Clay brick or refractory clay clinker as the main raw material, containing 30% to 46% of alumina, refractoriness 1580 ~ 1770 ℃, is a weak acid refractory, good thermal shock resistance, acid slag corrosion resistance , Widely used in clay bricks to refractory clay as the main raw material is called ordinary clay bricks to coke gem clinker as the main raw material made of porosity was 17% below the clay brick known as low porosity clay brick. Two kinds of clay brick and according to which the physical and chemical indicators are divided into several grades, ordinary clay brick and low porosity clay brick between the price difference.

Neutral refractories to alumina, chromium oxide, silicon carbide or carbon as the main component. Neutral Refractory company in the main products are: corundum bricks, high alumina bricks, silicon Mo brick, mullite bricks, aluminum chrome bricks, aluminum carbon brick, graphite or carbon brick. High alumina products in the main crystalline phase is mullite and corundum, corundum content increases with increasing alumina content, alumina containing 95% of the corundum products is a wide range of high-quality refractory material containing alumina 95% of the corundum products is a wider use of high-quality refractories. The chrome brick with chromium oxide as the main component has good corrosion resistance to steel slag, but the thermal shock resistance is poor and the softening degree is low. High alumina bricks of the indicators are relatively good, with good cost-effective, so widely used, but because of high alumina brick erosion resistance is poor, it can not be applied to the key conditions of complex conditions, silicon brick is the use of aluminum Bauxite and silicon carbide as the main raw materials, mainly used in the transition zone of cement rotary kiln.

Carbon refractories are carbon brick, graphite products and silicon carbide products. Carbon products is another kind of neutral refractory material, which is divided into three categories: carbon brick, graphite product and silicon carbide based on the composition of carbonaceous material and the mineral composition of products. Carbon brick is a high-grade petroleum coke as raw material, plus tar, asphalt binder, at 1300 ℃ isolated from the firing of air conditions. Graphite products (except natural graphite) with carbonaceous materials in the electric furnace in 2500 ~ 2800 ° C in the graphite system in the system. Silicon carbide products are silicon carbide as raw materials, plus clay, silica and other binder in 1350 ~ 1400 ℃ firing. Silicon carbide plus silicon powder can also be made in the electric furnace nitrogen atmosphere under silicon nitride - silicon carbide products. Carbon products, low thermal expansion coefficient, high thermal conductivity, good thermal shock resistance, high temperature strength. Long-term use at high temperatures do not soften, from any acid erosion, a good salt resistance, not by the metal and slag wetting, light weight, high-quality high-temperature materials. Disadvantage is easily oxidized at high temperatures, should not be used in the oxidizing atmosphere. Carbon products are widely used in high-temperature furnace lining (bottom, hearth, lower furnace, etc.), melting non-ferrous metal furnace lining. Graphite products can do the reaction tank and petrochemical autoclave lining. Silicon carbide and graphite products can also be made of melting copper alloy and light alloy crucible. Carbon brick and graphite products, the main component of carbon (C), the thermal expansion coefficient is very low, high thermal conductivity, good thermal shock resistance, high temperature strength, acid and salt erosion, especially weak acid has good resistance , Free from metal and slag wetting, light, generally used in iron and steel smelting industry, but also for petroleum, chemical industry, autoclave lining. Silicon carbide is an excellent refractory, good corrosion resistance, but at high temperatures (more than 1400 degrees) is easy to oxidize, not suitable for use in the oxidizing atmosphere.

The main refractory products are magnesia and oxygen. The main products include magnesia brick, magnesia-chrome brick, Spinel brick and so on. Magnesia (MgO) more than 80% of the fire brick called magnesium bricks, according to the index can be divided into many grades of grades, magnesium bricks on the slag and iron slag has a good resistance, refractoriness than clay brick and silica brick high. Mainly used for open hearth, oxygen blowing converter, electric furnace, non-ferrous metal smelting equipment and glass industry and some high-temperature equipment. Magnesia-chrome brick on the resistance of the slag stronger, and the thermal shock stability is also much higher than the magnesium brick, so the application of more extensive, magnesia-chrome brick in the iron and steel smelting and non-ferrous metal smelting industry has almost replaced magnesium brick, Because of its chromium oxide (Cr2O3) can continue to spread, the magnesia-chrome brick can be easily linked to the kiln skin, so in the last 30 years, has been the first choice for cement kiln firing refractories, magnesia chrome brick Cr2O3 Will react with water, trivalent chromium can become hexavalent chromium, will cause pollution of water, is facing the trend of gradually withdraw from the cement industry market. Magnesia-alumina brick using magnesia and alumina as raw materials, compared with magnesia brick, its thermal shock stability and high temperature creep performance is better, use the site and almost the same as magnesium bricks. Dolomite brick and magnesium calcium brick performance is almost the same, dolomite brick to dolomite as raw materials, magnesium calcium bricks to synthetic magnesium calcium sand as raw materials, oxygen content is generally 15-30%, the remaining components are mainly magnesium oxide, with The role of purification of molten steel, generally only for the special steel smelting, magnesium calcium brick production process is more complex, easy to hydration and decomposition of water and steam, not easy to transport, the use of the process must be prepared to prevent work. Manganese iron spinel brick is a new product, mainly used for cement rotary kiln firing zone and transition zone, will be the cement industry alternative to magnesia chrome brick main products.

Refractory materials such as carbides, nitrides, borides, silicides and sulphides, such as alumina, lanthanum oxide, beryllium oxide, oxygen, zirconia and the like, are used in special applications. (Silicon carbide, titanium carbide, tantalum carbide, etc.), nitrides (boron nitride, silicon nitride and the like), borides (borides (borides), and the like); refractory materials having a melting point of 2050 to 3050C or higher; Zirconium, titanium boride, hafnium boride, etc.), silicides (such as molybdenum disilicide), and sulfides (thorium sulfide, cerium sulfide, etc.). Their melting point for the 2000 ~ 3887 ℃, of which the most refractory is the carbide. High temperature composites such as metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.

Special materials are often used AZS brick (ie, zirconia corundum brick), corundum brick, direct combination of magnesia-chrome brick, silicon carbide brick, silicon nitride bonded silicon carbide brick, nitride, silicide, sulfide, boride, carbonation And other non-oxide refractory materials; oxygen, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide, and other refractories. Commonly used insulation refractory products are diatomite, asbestos products, such as insulation boards. Refractory refractory materials are often used in refractory castables, refractory mud, refractory ramming material, refractory plastic, fill charge, refractory gunning materials, refractory materials, refractory coatings, lightweight refractory castable, gun mud and so on.

New requirements of second generation dry process cement for refractory

China's cement industry developed rapidly, the output from the early liberation of the development of 620,000 t in 2015 to 2.35 billion t, from 1985 onwards 31 consecutive years of production and consumption ranked first in the world, the new dry cement production technology and equipment level Has been close to the international advanced level, localization of equipment has been fully meet the needs of the cement industry. However, excess capacity of cement clinker in China, cement companies operating efficiency and low efficiency. Energy saving, reduce costs as a cement enterprise to enhance the economic benefits of the inevitable. China Building Materials Federation first proposed the cement industry should vigorously develop the "second-generation new dry cement technology", its purpose is to reduce the energy consumption of cement production and enhance business efficiency. refractory material as an indispensable lining process of cement sintering material, is the second generation of new dry process cement material support conditions. The second generation of new dry cement technology on the refractory materials put forward new requirements, and refractory configuration technology should also be compatible with.
Cement industry, the initial requirements of refractories materials to meet the protection of the metal shell of a single function; and the development of the second generation of new dry cement technology, requiring refractories with energy saving, green, longevity efficient, safe and stable and other functions .

Energy saving
The second generation of dry cement technology in the cement clinker heat consumption standards for the 650 cal  kg-1, and a large part of the calcination process of cement heat through the thermal radiation of the equipment surface dissipation. Therefore, the refractory company material as the basis of all high-temperature equipment lining material, should not only have good performance, but also should take into account the energy-saving insulation properties.
Green
The chromium content in the cement shall not be greater than 10.00 mg  kg-1. According to statistics, the water-soluble chromium (Ⅵ) in cement mainly comes from the fuel and raw materials of cement raw materials, crushing and grinding media, refractory materials (magnesia-chrome bricks) and chromium-containing wastes. For most cement companies, refractory high insulating brick (magnesia-chrome brick) is the most important source of water-soluble chromium (Ⅵ). Magnesia-chrome bricks because of good thermal shock resistance, high temperature resistance and hanging kiln skin capacity, is still the majority of domestic cement rotary kiln for the use of high-temperature zone. According to statistics, the domestic cement enterprises average per ton of cement clinker consumption of high-temperature zone with alkaline refractories of about 244 g, assuming that half of the bricks into soluble chromium (Ⅵ) and into the cement clinker, the cement clinker Soluble chromium (Ⅵ) content will reach 10.98mg  kg-1. Therefore, in the cement industry to eliminate the use of magnesia-chrome brick has been in the industry consensus, the major domestic basic refractories enterprises have developed alternative to magnesia-chrome brick refractory products used in high-quality, and in the country has been rapidly applied.
Longevity and high efficiency
New dry cement technology continues to move in the direction of large-scale development, the current Nissan 5000t and above cement clinker production line has become the minimum requirements of new projects of cement companies, Nissan 10000t or 1200t cement clinker production line in China has reached more than 10 articles. Large-scale cement production line requires the quality and stability of refractories alumina brick should be a corresponding substantial increase in long-life, high-performance refractories in the country to promote rapidly, the current domestic cement production line refractories have been slowly from the "overhaul a year "To" three years of two overhaul, "the goal of development.

Currently the most commonly used method of producing refractory balls

Machine pressure forming method is currently the most used in the production of refractories ball forming method. The method uses a pressure ball machine and a steel mold to press the prepared refractory material into a sphere. Because of the general machine pressure forming refers to the water content of 4% to 9% of the semi-dry material forming method, which is also called semi-dry forming. The method commonly used equipment friction brick press, lever press and hydraulic press and so on.
Machine pressure forming process is essentially a ball material within the particle-intensive and air discharge, the formation of dense sphere process. The ball-forming fire-resistant ball has the advantages of high density, high strength, small drying shrinkage and small shrinkage, easy control of fire-resistant ball size, so this method is the main part in refractory firebrick ball production. In order to obtain a dense sphere during press forming, sufficient pressure must be applied to the pellet. The size of the pressure should be able to overcome the internal friction between the pellet material, to overcome the external friction between the pellet and the mold wall to overcome the insulating castable moisture, particles and fill in the mold caused by uneven pressure distribution Uniformity.
The ratio between the three depends on the ball material dispersion, particle composition, ball material moisture, the size and shape of the sphere. Although the relationship between pressure and the densification of the sphere can be calculated by a number of theoretical formulas, such as the variation of the porosity of the sphere with pressure in logarithmic relation, the experimental method is usually used to determine the pressure per unit area of the sphere, Brick machine should have the total pressure.
Mechanical forming of the ball material requirements in addition to water should have a certain range of fluctuation, its particle size also has certain requirements, such as should have a reasonable grain size ratio, bulk density as large as possible. General critical particle size of 3 ~ 5mm, less than 0.088mm of fine powder content should be 35% to 45% range. The most common defects in machine-formed fire-resistant spheres are the crack and layer density. Spallation is the formation of pressure in the vertical direction of the pressurized layer of cracks. Ball material moisture is too high, too much powder, too little bonding agent and pressure will lead to the production of spall.
Therefore, in the production of these parameters must be controlled. Layer density phenomenon that the shape of the fireball after the density along the pressure direction of the inverter. By the above one-way pressurized insulating refractory cement ball is generally dense under the sparse, the same level is dense in the outer sparse. This is due to the friction between the pellet material and the ball material and the friction between the mold wall caused by the pressure decrease. Double-sided pressure and the wall in the mold coated with lubricating oil to reduce the external friction of the method can reduce this phenomenon and reduce the porosity of the sphere.
Selection of molding equipment should be based on the quality requirements of refractory balls, size and production volume for comprehensive consideration. General refractory ball with a simple fireball or shape, quantity, quality requirements of the general products, the choice of production efficiency of the high pressure ball machine; high quality requirements of the fireball can be nominal pressure not less than 2000K N friction Pressure ball machine.
