Refractory for heating furnace

Refractory for heating furnace
Refractory for heating furnace
With the large-scale and high efficiency of the rolling mill, the heating furnace put forward higher demand, its development trend is large, low consumption, pollution-free and operational automation, building materials and therefore divided into side-open and lift Two kinds. The door is generally made of clay brick, refractory castable or refractory plastic, high aluminum insulation brick or refractory fiber mats and other materials for lining. Side open the door can use a furnace service, lift door due to temperature fluctuations and mechanical impact and other factors, the service life of about la. Out of the riveting with refractory material with the side of the billet heating furnace.
In addition to water-cooled cast iron out of the trough, the general use of high alumina brick or masonry masonry, the service life of 3 to 6 months. Sintered mullite or fused mullite large brick masonry, high strength, good wear resistance, but the thermal shock resistance is poor, easy to crack, its life around 1a. The use of heat-resistant steel fiber staggered corundum refractory castable in the field into the overall steel trough, the service life of more than 2a.
Ceramic chute with a small push-type refractory furnace, from the corundum a silicon carbide slide rails composed of ceramic slide. In the length of the furnace with a refractory brick masonry two or four rows of the wall. In the base wall masonry high alumina silicon carbide brick, and then install the sliding rail brick and composed of ceramic slide. Billet in the slide on the move to achieve the upper and lower sides of the heating, with less energy, billet without black and so on. Ceramic chute to withstand high temperature, billet load, high temperature wear and corrosion of iron oxide slag and other effects, the use of more demanding conditions, the life of about 1a. The bottom of the water cooling 'adiabatic refractory materials, large and medium-sized push silver or walking beam furnace, the bottom of the water cooling pipe is a vertical, horizontal distribution and support the role of thick-walled water cooling pipe composition. The purpose of adiabatic is to reduce the heat from the cooling medium, reduce the billet black print and improve the quality of heating.
The adiabatic way is divided into special-shaped clay brick mosaic or horseshoe-shaped brick hanging, refractory plastic or refractory castable made of welded tile prefabricated block welding or with the material and refractory fiber felt on-site dressing. Life is generally 3 to 12 months. When the use of high-quality refractory plastic, ultra-low cement or cement-free refractory castables for field dressing, the life of more than la. Flue and smoke for their own use refractory lase lining generally with dry clay masonry, can also be used refractory castable prefabricated block hanging or on-site watering, and sometimes can be used refractory spray coating construction. Red brick or concrete chimney in high temperature area with refractory masonry. Metal chimney wall welding metal anchor nails, sometimes with metal mesh, the use of lightweight refractory castable or refractory spray for lining, construction convenience, integrity, long service life. (Refresable for rehea-ting fumace) Refractory materials used in masonry furnaces and related parts. The furnace is used for rolling or forging steel. Heating billet or small steel ingot thermal equipment, the use of the temperature is generally 13 of a 1 40. ℃.
This type of furnace is generally made of refractory clay brick masonry, heating section and soaking section roof is also useful 3-high aluminum brick 'lining damage is mainly due to high temperature, thermal stress, air erosion and mechanical collision caused by the role of high temperature The lower part of the furnace wall, the bottom of the furnace and the water-cooled tube packing layer and other parts are also affected by the erosion of molten iron oxide slag, therefore, masonry or mattress magnets for the protective layer, water pipe dressing layer with high alumina refractory.

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.
