Advanced insulation material ceramic fiber blanket that used for industrial furnace
Ceramic fiber blanket, also known as aluminum silicate fiber blanket. Because one of the main components is alumina, and alumina is the main component of ceramic, so it is called ceramic fiber blanket. Ceramic fiber blanket is made by special aluminum silicate ceramic fiber filament with a special double-sided acupuncture process. Double-sided acupuncture process greatly improved the degree of fiber interwoven, tensile strength and surface roughness. Fiber blanket does not contain any organic binder, that is to make sure the ceramic fiber blanket have good stability at high temperature or low temperature.

Ceramic fiber blanket, with white color, regular size, does not contain any binding agent, and the refractory temperature is 950-1400 Degrees Celsius. It has low thermal conductivity, low heat capacity, excellent chemical stability, thermal shock resistance, tensile strength, and sound absorption. In neutral, oxidizing atmosphere, ceramic fiber blanket still could maintain good tensile strength, toughness and refractory fiber board structure after long-term use, is an excellent Insulating material.

Ceramic fiber blanket can be used in aerospace, steel, petrochemical high temperature insulation; military equipment fire insulation; industrial kiln, heating device wall lining insulation; high temperature equipment insulation; high temperature pipe insulation; electrical components thermal resistance; raw material of gasket; module, folding block.

Characteristics and Application of Refractory Castables with High Aluminum and Low Cement Content

Low Cement Castable
Low cement castable can be widely used for those industrial furnace's working lining, permanent lining( working temperature under 1400c), such as little refining Ladle cover, Ladle & Tundish permanent layer, heating furnace working wall, top and bottom. Blast furnace body, Hot metal ladle permanent layer.
The traditional refractories castable is made of refractory aggregate and high alumina cement. During the preparation process, the particle gradation of the fine aggregate fraction was not well designed. Cement particles are also coarse (specific surface area is generally 3000cm2 / g or so), the amount of cement is generally 15 to 25 percent, and the construction water consumption is 10 to 15 percent. Coupled with the amount of cement and more coarse particles, so that the cement can not be fully hydrated, resulting in poor performance of castables.

Low cement castable refractory castable is to overcome the shortcomings of the traditional refractory castable, the use of lower cement content, ultrafine powder technology, the correct design of aggregates push collection, and the use of highly efficient surface-active additives and other comprehensive technical measures prepared from, With the traditional refractory material pouring

High solidification rate, good volume stability, after drying and calcination, the volume shrinkage is small "and so on. It has the characteristics of low cement content, high compactness and low porosity, high normal temperature curing strength, good volume stability.

"GJ-180 high-strength refractory company castable" is based on fused white fused alumina as aggregate with pure calcium aluminate cement as the binder made of. The highest temperature of use of this casting material to 1800 ℃, 1400 ℃ under the hot state of the flexural strength of 7.4MPa, at high temperatures also has a good Wear resistance. It is suitable for the new kiln dry kiln cement kiln, three-channel coal nozzle and other parts used.

"GJ-18S castable" is fused white corundum as aggregate, it is a low cement content of refractory castable, the castable has a high mechanical strength and erosion resistance, erosion resistance, the maximum temperature of 1600 ℃ , Depending on its performance, this castable is suitable 1000 ~ 1400 ℃, the impact of serious wear and tear of large cement kiln mouth, multi-cylinder cooler elbow and other parts used.

"LC-160 castable" is a low-cement refractory castable, is based on high alumina bauxite clinker aggregate, pure calcium aluminate cement as a binder prepared, suitable for small and medium-sized dry kiln cement kiln mouth, Cooler elbow parts apply.

"GJ-15B (or GJ-15A) castable" commonly known as alkali-resistant high-alumina low-cement refractory castable, refractory brick for sale, it is through the matrix composition of the adjustment and control of preparation, with high mechanical strength, alkali corrosion, Temperature of 1500 ° C, suitable for cement production

The original, the fuel contains alkali, sulfur, chlorine high number of large dry kiln.

Precautions and repair measures of masonry refractory concrete precast block

Masonry refractories concrete prefabricated block must pay attention to the following matters:
1) refractory concrete prefabricated blocks of brick masonry joints for the 5mm ~ 10mm.
2) Masonry mud used should be consistent with the pre-block material.
3) masonry should be on the bottom surface of the prefabricated block on the surface of pulp, and then re-line. When hanging, should also be in the corresponding side of the pulp.
4) After the completion of each layer of prefabricated blocks, fill the joints in the refractory brick concrete.
5) cut off the ring, tie or fill in the vicinity of mud.
6) dome arch, the arch should try to tighten the sides.
7) masonry prefabricated block, such as the gap is too large, can be used in place of cast-in-place refractory castable concrete or fire brick plug.
silica ramming mass concrete repair methods:
  1) crack repair lining lining cracks, may not repair. But the emergence of thick cracks, cracks should be looking at the location, analysis of whether the impact on the lining life, can not form a large peeling. Where important parts, must be repaired.
Repair, first with water to wet. Usually in the thick stitch filled with homogeneous refractory material concrete, tapping formation. If the seam can be repaired into V-shaped re-repair, the effect is better. If a large slit appears in the lining, two slightly larger round holes can be cut at the two ends of the seam

, Re-block, so to prevent the spread of further expansion of the crack.
  2) peeling patching repair, should first clean up the peeling, sprinkle some water, and then the preparation of good homogeneous refractory concrete fill. Be careful when patching tightly wiping light. Repair to pay attention to the oven, the time is about 12h, then you can put into use.

Steel fiber reinforced low cement refractory castable

A heat-resistant steel fiber of a certain size is added to a castable refractories in a mixture consisting of a refractory material aggregate, a binder and an admixture to become

a steel fiber reinforced refractory castable. Compared with castables without heat-resistant steel fireclay refractories, the castable has the following characteristics:
1, can inhibit castable in the curing, baking and high temperature use in the contraction;
2, to improve the toughness of castable, anti-mechanical impact and mechanical strength;
3, to improve the thermal shock resistance of castable;
4, to prevent the cast material generated within the micro-cracks in the thermal stress and mechanical stress under the expansion or extension caused by the occurrence of fracture or peeling.
