Wear Resistant Castable Details
Wear-resistant castables are mainly composed of two phases: brown corundum, silicon carbide and other wear-resistant aggregates and ultra-fine powder. At the same time, sintering agents, ultra-fine powders, coating additives, ceramic powders, composite material powders, composite adhesives, etc. are added, and particles It is tightly packed, formed quickly, and has high strength. It can reach the design strength in three days, so there are no major macroscopic defects during use. The volume density is high, and its strength can reach more than 200Mpa at room temperature. The service life is more than 50 times that of ordinary concrete and refractory castables.
Wear-resistant castables are widely used in cement plants, coal-fired power plants, steel industry and petrochemical industry
1. From the air outlet of the vertical mill to the cyclone tube or dust collector air duct; bucket wheel machine barrel; ore and raw coal transportation silo and hopper; cyclone separator in the catalytic cracking unit
2. Vertical mill upper, middle and lower shell and bottom plate, belt conveyor hopper, trolley three-way bucket, receiving hopper, reactor
3. Wear-resistant straight pipes and elbows for conveying pulverized coal at the kiln head and kiln tail, gas cones, and sintering bed dust collection systems
4. High-temperature fan casing and air inlet and outlet ducts, circulating fluidized bed boiler combustion chamber, high-temperature cyclone separator, blast furnace feed chute
5. Circulation fan casing and air inlet and outlet ducts, boiler flue, blast furnace stone water quenching and furnace stone silo
6. Media grinding head feeding pipe and raw coal storage hopper, pulverized coal transportation pipeline and other parts with strong wear and erosion
7. Coal mill high-temperature fan casing and air inlet and outlet ducts, cinder and coal transportation pipelines
Semi-silica brick refers to an aluminum-silicon refractory product with a SiO2 content of greater than 65% and an Al2O3 content of 15% to 30%. They generally use clay containing quartz impurities or native kaolin refractory clay or tailings and pyroph...
The Al2O3 content of anchor bricks is above 55%, and some users require that the alumina content reach 75%, and the load softening temperature of 75% bricks reaches 1550C. However, in actual use, anchor bricks with high aluminum content cannot be enough. The key is Flexibility is the most important t...
