Black Silicon Carbide Is Suitable For Refractory And Grinding Applications
Black Silicon Carbide is produced by fusion of quartz sand, anthracite and high-quality silica in electric resistance furnace. The SiC blocks with most compact crystal structure near the core are carefully selected out as raw materials. Through perfect acid and water washing after crushing, the carbon content reduced to the minimum and then the shining pure crystals are obtained. It is brittle and sharp, and has certain conductivity and thermal conductivity.

Semi-Friable Fused Alumina Widely Working On Heat Sensitive Steel, Alloy, Bearing Steel, Tool Steel, Cast Iron, Various Non-Ferrous Metals And Stainless Steel
Semi-Friable Fused Alumina is produced in electric arc furnace by controlling smelting process precisely and solidification slowly. The decreased TiO2 content and increased Al2O3 content provide the grains with medium toughness and hardness between white fused alumina and brown fused alumina, this is why it’s called semi-friable fused alumina. It has excellent self-sharpening property, which brings grinding tools made of it with high grinding efficiency, long service life, sharp grinding and not easy to burn workpiece.

Melt Drawn Heat Resistant Stainless Steel Fiber
The raw material is stainless steel ingots, using electric stoves which melt the stainless steel ingots to become 1500 ~ 1600 ℃ steel liquid, and then with a grooved high speed rotating melt-extracting steel wheel which produces wires that meets are our customers’ specific requirements. When melting down to a wheel steel liquid surface, the liquid steel blow out by slot with centrifugal force at extremely high speed with cooling forming. Melting wheels with water keep the cooling speed. This production method is more convenient and efficient in producing steel fibers of different materials and sizes.
