White Fused Alumina (WFA) is obtained from the fusion of high purity calcined alumina in electric arc furnaces. WFA is raw material characterized with white color, high hardness, high density, low porosity, highly resistant to heat and abrasion, chemical stability, a high melting point, and large crystal size
Calcined Bauxite is produced by sintering high-alumina bauxite in rotary, round or shaft kilns at high temperatures. This process of calcining (heating) bauxite in kilns removes moisture and gives Calcined Bauxite its high alumina content and refractoriness, low iron, and grain hardness and toughness.
Fused Zirconia Mullite is made by the fusion of high-quality zirconia sand and industry alumina powder in the electric arc furnace. ln order to further increase the mullite chemical corrosion resistance, thermal shock resistance and reduce the coefficient of expansion, the introduction of ZrO2 in the Al2O3 –SiO2 system can improve the structure of mullite, to make it have good thermal shock resistance, erosion, abrasion resistance and other advantages.
As an alloy additive, Manganese Nitride is mainly used to smelt special alloy steel, high-strength steel, stainless steel, heat-resistant steel and other products, especially in large diameter steel pipes for transporting oil and natural gas and high-strength steel for manufacturing ships and automobiles. Nitrogen can improve the strength and plasticity of steel, expand the austenite zone, refine the grains and improve the workability.
Caustic Calcined Magnesite is made from raw magnesite, brucite and magnesium hydroxide re-extracted from seawater or brine by calcination in reverberatory furnaces, rotary kilns or boiling furnaces. It is light brown or white powder, odorless, tasteless and with high refractory insulation properties.
Fused Silica is made of high purity Quartz Sand by electrically fused in Electric Arc Furnaces, then the Crystalline Quartz Sand transformed into Amorphous Silicon Dioxide. Fused Silica has an extremely low coefficient of thermal expansion and a very low thermal conductivity, high resistance to thermal shock as well as excellent chemical stability.
As a new type of nitriding material, Ferro Chrome Nitride is commonly used as an alloy additive and is widely used in the smelting and production of nitrogen-containing stainless steel, corrosion-resistant steel, heat-resistant steel, alloy steel and other special steels. Nitrogen has the characteristics of promoting the formation of austenite.
