Lining Silica Refractory , Si3N4 Silicon Carbide Refractories
Lining Silica Refractory , Si3N4 Silicon Carbide Refractories
Description:
Silicon NitriSi3N4 Bonded silicon carbide is silicon carbide,
metal silicon as the main raw material according to different requirements of manufacturers to produce various shapes of the adobe, after drying, in the nitrating furnace with high purity nitrogen reaction sintered. The product has a high temperature, high strength, volume stability and good thermal conductivity, acid, alkali and a variety of molten metal erosion ability and so on.
Applications:
The material is widely used in colored aluminum tank, zinc vertical tank; metallurgical industry, blast furnace lining, ceramic kiln shelf panels, pillars, separated flame plate; waste incineration furnace lining and other industries. Products, dimensions, physical and chemical indicators of useful life are up to customer requirements.
