Silicon carbide roller/beam
Vacuum reaction sintered silicon carbide (SISIC) roller, beam is a new ceramic material, with high temperature resistance, oxidation resistance, high strength, extremely cold and heat resistance, good thermal shock resistance, high temperature decreases, good thermal conductivity, wear resistance, corrosion resistance, etc. As energy-saving refractory material, it is widely used in high-temperature furnace of industries such as sanitary ceramics, porcelain, electric porcelain, magnetic materials, microcrystalline, powder metallurgy, steel heat treatment. The components made of it is increasingly used in power generation, paper making, petroleum, chemical, mechanical seals, pumps, surface treatment, heat exchanging, mineral processing, aerospace and other fields.
