Silicon carbide tube is a high-quality silicon carbide product made of silicon carbide as the main raw material and sintered at high temperature. It has excellent properties such as high temperature resistance, corrosion resistance, fast thermal conductivity, high strength, high hardness, good wear resistance, good heat and shock resistance, large thermal conductivity and good oxidation resistance. The two ends are equipped with special high-temperature resistant insulation sleeves, which can effectively prevent the corrosion of metal solutions on electric heating elements (including silicon carbon rods, electric furnace wires, etc.). All indicators are better than various graphite products. It is mainly used in non-ferrous metal forging, medium-frequency casting, various heat treatment furnaces, metallurgy, chemical industry and other industries. Silicon carbide protective tube has excellent thermal conductivity, oxidation resistance, thermal shock resistance, high temperature wear resistance, good chemical stability, strong acid resistance, and no reaction with strong acids and alkalis.
