Silicon Carbide Rod

Silicon carbide rod is a rod-shaped, tubular non-metal high-temperature electric heating element made of high-purity green hexagonal silicon carbide as the main raw material, processed according to a certain raw material ratio, and processed by high-temperature silicidation and recrystallization and sintering. It has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, fast heating, long life, small high temperature deformation, convenient installation and maintenance, and good physical and chemical stability. It has been widely used in national defense, machinery, metallurgy, light chemical industry, ceramics, semiconductors, analysis and testing, scientific research and other fields, and has become the electric heating element of various electric furnaces and electric kilns. For tunnel kilns, roller kilns, glass kilns, vacuum furnaces, muffle furnaces, smelting furnaces and various heating equipment, the use of silicon carbide rods for heating is convenient, safe and reliable.

Our silicon carbide electric heating element adopts new production technology, has excellent cold and hot end resistance ratio, high efficiency, energy saving, long life and other characteristics.
