Silicon carbon rod is a rod-shaped, tubular non-metallic high-temperature electric heating element made of high-purity green hexagonal silicon carbide as the main raw material, processed according to a certain material ratio, and recrystallized and sintered by high-temperature siliconization at 2200 °C. The normal use temperature in the oxidizing atmosphere can reach 1450 °C, and the continuous use can reach 2000 hours.

Due to the high use temperature of silicon carbon rod, it has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, fast temperature rise, long life, small high temperature deformation, convenient installation and maintenance, and good chemical stability.

With the automatic electronic control system, an accurate constant temperature can be obtained, and the temperature can be automatically adjusted according to the curve according to the needs of the production process. Heating with silicon carbon rods is convenient, safe and reliable. Now it has been widely used in electronics, magnetic materials, powder metallurgy, ceramics, glass, ceramics, semiconductors, analytical testing, scientific research and other high-temperature fields, and has become an electric heating element for tunnel kilns, roller kilns, glass kilns, vacuum furnaces, muffle furnaces, smelting furnaces and various heating equipment.
