Butt end silicon carbide rods are often used in old-fashioned heat treatment furnaces, experimental furnaces, tunnel furnaces, etc. Function of silicon carbide rod: Because the silicon carbide rod adopts high temperature, it has the characteristics of high temperature resistance, chemical resistance, corrosion resistance, fast heating, long furnace age, small shape transformation at high temperature, and convenient installation and maintenance. It has good chemical stability. If it is matched with an automatic power supply system, it can not only obtain an accurate constant temperature, but also automatically adjust the temperature according to the actual demand of the production process according to the curve. It has been deeply used in coastal defense, machinery, smelting, lightening, porcelain, semiconductors, anatomical testing, scientific discussions, etc. Tunnel kilns, roller kilns, glass kilns, vacuum furnaces, muffle furnaces, metallurgical furnaces and various processing facilities, using silicon carbon processing is convenient, safe and reliable. It is deeply used in many high-temperature electric furnaces, electric kilns and electric cannon smelting facilities in industries such as electronics, magnetic materials, powder smelting, porcelain, glass, smelting and machinery.
