Silicon carbon rod (SiC) electric heating element is a rod-shaped non-metallic high-temperature electric heating element made of green high-purity hexagonal silicon carbide as the main raw material, processed by embryo, high temperature siliconization, and recrystallization at a high temperature of 2200 °C, and the surface temperature of the rod can reach 1450 °C. Silicon carbon rod texture is hard and brittle, small expansion coefficient, good resistance to cold and heat, not easy to deform, good chemical stability, strong acid resistance, and strong acid reaction.
The main advantages of silicon-carbon rod (SiC) electric heating elements are their high thermal radiation capability and precise temperature control. In industrial applications, it is usually processed into rods, strips, plates or U-shaped, etc., the use method is simple, can be paralleled, series, mixed use, can be installed horizontally or vertically, cost-effective, is the most commonly used electric heating element for medium and high temperature industrial electric furnaces and experimental electric furnaces.
The main advantages of silicon carbon rod is strong thermal radiation capacity, fast heating, strong oxidation resistance in hot state, etc., the purpose of silicon-carbon rod electric heating element heating on the electric heating supply channel is mainly to control or adjust the temperature of each section, so that the basin reaches the forming temperature, simply put, it is to control the cooling.
Silicon carbon rod has been widely used in electronics, magnetic materials, powder metallurgy, ceramics, glass, semiconductor, 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.
