1450 ℃ silicon carbide electric heating element used in electrolytic aluminum industry
The silicon carbide electric heating element is a non-metallic high temperature electric heating element. It belongs to a minority industry in the carbide category, but it is widely used and is a necessary equipment in smelting, casting, new energy, military and other related fields. With the rapid development of aluminum industry, SiC elements are widely used in aluminum industry equipment. At present, SiC heating elements in aluminum industry are mainly used in holding furnace, annealing furnace, degassing box and other equipment. SiC heating element gradually replaces resistance wire heating.
