The basic characteristics of U-shaped silicon carbide rods: U - shaped silicon carbide rods are synthesized by two equal-radius silicon carbide rods with a common cold end. U -shaped silicon carbide rods can be connected to the power line at one end of the kiln . Mainly used in high temperature furnaces, furnaces with high requirements on the average temperature of the furnace, which are characterized by power saving and long furnace life.
The silicon carbide rod will react between the silicon carbide rod protection tube and many chemical substances volatilized from the burning material during the firing. If it reacts with some gases such as water, hydrogen, nitrogen, sulfur, halogen, etc. Alkali, salt, molten metal, and metal oxides will also react, corrode, or oxidize if they come into contact with each other. Therefore, it is very important to master the correct method of use, which often prolongs the service life of the silicon carbide rod, as well as its maximum heating temperature and height.
