Price of high temperature silicon carbide rod with equal diamete

Using green high-purity silicon carbide as the main raw material, the silicon carbide rod is made by processing, blank making, high-temperature silicification and recrystallization
It is a rod-shaped non-metallic high-temperature electric heating element
Domestic silicon carbide rod enterprises adopt the same formula and manufacturing process, and the service temperature can not exceed 1520 degrees
Compared with traditional electric heating wire and other metal components, this element has the characteristics of high service temperature, corrosion resistance, long service life, small deformation, many models, easy installation and simple maintenance
It is widely used in many high-temperature manufacturing fields such as magnetic materials, powder metallurgy, ceramics, glass, metallurgy, molds and so on
Due to environmental protection requirements, at present, the silicon carbide rod adopts a new hot and cold end manufacturing process, which has excellent hot and cold end resistance ratio, avoiding the damage to the furnace body caused by the high resistance temperature of the cold end of the silicon carbide rod manufactured and processed in the previous process
The resistance error of silicon carbide rods in the same batch shall be within & plusmn; 0
2 or so
If the heating of the silicon carbide rod in the furnace is uneven or local heating, it is necessary to consider replacing the silicon carbide rod in the whole furnace, which is conducive to improving the service life of the silicon carbide rod and prolonging the aging cycle of the silicon carbide rod resistance
The connection mode is related to the resistance of the silicon carbide rod
Generally, the connection mode at the beginning of the furnace is kept unchanged
When the number of silicon carbide rods replaced from the furnace reaches a certain number, because the manufacturer does not have resistance measuring equipment, the cold resistance can be simply measured with an instrument, and the components with small error in resistance value can be connected by changing the connection mode to continue to be used, When the output voltage of the control equipment cannot meet the operation of this batch of components, it indicates that the silicon carbide rod resistance has been aged and can not be used
