550UHP GRAPHITE ELECTRODE
550UHP GRAPHITE ELECTRODE is Electrode with diameter of 550mm.Ultra-high-power graphite electrode(UHP) is processed by pressing, roasting, impregnating and graphitizing processes with high-quality petroleum coke, asphalt, and imported needle coke. It has high flexural strength, good seismic performance, and small consumption. It is widely used in electric arc furnaces of steel company, and silicon company and so on.
Compared with HP and RP electrodes, UHP graphite electrodes have more advantages as follows:
*Lower electrical resistivity, the lower the resistivity, the better the conductivity and consumption
*Heat tolerance and oxidation resistance, reducing physical and chemical loss in practice, especially at high temperature in practice.
*Smaller coefficient of thermal expansion,the lower the coefficient, the stronger the thermal stability of the product and the higher the oxidation resistance.
*Low ash content, which will get oxidation resistance improved much.
