600 UHP graphite electrode
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.
