300UHP GRAPHITE ELECTRODE
The 300UHP graphite electrode is an Ultra-high-power graphite electrode with a diameter of 300mm, the length and diameter can be processed according to customer requirements.
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.
