Graphite Electrode (SHP)

Semi-ultra-high power graphite electrode is a product between the high power graphite electrode and ultra-high power graphite electrode and it is just a folk name. There is no such a type of semi-ultra-high power in actual product categories. The semi-ultra-high power graphite electrode reduces the proportion of needle coke in the raw material ratio during smelting, thereby reducing the cost. It well applies to use in ultra-high power electric arc furnaces and refining furnaces.
