imported needle coke

Ultra high power graphite electrode is made of high-quality low ash materials, like the petroleum coke, oil-based needle coke and coal pitch. After experiencing calcinations, burdening , kneading, forming, baking and pressure impregnation, it is graphitized in a high temperature of over 3000℃, And then treated with machining. 1. The various physical and chemical indicators of uhp electrode directly depend on the quality of the raw materials and the construction process of each link. The raw materials of our factory mainly come from PetroChina, Sinopec, as well as the United States and Japan.affected by the prices of bulk commodities such as oil and coal, the spot price of graphite electrodes also has certain volatility. 2. Imported Needle Coke Graphite Electrode is widely used for electric arc steel-making, yellow phosphorus, indusreial silicon, other alloys and non-metallic materials of electric atc furnace. 3. Uhp electrode is characterized by low resistivity, good electrical conductivity, low ash, even and compact structure, good antioxidation and high mechanical strength
