Petroleum Coke Is The Production Of Graphite Electrode

　　Petroleum coke is the main raw material for the production of various kinds of graphite electrode, graphite anode, graphite block, graphite products, as main raw material for production of prebaked anode, anode paste and other products. Characteristics of petroleum coke ash impurities is particularly low, and easy graphitization under high temperature, the graphite better quality.

　　Petroleum coke is one of the by-products of petroleum refining process. Crude oil and petroleum asphalt residue obtained after distillation and vacuum distillation (or cracking after the residue) can be used as coking feedstock. The main products are oil and gas, coking gasoline, diesel, the final residue is the petroleum coke.

　　An industrial technology is widely used as a mold processing field, EDM has always played an important role in. In the discharge process, in order to ensure the quality of mold, the selection of electrode is the key. Be in energy-saving, efficient manufacturing industry hot topic of the situation, on the selection of electrode, more and more customers choose graphite to replace the traditional copper for electrical discharge machining. In fact, the quality properties of graphite electrode with copper electrode does not have, improve the market competitiveness of enterprises and products, improve production efficiency, resulting in a substantial increase in cost reduction and profit. Persistent EDM electrode die than its high cutting speed and good performance.
