Main process of graphite electrode
The graphite electrode is made of petroleum coke and needle coke as an aggregate, and coal pitch is used as a binder, and kneading and molding are performed.
A high temperature resistant graphite conductive material produced by a series of processes such as molding, baking, dipping, graphitization and machining. Graphite electrodes are important high temperature conductive materials for electrical steel making. The graphite electrode is used to input electric energy to the electric furnace, and the high temperature generated by the arc between the electrode end and the electric charge is used as a heat source to melt the electric charge for steel making. Other ore furnaces that smelt materials such as yellow phosphorus, industrial silicon, and abrasives also use graphite electrodes as conductive materials. The excellent and special physical and chemical properties of graphite electrodes are also widely used in other industrial fields.
