The high purity graphite

A method to prevent the joints of the graphite electrode connected with the electric furnace. It is used to apply the graphitized connector billet to impregnation asphalt before it is processed into finished product. The best practice is to pre-process the graphite joint billet into a biconical conical shape similar to the shape of the connector, and then impregnate it. However, such as impregnation blank can also achieve the effect. The blank is directly processed into the electrode joint after the impregnation. Use the connector to the user. The invention can make the electrode not flabby when used by the user, and the electrode consumption can be reduced by 3-5%.
