Ultrahigh-power graphite electrode contact and preparation process thereof
The invention discloses an ultrahigh-power graphite electrode joint and a preparation process thereof, belongs to the technical field of graphite electrode joints, and solves the technical problems oflow breaking strength, insufficient physicochemical indexes, low superior product rate and the like of the conventional ultrahigh-power graphite electrode joint. According to the technical scheme, the ultrahigh-power graphite electrode contact is prepared from the following raw materials in parts by weight: 45 parts of needle coke, 55 parts of calcined coke powder, 25 parts of asphalt binder and0.5 part of a Fe2O3 additive, wherein methylbenzaldehyde and p-toluenesulfonic acid are added into the asphalt binder. The process comprises the following steps: 1, burdening; 2, mixing and kneading to prepare paste; 3, performing extrusion molding; 4, performing primary roasting; 5, performing primary dipping; 6, performing secondary roasting; 7, carrying out secondary impregnation; 8, roasting for the third time; 9, performing graphitization treatment; and 10, machining. According to the invention, the volume density and breaking strength are improved, various physicochemical indexes are superior to those of the original product, and the production cost is greatly reduced.
