Hot-selling Electric Arc Furnace Electrodes - RP/HP/UHP Graphite electrode nipples 100% needle coke – Juchun

Graphite electrode joint is a crucial connection part in the use of graphite electrode. The joint plays a key role in the connection of electrode steelmaking. The quality of the joint is directly related to the use of electrode in electric steelmaking. The connection zone formed by the graphite electrode and the joint is the part with large and complicated electric, thermal and mechanical load, and also the part with common fracture. Graphite electrode joint should use needle coke as aggregate, coal asphalt as binder, through a series of technological processes including mixing, forming, roasting, impregnation, secondary roasting, re-impregnation, three times roasting, graphitization, mechanical processing, etc. to produce a high temperature resistant graphite conductive material.
