graphite electrode High power 650mm

1、Why does the quality of electrode joints play an important role in electric arc furnace steelmaking?   The joint plays a crucial role in the connection during electrode steelmaking. The quality of the joint directly affects the use of the electrode in electric furnace steelmaking. No matter how good the electrode quality is, if there is no high-quality joint to match it reasonably, problems will occur during steelmaking. According to relevant data, over 80% of electrode usage accidents in electric furnace steelmaking are caused by broken or loose joints. Therefore, choosing high-quality electrode joints is a guarantee for the normal use of electrodes in electric arc furnace steelmaking.   2. Which quality indicators of graphite electrode (joint) products have an impact on electric furnace steelmaking?   (1) Quality indicators of the electrode such as volume density, resistivity, strength, elastic modulus and coefficient of thermal expansion. (2) Quality indicators of the joint such…
