Do you know what is a hollow graphite electrode?
Hollow graphite electrodes are hollow electrodes. The preparation of this product is directly pressed into a hollow tube when the electrode is formed or drilled in the center of the electrode during processing. The other production processes are the same as the ordinary graphite electrode process. The production of hollow (hollow) graphite electrodes can save carbonaceous materials and reduce the weight of hoisting graphite electrodes; the hollow areas of the graphite electrodes can also be used to add alloy materials and other materials required for steelmaking or to pass the required gas. However, the hollow graphite electrode has a complicated forming process, limited raw material savings, and low production yield, so the hollow graphite electrode has not been widely used.
