HP 500mm graphite electrodes are very common in practice. There is a great demand in the world market. They are fit for electrical arc furnace, laddle furnace, and submerged arc furnace.
The loss of graphite electrodes in electric furnace steelmaking is very common, what are they and what is it related to? The following description is for your reference.
Physical loss
The physical loss of the electrode mainly refers to the end consumption and side consumption of the electrode, which is mainly caused by mechanical external force and electromagnetic force. It is concluded as follows
Looseness and breakage at the joint, cracking of the electrode and part of the thread of the joint falling off, which is caused by poor quality of the electrode itself,
In terms of equipment, improper electrode diameter selection, poor electrode holder, lifting and control devices;In terms of operation, large pieces of scrap collapses, hitting the electrode and poor connection between two electrodes
Chemical loss
Mainly refers to the consumption of the electrode surface, including the consumption of the electrode end and side. Generally speaking, the end consumption can reach 50% of the total electrode consumption, and the side consumption is about 40%. The larger the contact area between the electrode and the air, the greater the intensity of the oxidation reaction, and the consumption will increase accordingly.
