What are the consequences of serious oxidation at the electrode of the upper end of the gripper?
Measures to prevent oxidation in graphite electrode steelmaking
Scrap is burned in the furnace. At the same time, because of oxygen blowing, the flame column height is often higher than the electrode of the upper end of the gripper. It is easy to oxidize the electrode end surface. If the oxidation is serious, the deformation of the electrode end surface will change from plane to inclined surface. When the upper end is connected with the new electrode, the oxidation deformation of the lower electrode end surface will occur. The new electrode can not be well contacted, and the gap of the electrode is large, which can easily cause oxidation and fracture of the internal joints. Without changing steelmaking conditions, the best preventive measure is to install a protective cover on the electrode end of the upper end of the gripper to prevent flame and air, so as to achieve the purpose of protecting the electrode end.
