Optimize and adjust the angle of the oxygen lance to avoid the direct effect of oxygen blowing on the electrode; optimize the use process of the oxygen lance and adjust the larger oxygen flow of the oxygen lance. The reasons for the fracture of electric furnace electrodes are divided into mechanical failure and electrical phase control.
Mechanical failure control is as follows: reasonable distribution. The distribution of various steels in the basket is reasonable to prevent the thin and light steel from forming a ball on the top of the furnace, which is difficult to go down, thus forming a large piece of scrap steel and shattering the pole; when melting, pay attention to the distribution of unmelted materials. For the generated bridge structure, by blowing oxygen or physically swinging, the charge will collapse at the position where the electrode is raised to avoid electrode fracture; the electrode installation should be reasonable and standardized to ensure stable clamping and installation; the electrode connection position is correct, and the electrode holder should be Above the connection location, and should not be caught on openings or rings.
