| Abstract: | Slag basicity, foamed slag height, angle of blowing oxygen and reline mode are the main factors influencing lining service life of 20t EAF. In order to improve lining service life, measures such as controlling slag composition, arc-covering foamed slag operation, blowing oxygen, spraying and repairing lining are carried out, then the lining service life is more than 600 heats. |
