Improvement of steel ladle lining life with MgO-C and AI_2O_3-MgO-C Refractories

摘要

In an integrated steel plant, steel ladles are the major consumer of refractories. In SAIL plants average lining life of steel ladles in continuous casting shop varies from 60 to 90 heals depending upon the secondary processing units and ladle capacity. Higher steel ladle life is essential to increase ladle availability for higher production. During the last few years, steel ladle lining life has increased with the use of various qualities of magnesia carbon refractories m different zones of working lining. However, intermediate stoppages for mid term repairs are the major bottleneck to increase the availability of steel ladles.
