METHOD OF OUT-OF-FURNACE TREATING STEEL IN 100-T LADLE Russian patent published in 1997 - IPC

Abstract RU 2094482 C1

FIELD: steelmaking. SUBSTANCE: method consists in introducing ferroalloys into ladle, tapping metal and slag, balancing blowoff with neutral gas, ladle sampling, introducing ferroalloys correcting chemical analysis of metal, and final blowoff. According to invention, if thickness of slag layer in ladle is not larger than 200 mm and weight of ferroalloys introduced into ladle before tapping smelt is not higher than 700 kg, balancing blowoff is performed for 2 min and introducing ferroalloys correcting chemical analysis of metal and final blowoff are performed not earlier than when 70% of time metal being in ladle from the beginning of tapping to the beginning of casting is expired. EFFECT: enhanced efficiency of process. 1 tbl
