Claims (2)

1. Способ обработки жидкой стали шлаком, отличающийся тем, что для уменьшения затрат на выплавку шлака, снижения себестоимости и улучшения качества стали жидкий печной шлак после выпуска плавки и разливки стали из ковша переливается в другой ковш и повторно используется для обработки стали при выпуске последующей плавки, причем на жидкий шлак дополнительно присаживаются кокс в количестве 0,10-0,30 кг на тонну стали и известь до 0,5 кг на тонну стали при общем количестве печного шлака 2-4% от веса плавки.1. The method of processing liquid steel slag, characterized in that to reduce the cost of smelting slag, reduce production costs and improve the quality of steel liquid furnace slag after the release of melting and casting of steel from the ladle is poured into another ladle and reused for processing steel when releasing subsequent melting moreover, coke in an amount of 0.10-0.30 kg per ton of steel and lime up to 0.5 kg per ton of steel with a total amount of furnace slag of 2-4% of the weight of the smelting are additionally seated on liquid slag. 2. Способ обработки жидкой стали шлаком, отличающийся по п.1 тем, что жидкий шлак после выпуска плавки и разливки стали из ковша без перелива в другой ковш подается под плавку. 2. The method of processing liquid steel slag, characterized in claim 1 in that the liquid slag after the release of melting and casting of steel from the ladle without overflow into another ladle is supplied for melting.
