Abstract

See full text

A method of tapping a steelmaking furnace comprised of determining a desired level of steel to be attained in a ladle, and calculating the weight of molten steel that will be present when the desired level is attained following a transfer of molten steel from the furnace to the ladle. The furnace is operated such that slag is formed on top of molten steel contained therein. The furnace is moved to a first position to cause transfer of molten steel to the ladle to begin. The transfer of molten steel from the furnace to the ladle is continued, and at the first occurrence of molten steel attaining the desired level in the ladle, molten steel attaining a maximum allowable weight in the ladle, or an excessive amount of slag being present upon the molten steel in the ladle, transfer of molten steel to the ladle is ceased.
