<p><P>PROBLEM TO BE SOLVED: To provide a method for treating residue in a converter after tapping, with which the residual molten steel at the last refining time is not shifted to a slag ladle side as far as possible while removing the slag at the last refining time, and thus, a steel-making yield in the converter, that is, [1-(the charged iron source-tapping quantity)/(the charged iron source)], is improved. <P>SOLUTION: After cooling the residue in the furnace by charging a solid iron source as the cooling material to the residue in the furnace remaining in the converter after tapping, the remaining molten steel in the above residue in the furnace, is stuck and solidified to the furnace bottom and the furnace wall of the converter by swinging the furnace body of the converter while maintaining the remaining slag in the molten state and thereafter, the molten slag is discharged by tilting the converter. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
