Title:
METHOD FOR REMOVING METAL ON NOSE OF MELTING VESSEL FURNACE
Document Type and Number:
Japanese Patent JP2002332513
Kind Code:
A
Abstract:

To provide a method for removing metal on a nose of a melting vessel furnace in which a metal and slag adhered to and deposited on a nose part are removed by using oxygen-containing gas while suppressing damages of the refractory on a furnace bottom which are caused by molten metal left behind as much as possible.

After molten iron or molten steel is tapped from a melting vessel furnace 1, oxygen-containing gas is injected from a top-blow lance 7 while the slag 9 is retained in the furnace, and the metal 5 adhered to and deposited on the nose part is removed. Since the slag 9 is interposed between the metal and a refractory brick 3 on the furnace bottom, the molten metal 5 is prevented from being brought into contact with the refractory brick 3, and damages thereby can be suppressed.
