TAP HOLE STRUCTURE OF MELTING FURNACE AND METHOD OF REPAIRING SAME

摘要

In this tap hole structure of a melting furnace, a refractory brick sleeve is disposed in a tap hole part formed in a furnace wall brick. The sleeve is fixed by a stamp material filled in the gap between the sleeve and the tap hole part. This method of repairing the tap hole structure relates to a method for the tap hole the size of which is enlarged due to the wear of the first stamp material during tapping. In this method, the worn portion of the first stamp material is so linearly disassembled and removed from the outer surface side toward the inner surface side of the furnace wall as to form a linear disassembled surface, and thereafter, a second stamp material is filled and sealed in the gap between the linear disassembled surface and the first sleeve.
