METHOD OF REPAIRING DAMAGED INGOT MOLD HANDLING LUGS

摘要

METHOD OF REPAIRING DAMAGED INGOT MOLD HANDLING LUGS A method for repairing damaged ingot mold handling lugs wherein a refractory perimeter is placed around the damaged lug and sand is deposited against the undamaged surfaces of the existing lug so that a cavity is formed adjacent to the damaged surface of the lug. An aluminothermic reaction mixture is then placed within the perimeter and ignited causing molten metal to fill and solidify within the cavity. Finally, the refractory perimeter, sand and reaction product slag are removed, and the deposited metal shaped as desired.
