ABSTRACT:
A method of rebuilding the eroded area of an ingot mold such as used in casting steel ingots places a metal producing exothermic compound in a cleaned eroded area of the ingot mold to be rebuilt, ignites the compound and confines the molten metal produced by the exothermic reaction to the eroded area where it forms a welded bond with the metal of the ingot mold and fills the eroded area. A protective metal coating of a suitable welding rod metal may be deposited by electric arc or flame welding on the metal patch formed of the exothermic material.
