ABSTRACT:
In case that the surface of a mold for continuous casting of steel made of copper or copper alloy having at least partially nickel or nickel-base alloy plated thereon is injured, said surface is abraded without complete removal of said plated layer, the resulting exposed surface is dipped with concentrated strong acid for activation, and thereafter it is repaired by plating nickel or nickel-base alloy thereon.
