Abstract
To provide a novel casting mold for use in continuous casting, which has long life and excellent heat resistance, yet capable of completely preventing corrosion, which frequently occurs on the lower portion of the casting mold.A continuous casting mold for steel made from copper or a copper alloy, wherein said casting mold comprises a plane in contact with molten steel partly or wholly covered with a tungsten alloy plating containing either or both of nickel and cobalt, and said plating containing tungsten carbide forming a solid solution therewith. To produce the casting mold above, there is used a plating solution containing either or both of a nickel salt and a cobalt salt and a tungstate, together with at least one selected from an oxycarboxylic acid and salts thereof, and at least one type of an organic compound and salts thereof having two or less of carbon atoms within the molecule, provided that its oxidation decomposition potential is lower than that of the oxycarboxylic acid or a salt thereof.
