PURPOSE: To obtain a mold for continuous casting having large strength for base metal and excellent wear resistance at the inner face by forming the mold for high speed continuous casting by Cu-Be alloy, plating Ni-B alloy on its inner surface and further thermal-spraying and heat-treating Ni-base autogeneous alloy.

CONSTITUTION: The mold for continuous casting is produced by Cu-Be alloy containing 0.2W2.75wt% Be and Ni-B alloy containing 1.5wt% B is placed at 15μm thickness in the inner face of the mold. Next, by plasma thermal- spraying, the thermal-spraying layer of Ni-base autogeneous alloy composing of, by wt%, 17% Cr, 3.5% B, 3.0% Si, 0.7% c, 3% Fe, 0.5% Co, remaining part of Ni is formed. Further after keeping for about one hour in a heating furnace at about 1,000°C, the solution heat treatment is executed by rapid water cooling, and then the ageing treatment is executed at about 450°C for three hours.
