PROBLEM TO BE SOLVED: To provide a coating method for continuous casting mold, which is free from the generation of thermal deformation, and is excellent in wear resistance and adhesion property. SOLUTION: Self-fluxing alloy or a coating material obtained by mixing the self-fluxing alloy with a carbide is thermally sprayed or powder layered on the inner wall surface of the continuous casting mold. The coating material is irradiated with a laser beam having a wavelength of 630 to 940 nm, energy density of at least 10 kW/cm<SP>2</SP>and is subjected to a remelting treatment to form a coating layer. Preferably, the shape of the surface irradiated with the laser light is rectangular with the short side of 0.1 to 1.0 mm and the long side of 4 to 20 mm or elliptic. COPYRIGHT: (C)2004,JPO
