COATING METHOD AND APPARATUS FOR SELF-FLUXING ALLOY, AND CONTINUOUS CASTING MOLD USING THE SAME, AND MANUFACTURING METHOD FOR MOLD

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for inexpensively and firmly coating a copper plate with a self-fluxing alloy, and to obtain a continuous casting mold having a high wear resistance and a long life by using the copper plate coated by the above method and apparatus.

SOLUTION: The coating apparatus and the method are provided in which copper plate to be coated with the self-fluxing alloy is irradiated with laser and a self-fluxing alloy powder is continuously fed to the irradiated part. The coating layer is formed by irradiating the self-fluxing alloy with a laser beam having a wavelength of 630-940 nm, an energy density of at least 10 kW/cm2, and a heat input imparted to the coating part of 5-15 kJ/cm, and then by performing a remelting treatment. The continuous casting mold using the copper plate which is coated with the self-fluxing alloy with the use of the above apparatus and method is also provided.
