MOLD COPPER SHEET FOR CONTINUOUS CASTING MANUFACTURING SAME

摘要

[PROBLEM] To provide a mold copper sheet for continuous casting having a high adhesion to the mold copper sheet base even when it is actually used for continuous casting and comprising a surface coating layer excellent in wear resistance. [MEANS FOR SOLVING THE PROBLEM] A metal layer of one or more kinds of metals selected from Ti, Cr, Ni, B, Si, and Al is formed as the innermost layer on the surface of a mold copper sheet base. Layers of a nitride or carbide of the metals of the metal layer or of a carbonitride and layers of the metals are alternated on the metal layer. A nitride, carbide, or carbonitride layer is formed as the outermost layer. The layers are preferably formed by PVD. At least the metal layer, the innermost layer, is desirably formed by using a bias voltage of the arc cut.
