PURPOSE:To prolong the life of a mold considerably by covering the lower parts of the inside surfaces of the long side mold pieces of a mold for continuous casting provided with a pair of long side mold pieces and short side mold pieces and the parts of said surfaces in sliding contact with the short side mold pieces with protecting films. CONSTITUTION:A mold for continuous casting made of Cu or a Cu alloy is constituted of a pair of long side mold pieces 1, 1 and a pair of short side mold pieces 2, 2 which can change the width of slabs by sliding along the long side mold pieces. The lower parts 3 of the inside surfaces of the pieces 1, 1 and the parts of said inside surfaces in sliding contact with the pieces 2, 2 are coated with protecting films. The protecting films are applied after the base body of the mold is cut away by a required thickness. The preferable protecting materials are single layered plating films of Ni, Co, Ni-Fe, alloys of Ni or Co and P or B. |
