PROBLEM TO BE SOLVED: To provide a method for maintaining a side surface of a titanium slab, capable of improving a yield of a titanium material, by preventing seam scratches and fin cracks which are caused during hot rolling of the titanium slab, and to provide the maintained titanium slab for the hot rolling.SOLUTION: In a method for maintaining a side surface of a titanium slab, (1) the slab side surface of the titanium slab is ground by 0.7 mm or more, and thereafter a visually observed defect is removed by partial maintenance. It is desirable that grinding of the side surface of the slab is performed by an automatic grinder, and the partial maintenance is performed by a grinder. (2) The titanium slab is supplied for hot rolling. The side surface of the slab is ground by 0.7 mm or more, and thereafter the visually observed defect is removed by the partial maintenance. |
