PROBLEM TO BE SOLVED: To provide a mold for edge press and a hot rolling method using it to form slab edges into a shape which hardly causes edge seam defects and performs edge press without causing creases near slab edges even if the edge press degree is intensified. SOLUTION: In the mold for edge press having inclined and flat portions at the input side, the protruded part is formed in the center of the pressing area in the slab thickness direction of an inclined portion and flat portions at the protruded and dented areas of the mold face. Only at the pressing area of the output flat portions at the dented area, the recessed caliber parts are formed to engaged with the upper and lower corners of the slab. Thus, the protruded shape and the shape of caliber part are specified. By using this mold for edge press, hot rolling is performed after edge press is used for stainless steel slab.
