The present invention relates to a hot rolling method of steel products and a hot rolling roll for steel products, both of which are effective in preventing steel products, particularly stainless steel products, from seizing between the rolls and the steel products to be rolled, preventing wear of the rolls, and preventing the deterioration of both the rolls and the steel products, when the steel products are subjected to hot rolling. The method for the hot rolling of steel products according to the present invention, comprises rolling steel products while forming a film of an oxalate (such as iron oxalate, calcium oxalate and the like) on the roll surfaces which have contact with the steel products to be rolled. In particular, the rolling is effected while cooling by using, for example, as a part or all of the roll cooling water, an aqueous oxalic acid solution or an aqueous solution containing a water-soluble oxalate, and an aqueous solution containing water-soluble calcium compound, and jetting these solutions against the rolls, during the course of hot rolling from nozzles in separate lines. In addition, the method for the hot rolling of steel products according to the present invention may be carried out by immersing rolls for hot rolling of steel products in an aqueous oxalic acid solution, or coating or spraying an aqueous oxalic acid solution on the roll surfaces which have contact with the steel products to be rolled, thereby, forming an iron oxalate film, and rolling the products with the iron oxalate-bearing rolls. The hot rolling rolls for steel products, according to the present invention, have an oxalate film on the roll surfaces which have contact with the steel products to be rolled. <IMAGE>
