ABSTRACT:
To make it possible to not only improve yield ratio by eliminating loss of material but to also improve the productivity and quality accuracy of products, the hot rolling method of the present invention consists essentially of treating the rear end face of the preceding rolled material being rolled in the finishing mill and the front end face of the subsequent rolled material being rolled by the roughing-down mill in a way to be fit for welding, putting the front end face of the subsequent rolled material in contact with the rear end face of the preceding rolled material by setting the feed speed of the rolled material being rolled by the roughing-down mill faster than the feed speed of the preceding rolled material, pinching the contact faces of the two rolled materials from the top and bottom directions by means of a pressure welding mechanism, welding both rolled materials between the roughing-down mill and the finishing mill while performing resistance heating with the application of voltage under pressure with said pressure welding mechanism, and continuously rolling the welded rolled materials with the finishing mill to form them into steel sheets.
