<p>PROBLEM TO BE SOLVED: To provide a method and equipment for continuously rolling a metallic material, in which the stable operation of continuous rolling is executed and the manufacture of products having excellent quality of a joined part can be attained. SOLUTION: After a metallic rough shape material is successively rolled with a rolling mill train on the upstream side of a rolling line on which a plurality of rolling mill trains are arranged in series and after the shapes of an end faces of metallic base stocks are measured between the rolling mill trains on the upstream and the downstream sides with a joining device on which an image pickup unit for end-part shapes is mounted and which is preferably moved back and forth. The material is positioned by striking the rear end of a preceding metallic base stock against the tip of the succeeding metallic base stock, they are joined together after adjusting joining conditions in accordance with the measured value of the shape of the end face of the metallic base stock and, by continuously rolling the metallic base stocks with the rolling mill train, they are made into a metallic finished material.</p> |
