Abstract

A hot rolling method which, even if an abnormality occurs before, during or after the joining of metal pieces, does not need to stop the operation of the line. The method is such that if, at the inlet side of a finish rolling machine (26), the leading end of a following metal piece is to be joined to the trailing end (1OB) of a preceding metal piece so as to be subjected to finish hot rolling continuously with the preceding metal piece (10), it is decided whether or not endless rolling is possible before and after joining and if it is found impossible, joining is suspended and the following metal piece (12) is stopped so that after the trailing end (1OB) of the preceding metal piece has passed through the finish rolling machine (26), the following metal piece (12) is retransferred and finish-rolled with a setting for batch rolling, and if an abnormality occurs in the joined portion after the joining, the joined portion (11) is cut off between the joining device and the finish rolling machine (26), and the material to be rolled is fed into the finish rolling machine with a setting for batch rolling.
