A method for semi-endless or endless rolling by casting a metal strand, especially a steel strand, which is cut to length as required after solidification, wherein the cut lengths of cast strand are fed into a roller hearth furnace for heating and homogenizing at rolling temperature and are then fed at rolling temperature into a rolling mill to be rolled out. The continuous casting is continued without interruption during the rolling operation, and a sufficient buffer time for a roll change is maintained in the rolling mill. For carrying out a roll change, the casting rate is reduced as a function of the feed rate of the rolling mill and/or the roll-changing time, and/or the buffer length of the roller hearth furnace, and/or the final rolled thickness after the strand has been cut to length.

Method and continuous casting and rolling plant for semi-endless or endless rolling by casting a metal strand, especially a steel strand, which is cut to length as required after solidification

The invention relates to a method and casting roller plant for the semi-endless or endless rolling by casting of a metal, in particular a steel strip (), which may be transversely separated as required after solidification. The casting strip part lengths () are fed to a roller furnace () for heating and equilibration at the rolling temperature and the partial lengths () for rolling out are fed to a rolling train () for rolling, whereby the strip casting is continued uninterrupted during the rolling operation. According to the invention, a closer matching of the strip casting and the rolling can be carried out, whereby the casting speed (V) is reduced for a roller change such that between the end of rolling a preceding multiple length () and the insertion of a new partial length () or multiple lengths () into the rolling gear a sufficient buffer time for a roller exchange is provided.
