Estimating the term…
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.

Casting and rolling plant for semi-endless rolling or endless rolling of a cast metal or steel strand (1a), which can be cut to length as required in the solidified state, wherein the cut lengths (20) of cast strand can be held at a high temperature and heated to rolling temperature and homogenized in a roller hearth furnace (2) and can then be fed into a rolling mill (3), and wherein the continuous casting machine (1) casts continuously, wherein a roller hearth furnace (2) that is designed with buffer length (23) and has at least one roller plane (24) is installed between the continuous casting machine (1) and the rolling mill (3) and at its inlet (12a) and/or outlet (12b) has a shearing station (14), which is followed by a descaling system (15), which is followed by the rolling mill (3), which is followed by a cutting station (16), a cooling station (17), and coilers (18).
