Abstract: A device for fixing different-sized base area objects with a vacuum including on a table: first, second, and third vacuum chambers. The third chamber extending the first and second chambers to the entire x direction extension, and the second chamber having parallel, line-forming grooves in the x direction and connected to each other by a first connection channel in the y direction and being released/closed serially relative to the first chamber by a line-switching device. The third chamber includes parallel, column-forming grooves extending in the y direction and connected to each other via a second connection channel in the x direction and being released/closed serially relative to the first chamber by a column-switching device. The third chamber being released/closed serially in the y direction by the line-switching device, in a simultaneous, segmented manner according to the number and positions of the line-forming grooves in correspondence with the second chamber.

Abstract: 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.

Abstract: 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 (1a), which may be transversely separated as required after solidification. The casting strip part lengths (20) are fed to a roller furnace (2) for heating and equilibration at the rolling temperature and the partial lengths (20) for rolling out are fed to a rolling train (3) 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 (Vc) is reduced for a roller change such that between the end of rolling a preceding multiple length (21) and the insertion of a new partial length (20) or multiple lengths (21) into the rolling gear a sufficient buffer time for a roller exchange is provided.
