  • Treatment of metal slabs
    Patent number: 5150599
    Abstract: A pressing machine for reducing the width of a hot metal slab has a pair of platens which are caused to engage with opposite edges of the slab to apply forces which reduce the width of the slab. This pressing action may cause buckling of the slab and to prevent, or at least reduce, the buckling, one or both of the opposite faces of the slab has a restraint provided adjacent thereto. The restraint may be in two parts connected to respective platens and arranged to allow for movement of one platen with respect to the other platen.

  • Treatment of metal slabs
    Patent number: 5146781
    Abstract: A method of treating hot metal slabs (6) aims to reduce the width of the slab (6) produced by a continuous casting process to avoid the need for the prolific number of moulds otherwise required to produce slabs of various widths. In order to achieve this the hot metal slab (6) is presented, with its width dimension vertically oriented, to a pressing machine (24) having a vertically movable top platen (26) and a fixed bottom platen (28). The slab (6) is incrementally displaced, longitudinally, through the pressing machine and pressing forces are applied to its opposing edges by the platens, to reduce its width. Subsequently, the slab (6) is turned so that its width dimension is oriented horizontally and rolled between the horizontal rolls of a rolling mill (22). An apparatus for performing the method is disclosed.
