Abstract (en)
[origin: EP0461743A2] A hot roughing mill installation comprises one or two reversing roughing mills (4) through which a slab(s) of hot metal, in use, passes in a working direction (D). Upstream of the roughing mill(s) is a sizing press (2) which, in use, changes the width of the slab(s) after it has come out of a furnace (1) upstream of the sizing press (2). Downstream of the roughing mill(s) is a coil box (5) arranged to coil the roughed strip (P). Edgers (3), which form a thickened portion on each side of the slab(s), may be located immediately upstream and/or downstream of the or each roughing mill (4), and a rolling mill (6) may additionally be located between the sizing press (2) and the roughing mill(s). <IMAGE>
