Abstract (en)

[origin: EP0872288A2] A long slab rolling process and apparatus for producing a plurality of coils from a single slab, comprises at least one continuous caster producing a cast metal slab, means to cut the slab into discrete lengths for rolling, a reheat furnace, a slab welder, an edger, rough and finish rolling mills to produce hot rolled metal strip, a runout cooling table to cool the hot rolled strip, a pair of pinch rolls and a pair of strip deflector tables to deflect the rolled strip downwardly from the rolling line and, in conjunction with a slowing of the speed of the second pinch roll, to form a loop of strip, a flying shear disposed downstream of the loop and adapted to cut the strip, a part of which is directed onto a first coiler and a remaining portion of which is directed onto a second coiler. In one embodiment of the invention, a second caster and cutter produces second cut slab lengths which are transferred to the reheating furnace after a slab length from the first caster has exited the furnace, and the head end of the second slab length is welded to the tail end of the first slab length. <IMAGE>
