Abstract
A method and apparatus for rolling strip in line with a continuous caster is disclosed. A slab capable of being coiled say 1.5 inches or less, is passed through an in-line furnace to homogenize temperature and is thereafter coiled in one of two vertically aligned coilers in either side of the pass line. The slab is then payed off into a rolling mill while a subsequent slab is coiled in the other of the two coiler furnaces.
Claims4
A method of casting metal slabs and rolling said metal slabs into strip and/or sheet in line comprising the sequential steps of:
- (a) continuously casting a continuous steel slab having a thickness capable of being coiled;
- (b) equalizing the temperature of the forward section of said continuous slab to provide a substantially homogeneous temperature therein;
- (c) cutting off the forward section from said continuous slab to form an individual slab having the desired length;
- (d) coiling alternative individual slabs in a first coiler furnace and in a second coiler furnace vertically disposed relative to said first coiler furnace and located downstream of a continuous caster and upstream of a rolling mill;
- and
- (e) rolling each individual slab to strip by paying off said individual slab through said rolling mill from one of said vertically disposed coiler furnaces while taking up the following individual slab on the other of said vertically disposed coiler furnaces so that the speed of the continuous casting is coordinated with the rolling speed to provide a substantially uninterrupted method of continuous casting and rolling.
