Abstract (en)

[origin: WO2007039483A1] Process and ultra-compact plant for the production of steel strip including a mold that produces a very thin slab, with narrow sides between 25 and 32 mm thick, and with a bulge, characterized by a core in which the steel is still liquid. The slab is passed at a speed of between 6 and 16 m/min through a vertical prerolling device that reduces the thickness of the slab and closes its liquid core. The slab is then pre-rolled and, forming a loop, assumes a horizontal position where it is descaled and undergoes reduction in a compact group of milllstands, maintaining its temperature above the recrystallization point Ar3.
