Continuous steel casting is a process to obtain casting billets by the molten steel casted into the caster, solidifying, and cutting. It is a process between steelmaking and rolling, also called continuous casting for short. The steel billets produced by continuous casting are raw materials for various products in hot rolling mills.Web

Abstract. In continuous steel casting operations, heats of molten steel are alloyed and refined in ladles, continuously cast and cut into slabs, and hot-rolled into coils. We present a mixed-integer program that produces a daily casting schedule and that is solved using state-of-the-art software for a direct-charge steel mill; two casters ...Web
