Abstract
In a continuous process for continuous casting and hot-rolling of metal sheet, off-line storage of a slab takes place in a thermally insulated storage chamber located alongside a thermally insulated zone through which the slab lengths travel in the production line between a cutter for the slab and the hot-rolling mill train. On stoppage of the hot-rolling mill train, at least one slab length is transferred laterally to the off-line thermally insulated storage chamber. To improve ductility, an induction heating stage is combined with a subsequent temperature-maintaining stage in the furnace for homogenization of temperature within the slab. Both these stages are performed on the slab at its casting thickness.
