Method and apparatus for continuous casting and hot-rolling

摘要

In a continuous process for continuous casting and hot-rolling of metal sheet, off-line storage of a slab (17) takes place in a thermally insulated storage chamber (13) located alongside a thermally insulated zone (3) through which the slab lengths travel in the production line between cutting means (2) for the slab and the hot-rolling mill train (4). 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 (20) is combined with a subsequent temperature-maintaining stage in the furnace (3) for homogenization of temperature within the slab. Both these stages are performed on the slab at its casting thickness.
