A continuous casting plant () includes at least one continuous casting line, optionally, at least one reducing unit, at least one separation device, and one or more devices for tempering the strip, and at least one auxiliary rolling line is arranged parallel to the continuous casting line with conveyors (') for continuously inwardly transferring different slab formats into the line of the continuous casting plant ().

The invention relates to a method and a system for the production of hot-rolled strip silicon-alloy steel for further processing into grain-oriented sheets, such as electrical sheets, wherein a cast product, in this case a thin slab, for example, with a maximum thickness of 120 mm, is subjected to thermal pretreatment and to a subsequent rolling process on a hot-rolling line to set a desired recrystallization state. The invention proposes an intake temperature (T) of the cast product () into the hot-rolling line (or) of at least 1200&#xb0; C., and preferably in excess of 1250&#xb0; C., which should be controlled during pretreatment by adding at least one preheating stage () and one intensive heating stage () to ensure the final rolling temperature (T).
