Abstract
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° C., and preferably in excess of 1250° 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).
