Abstract (en)
[origin: CA2654913A1] 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 th in slab, for example, with a maximum thickness of 120 mm, is subjected to th ermal pretreatment and to a subsequent rolling process on a hot-rolling line to set a desired recrystallization state. The invention proposes an intake temperature (Tin) of the cast product (2) into the hot-rolling line (9a or 9 b) of at least 1200øC, and preferably in excess of 1250øC, which should be c ontrolled during pretreatment by adding at least one preheating stage (3) an d one intensive heating stage (6) to ensure the final rolling temperature (T FR).
