A METHOD AND A SYSTEM FOR PRODUCING HOT-ROLLED STRIP SILICON STEEL BASED ON THIN SLABS |
摘要 |
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<SUB>in</SUB>) of the cast product (2) into the hot-rolling line (9a or 9b) 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 (3) and one intensive heating stage (6) to ensure the final rolling temperature (T<SUB>FR</SUB>). |
