Abstract (en)
[origin: CA2687434A1] The invention relates to a process for producing strips (1) of silicon st eel, in particular of grain-oriented silicon steel, and also from multiphase steel, in which a slab (3) in initially cast in a casting machine (2), wher ein this slab is subsequently rolled to form the strip (1) in at least one r oll train (4, 5) and wherein the slab (3) is heated in at least one furnace (6, 7) upstream and/or downstream of the at least one roll train (4, 5). In order to improve the quality and producibility of grain-oriented silicon ste el or of multiphase steel, the invention provides that the slab (3) is heate d to a pre-roll temperature (T1) in a first furnace (6) downstream of the ca sting machine (2) and upstream of a pre-roll train (4), or the slab (3) pass es into the pre-roll train (4) using the casting heat without the presence o f the first furnace (6), that the slab (3) is then rolled in the pre-roll tr ain (4), that the slab is heated to a defined temperature (T2), which is hig her than the pre-roll temperature (T1), in a second furnace (7) downstream o f the pre-roll train (4), and that the slab (3) is then rolled to the final strip thickness in a finishing-roll train (5).
