- the invention relates to a method for producing strips of steel, preferably of silicon steel, in particular of grain-oriented silicon steel, or of multi-phase steel or of a steel with comparatively high alloy contents (eg microalloyed steel), in which initially in a casting machine a slab is cast, which is then rolled in at least one rolling train to the strip and wherein before and / or behind the at least one rolling line is carried out a heating of the slab in at least one furnace. Furthermore, the invention relates to an apparatus for producing a strip of silicon steel and multiphase steel.
- Grain-oriented silicon steel is currently being rolled in conventional hot strip mills.

- the slab is then rolled in a roughing and finishing line to the thin hot strip finished.
- Multiphase steels are usually produced in conventional hot strip mills. Due to the temperature difference over the length when entering the finishing train, it must be accepted that the rolling speed changes over the length in order to set a constant final rolling temperature. The increasing speed along the length of the strip leads to difficulties in setting a homogeneous structure over the length in the cooling section, since multiphase steels must be subjected to complicated temperature-time cycles.
