摘要： A process and device for producing a high-strength steel strip. In the process, liquid steel is cast in at least one continuous-casting machine (1) with one or more strands to form a slab and, utilizing the casting heat, is conveyed through a furnace device (7). The slab undergoes preliminary rolling in a preliminary rolling device (10) and, in a final rolling device (14), is finishing-rolled to form a steel strip with the desired final thickness. In a continuous, endless or semi-endless process, the slab undergoes preliminary rolling in, essentially, the austenitic range in the preliminary rolling device (10) and, in the final rolling device (14), is rolled in the austenitic range or, in at lest one stand of the final rolling device (14), is rolled in the two-phase austenitic-ferritic range, the austenitic or austenitic, ferritic rolled strip. After leaving the final rolling device (14), the strip is cooled rapidly to obtain the desired structure.

摘要： In the manufacture of hot-rolled steel strip, a continuous casting machine casts a slab and a roll stand for reducing the thickness of the slab to make strip is incorporated in line with the continuous casting machine. Advantages of simplicity and rolling quality are obtained when the roll stand is a two-high roll stand having a single pair of rolls. Where there is a reheater for reheating the strip after its rolling in the two-high roll-stand, the two-high roll stand is the sole apparatus for reducing the thickness of the slab after full solidification of the slab and prior to entry of the strip into the reheater.

摘要： A hot rolling installation should be constructed and able to be operated so that strips of materials, which can be shaped with different levels of difficulty and have a thickness of less than 1 mm, can be rolled. According to the invention, strip speeds of 15 m/sec should not be exceeded at the outlet of the last roll stand regardless of the material being used, and the hot-rolled strip should have austenitic structures. To this end, the invention provides that thin slab thicknesses of approximately 50 mm are used for easily shapeable material, that the first of seven stands is driven or executes only a smoothing pass, the slab is de-scaled in front of and behind the first stand, and that the second to seventh stand effects the reduction in thickness to less than 1 mm.
