    Abstract: 一种带钢生产方法,其中钢水在连铸机中被铸造成板坯并利用铸造热量地使板坯穿过炉装置,随后在粗轧机中进行粗轧并在精轧机中被精轧成具有理想成品厚度的带钢,其中,在连续或半连续的过程中,a.对于铁素体轧制带钢的生产来说,板坯在粗轧机中在奥氏体区内被轧制且在奥氏体区轧制之后被冷却到钢基本上具有铁素体组织的温度,带钢、板坯或板坯的一部分在精轧机中以基本上对应于精轧机入口速度和随后的压下量的速度进行轧制,并且在至少一架精轧机机架中是在铁素体区中进行轧制的;b.对于奥氏体轧制带钢的生产来说,离开粗轧机的带钢被加热到或使其温度保持在奥氏体区内的温度上且它在精轧机中基本上是在奥氏体区内被轧制到成品厚度,随后带钢被冷却到处于铁素体区内的温度;将获得理想成品厚度后的铁素体轧制带钢或奥氏体轧制带钢剪切成随后卷取的具有理想长度的部分。

    Abstract: 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.

    Abstract: A cast carbon steel strip is prepared by continuously casting in a twin roll caster and cooling to transform the strip from austenite to ferrite at a temperature range between 400null C. and 850null C. at a cooling rate of not more than about 100null C./sec, such that the strip has a yield strength of greater than 450 MPa. The cast strip before cooling is passed through a hot rolling mill to reduce the thickness of strip by at least 15% and up to 50%.
