Abstract

A method for producing a wide steel strip using thin slab continuous casting and rolling by the following steps a) casting a molten steel into a thin slab having a thickness of between 50 and 90 mm; b) cutting; c) soaking; d) heating by electromagnetic induction; e) descaling; f) rolling; g) cooling with laminar flow; and h) coiling. The method can effectively control the solution and precipitation of carbon, nitrogen, and sulfide in steel with a low cost. The process is easy and flexible, and steel can be produced in a wide range of categories. Further provided is a system for producing a wide steel strip with thin slab continuous casting and rolling.
