Design Description Annualproduction of 2.6 million tons of thin slab continuous castingand rolling workshop process design
Abstract:This design introduces the development situation and future prospect about the thin slab continuous casting and rolling technology of steel industry. At the same time, it proposes systemic comparison and analysis for several typical thin slab continuous casting and rolling technology and selects FTSR process line as the main body of the design. This paper also focus on the instructions about the design process of the production workshop of FTSR thin slab continuous casting and rolling, including the choice of equipments, process parameters, the layout of production workshop, the valuation and other key issues. 16MnL is selected as a typical kind of steel. The main production thickness is 1.0 ~ 12.7 mm, width is 850 ~ 1680 mm. At last, it also works out a series of strength check of the designed equipments and makes reasonable distribution of the overall layout of the workshop equipments.
Key Words：Thin slab，Continuous casting and rolling，Process design，Workshop layout
