Abstract:This paper introduces two different layouts of twostands steckel mills, compares their advantage and disadvantage, and presents their scopes of application individually according to the different process requirement. The divided layout satisfies with different requirement of lessdeformable steels, during rough rolling to roll down the slab,during finish rolling to ensure the quality of products. It is very suited to producing stainless steel and special alloy steel. Otherwise, the tandem layout can reduce investment and will be beneficial to roll thin productions. It has advantage in producing carbon steel and low alloy steel. The paper can give a useful reference for other companies which are interested in building Steckel mill.
