Abstract Cold rolled thin plate has many advantages, such as many varieties, high surface quality, good performance and wide application, etc。, and has gradually become an indispensable material in the field of production and construction in the national economy。 With the rapid development of the home appliance industry and the automobile industry, the quality and performance requirements of home appliances and automotive products are becoming more and more high。 Therefore, it is very necessary to design the workshop of cold rolling sheet steel strip。This  design reference to many documents and the actual material, selects the Q215 carbon structural steel as the raw material and carries on a series of cold rolling process design, The design contents include the introduction of cold rolling process, the development of metal balance sheet, the selection of equipment, the calculation of the rolling force calculation, equipment check and calculation of annual output。It also comprehensives technical and economic indicators and draws the shop floor plan。This article is devoted to the design of cold rolling of sheet steel, in order to achieve high quality, low consumption, high yield and environmental protection, and the future of the country's steel industry is full of hope。

Keywords：cold rolling sheet; process design; rules of reduction
