Hot-rolled strip process maturity, cold-rolled production to provide a high-quality raw materials, greatly to meet the national production and living needs. The design is an annual output of 4 million tons of 1780 hot strip production line process design, product specifications thickness of 10.00mm. A slab of 230 mm x 1100 mm x 10000 mm was selected. Design based on annual production, combined with the market prospects of the products of a reasonable distribution of the production of products, product development programs and metal balance. In this paper, a series of rolling systems such as process flow chart, pressure system, speed system, temperature system and roll system were worked out. The production capacity of rolling mills was checked and the economic and technical indexes were calculated. A workshop floor plan. Finally, an Excel program for calculating the design parameters is attached. Steel coil diameter: φ762mm; coi
