Design of annual output of 1 million 500 thousand tons of cold rolled strip workshop

Abstract:Cold rolled strip has the characteristics of high surface quality, good performance, wide variety and wide application. Especially with the rapid development of the automotive industry and home appliance industry, the quality and performance requirements of the car and home appliances are also getting higher and higher. Therefore, it is necessary to develop the cold rolled strip. This design is a reference to the design of the 1700mm cold rolling plant, the annual output of 1 million 500 thousand tons, typical products for the DDQ deep cold rolled sheet steel strip, product specifications 0.35 x 1580mm.This workshop design mainly includes: continuous mill with pickling, cold rolling, annealing unit, hot dip galvanizing line, smooth units, shear machine, rewinding unit. Design products are ordinary steel, low carbon steel, ultra low carbon steel, low alloy high strength steel, silicon steel and so on. Products with the use of a wide range of specifications, precise thickness, small size deviation, smooth surface, good shape, stable performance and so on. Based on the above, the typical metal balance sheet and rolling schedule were established, and the rolling mill and motor ability were checked. The economic and technical indicators of the workshop are calculated, and the shop floor plan is drawn.

Key Words：Cold rolled strip; pickling and cold rolling mill; rolling schedule; rolling schedule; check
