ABSTRACT
The design is a manufacturing workshop of hot rolling plate with a output of 220 thousand tons.Its product specifications range from 2.0×1600mm?used steels of carbon steel、alloyed stee. The design is refered to the 2250 Hot Rolling Strip Steel Plant of Liu Steel. The paper mainly includes the selection of raw material and subsidiary facilities and main facilities
formulation of produce technology?technology calculation of the typical production?proofreading the capacity of main fatuities including rollers and the electrical machinery. Setting about the products design it plans exactly the main economy norm of the workshop and its arrangement?environment protection and so on. Considering market prospect, the yield, product scheme, and metal balance of each kind of product are appropriately designed based on the annual plant capacity. For the typical product, the process flow diagram, depressing systerm, velocity system, temperature system, and crown systerm, etc. are determined. Furthermore, the production capacity of the rolling mill is checked, the economic and for this workshop is drafted.
