设计年产量为280万吨的宽厚板厂

摘要：设计以包头地区为条件，设计年产量280万吨的3800mm宽厚板厂，分析

了在包头地区建造新的宽厚板厂的可行性和必要性。并结合设计条件及年产量要求完成10个产品规格的产品方案编制和金属平衡表编制。

本设计用连铸板坯轧制3800宽厚板，典型产品为Q235船板钢，规格为10mm×3800mm，30mm×3800mm。薄规格占年产量的15%，并以产品方案为对象进行了轧机布置形式、机架以及工艺流程的确定，以典型产品为对象进行了轧制规程、温度制度、速度制度、轧制压力以及轧制力矩的计算。对轧辊强度和轧机主电机能力进行了校核，选择了主要设备和辅助设备，并进行了各设备性能参数的确定，轧钢机的生产能力和年产量的计算均满足了设计要求。根据设计计算结果完成了车间平面布置图的绘制。

Abstract：Design in Baotou as the condition, the design of 3800mm heavy plate plant with an annual output of 2.8 billion tons, analysis of the construction of new heavy plate plant feasibility and necessity in the Baotou area. Combined with product development and metal balance table design conditions and production requires the completion of 10 product specifications.

The design of continuous casting slab rolling 3800 wide plate, typical products as Q235 steel, specifications for 10mm x 3800mm, 30mm x 3800mm. Thin accounted for 15% of annual output, And the mill layout, frame and determine the process to product scheme as the object, the rolling, temperature system, speed system, rolling force and rolling torque calculation based on the typical product as the object. On the strength of the roller and the rolling mill main motor ability is checked, select the main equipment and auxiliary equipment and the equipment, determine the performance parameters, calculation of rolling mill production capacity and annual output can meet the design requirements. According to the design calculation results completed drawing workshop layout. Key words: Heavy plate;plant design; production process; rolling
