摘　　要：热轧带钢生产线工艺、设备的发展已相对成熟,但仍需要进一步优化改进。以典型热轧带钢生产线的加热炉选型和烧损控制、粗轧机组平轧机主电机转速确定、精轧机组厚度控制系统等为研究对象,通过分析炉型对产量的影响及氧化铁皮量和加热温度的关系,提出选择步进梁式加热炉的建议,以避免产能源头受限;通过对轧制程序表计算、负载模拟、不同转速的电机价格对比,介绍了如何确定更优的主电机转速;通过分析精轧机组不同厚度控制系统对产品厚度和精度、板形的影响,提出了厚度控制系统选取建议。对上述设备选型和参数确定优化后,可实现热轧带钢生产线产能释放、烧损降低,节能降耗和产品质量的提升。The process and equipment of hot rolled strip production line have been relatively mature,but still need to be further optimized and improved.The selection of reheating furnace and the control of burning loss in typical hot rolled strip production line,the determination of the main motor speed of the roughing mill and the thickness control system of the finishing mill are taken as the research objects.Through the analysis of the influence of the furnace type on the output and the relationship between the amount of iron oxide scale and the heating temperature,the suggestion of selecting the walking beam reheating furnace is put forward to avoid the limitation of the output source.Through the calculation of rolling schedule,load simulation and the price comparison of motors with different speeds,how to determine the better speed of the main motor is introduced.Through the analysis of the influence of different thickness control system on the thickness,accuracy and shape of products in the finishing mill,the suggestions on the selection of thickness control system are put forward.After the optimization of the equipment selection and parameter determination,the production capacity of the hot rolled strip production line can be increased,the burning loss can be reduced,the consumption can be saved and the product quality can be improved.
