第 1页设计说明本设计为年产量 180 万吨的中厚板车间,通过对中厚板市场的调研,介绍了中厚板的发展状况,分析了中厚板的市场需求,并针对目前的技术状况,制定出了合理的产品大纲和金属平衡表。以典型产品 Q235 (10mm ×1700mm × 6000mm 、25mm ×1000mm ×6000mm 、4010mm ×1450mm ×4000mm ) 钢板为基础,通过确定典型产品的工艺流程,确定了轧机的布置形式和车间各设备的选用,并制定出典型产品合理的压下规程,计算出轧制力能参数,如:轧制力的计算、变形抗力的计算和传动力矩的计算等。校核轧辊强度并计算电机的容量,以选用合适的轧辊和电机。确定车间工作制度和年工作时间,计算了轧机的年产量, 根据典型产品的工艺和轧件的尺寸等,确定车间平面布置,如合理的设备间距、仓库面积等,并画出车间平面布置图。分析车间的综合经济指标。并采取有效的环境保护措施,如车间的绿化、废气和废渣的再回收等。关键词: 中厚板车间, 产品大纲、金属平衡表、轧制力、传动力矩第 2页 Design Notes The design for the annual production of180 million tons of plate plant, plate market research, the development of the plate, the plate market demand, and the current state of technology, to develop aa reasonable outline of the products and metal balance sheet. Typical product Q235 (10mm × 1700mm × 6000mm, 25mm × 1000mm × 6000mm, 4010mm × 1450mm × 4000mm) steel-based, to determine the typical products of the process, to determine the the mill arrangement of workshop equipment selection, and to develop typical products and reasonable reduction procedures to calculate the rolling force parameters, such as: rolling force calculation, the calculation of the deformation resistance and transmission torque calculation. The check rolls intensity and calculate the capacity of the motor to the appropriate choice of rolls and motor. To determine workshop work systems and working hours, calculated the annual production of the mill, according to the typical product of the process and the size of the rolling determine workshop layout, such as device spacing, warehouse area, and draw the workshop floor plan . Analysis of the economic indicators of the workshop. And to take effective environmental protection measures, such as the greening of the workshop, waste gas and waste recycling and soon. Keywords: plate workshop, outline, metal balance sheets, rolling force, deformation resistance, drive torque 第 3页目录设计说明……………………………………………………………………………...1 1前言………………………………………………................................................... 8 我国中厚
