【摘要】 中厚板产品广泛应用于油气输送管线、船舶、桥梁、容器、锅炉、海洋构件、建筑等国民经济的众多领域。目前，我国中厚板轧机的装机水平、设备能力、产量和能耗，与先进国家相比，存在很大差距。其中不少是二手设备，工艺落后，产量低，质量差，缺乏市场竞争力，有待于技术改造。秦皇岛首钢板材有限公司的四辊可逆轧机，是由西班牙购进的二手设备，因为设备能力的限制，在生产过程中，采用限制压下量轧制，压下规程也严重不合理，严重制约着产量的提高。本文首先通过理论分析，以西姆斯热轧公式为基础，建立新的轧制压力公式，并用实测值对其进行修正，提高了计算精度。然后用ANSYS有限元软件对轧机的主要零部件的强度进行模拟计算，综合考虑轧机的基本状况，提出了轧机的改造方案。为了验证模拟计算的结果，对轧机进行了测试实验，并将实测值与理论计算值进行对比分析,验证了理论计算结果的正确性，并重新选择了主电机。最后，对轧机的整体状况进行分析，以充分发挥轧机能力、产量最高为目标，同时兼顾产品质量，建立了数学模型，对轧制规程进行优化设计。更多还原

【Abstract】 The plate products are widely used in many fields such as pipeline of petroleum and natural gas, shipping, bridge, container, boiler, oceanic component, construction and so on. At present，there is a large distance about middle-thick plate mill between at home and advanced country in the installation level, equipment ability, output and energy consumption. A number of these are tender equipment. The fall behind technic, the low output and the poor quality make the poor production competitive power. It is need to be redevelopment. The four reversing high mill of QHD plate mill SG is a tender equipment from Spain. Because of the limited of the equipment ability it must use the limited gauge reduction during rolling. The pass schedule is not reasonable, too. It restricts the raising of output seriously. In this study, at first，We will establish a rolling force formula based on the Sims formula, and improve it with the test data. Simulate calculate the intension of the mill’s main parts using SNSYS. Advanced the reconstruct project.Testing the mill in order to validate the calculate result. and choose the new main motor. At last, analyzed the whole mill’s condition, established mathematical model with the object of largest output. Optimum designed the pass schedule.更多还原
