鞍山科技大学本科生毕业设计 第 I 页 500开坯线材轧机设计 摘 要 线材的用途很广，在国民经济各个部门中，线材占有重要地位。据有关资料统计，各国线材产量占全部热轧总量的 5.3 15.3 。近年来，对线材性能及表面质量的要求越来越高。尤其是对线材化学成分，机械性能，晶粒组织及晶粒粒度都要做检验，符合标准方可出厂。所以，对线材的苛刻要求决定了新轧机及相关新技术的飞速发展。 本次设计是对线材生产中的粗轧机（开坯机）部分进行设计。首先，根据轧制工艺对轧辊基本尺寸进行了设计，然后又根据轧制力矩选择了电机。在主传动系统中，对轧辊进行了受力 分析和必要的强度校核，对机架也做了相应的校核。在设备改进方面，对 H 架进行了改进，改善了它的受力情况 ,提高了使用寿命。 通过本次设计使我对冶金机械的设计有了新的认识。但是，这其中还有很多的不足需要改进。能够完成本次设计离不开学院老师的支持，在此仅代表个人对提供帮助的老师表示衷心的感谢。 关键词： 线材生产，开坯机，主传动 nts 鞍山科技大学本科生毕业设计 第 II 页 A Design of 500 Wire rod Rolling Mill Abstract As the use of wire rod is very broad, In every department of national economy, Wire rod possess important position. According to relevant information statistics, The countries output of wire rod take amount of the completely hot-roll products 5.3 15.3 . In recent years, For the requirement of the surface quality and performance of wire rod, it is more and more higher.So many parameters to be inspected, especially for the chemical composition ,mechanical performance, Crystal microscopic organizes and Crystal microscopic size of wire rod, accord with standard side can be sold out. So new rolling mill and related new technology should be developed fast for the harsh requirement of wire rod. My design is aim to design for wire rod boil Pei rolling mill.First, According to rolling technology , the basic size of roll is designed , and then have selected motor according to rolling force.In main drive system, the strength of roll is also analysed, including the forces given to the rolls. The strength of the frame be analysed clearly.In the aspect of equipment improvments,H-bridle is an episode. During this span of over four months,new conception of machinical design have been improved.But several shortcomings also exist. Professors especially Professor Wang give contributions to me.So I am on behalf of m
