摘要

板带材在国民经济各部门中具有广泛而重要地应用.由于板带材使用部门对板形精度地要求越来越高,使板形控制成为现代高精度板带轧机地关键技术和重要地技术发展方向.这样四辊轧机地板形控制能力就显得很有限,边部减薄也很严重.虽然采用了很多办法来改善板形,但是效果都不够理想.后来发展了六辊HC冷轧机,它是当今板带轧机改造和新建地主要机型.该种机型

采用了一对可以移动地中间辊,并使用了工作辊弯曲和中间辊弯曲.通过这些技术,减少了带钢地边部减薄,提高了轧后带材板形精度,并能明显地降低工作辊弯辊力,带材地板形得到了很大改善.

在这次设计中,采用了这一机型,介绍了1050可逆式六辊HC冷轧机地基本参数和技术特点.

Abstract

In every department of national economy, plate and strip has extensive and importantapplication.The precision of plate and stripacquired by department is becoming higher and higher. As a result, shape control becomes thekey technique and important develop direction for modern times high precise rolling mill. As it is strongly desired that edge-drop should be improved, the four-high mills` ability seem to be very limited and the edge-drop of cold-rolled strips is very serious. Though many ways have been used to imp

rove the shape of the cold-mill strip, the effect is not well enough. Later, a six-high HC mill was developed, which is one of the main type in the rebuilding and designing strip mill. It has a pair of middle-roll which can shift. Also, it has bending work rolls and bending middle rolls. With using these techniques, the edge-drop of strips is reduced, the accuracy of stripshape control is improved and the bending force on work rollers is decreased obviously, the thickness accuracy and flatness get to very greatly improve.

The type of HC mill is appliedin this design. The basic parameters and technique characteristics of the 1050 reversing 6-high HC cold rolling mill are introduced.

Keywords: edge-drop。 6-high HC mill。 middle roll shift。 middle roll bend

第1章绪论

1.1世界及我国钢铁工业地发展

钢铁工业属原材料工业,刻字笔是国民经济中地基础工业,是社会发展地重要支柱.自从一百多年前形成钢铁大工业生产以来,钢铁工业获得了重大发展.世界钢产量1880年440万吨,1988、1989年达到7.8亿吨地最高水平,目前保持在7.3亿吨左右；在质量、品种方向,向洁净钢和增加合金钢地方向发展.

虽然钢产量已不被作为确定一个国家经济实力最重要地指标之一,但是,悬浮机器人一个国家地科学技术进步水平怎么自制纳米胶,在很大程度上仍取决于其钢铁工业地现状和发展.钢铁工业不仅决定了一个国家地经济独立性逆变电源模块,而且决定了其政治独立性.因此,世界各国地钢铁工业在金融、信贷和税收优惠诸方面都受到政府相当大地支持.

随着科学技术地不断进步和发展扬声器结构,新型结构材料不断出现（如铝合金、钛合金和镁合金,结构用塑料,合成材料、非晶材料和微晶材料,经特殊处理地木材等）,在工业发达国家中这些新型结构材料地消费量占所有结构材料地比例已达14~18％,但是,由于钢地性能优越（强度高、塑性好）,生产和消费都比较经济,在钢地大多数应用领域中尚无可与钢匹敌地材料.
