年产140万吨冷轧带钢论文

摘要

冷轧带钢具有表面质量高、性能好、品种多和用途广等特点。特别是随着汽车工业和家电行业的迅速发展，人们对汽车及家电外壳的质量和性能要求也越来越高，因此，发展冷轧板带钢十分必要。本设计是参照鞍钢三冷轧厂而进行的冷轧带钢车间设计，设计年产量为140万吨。本设计在参考鞍钢三冷轧厂的设备条件下，参照了诸多文献及实际资料，以年产量为基础，结合各产品市场前景合理地分配了各产品产量，并制定了轧制制度，校核了部分主要设备及车间年产量，综合了各项技术经济指标，并绘制了车间平面图。此外做了篇关于张力自动控制技术方面的专题论述。并附有一篇短暂的增加微织构弹流润滑间的薄膜厚度方面的英文资料及其中文翻译。

关键词：冷轧带钢；工艺设计；压下规程；张力自动控制；薄膜厚度

Abstract

Cold-rolled strip has many characteristics, such as high surface quality, better performance, more varieties and so on. In particular, as the development of automobile industry and home appliances industry, it has been demanded higher quality and performance in the shell of cars and home appliances. Therefore, it is very necessary to develop the cold-rolled strip. The cold rolling strip plant was designed with annual yields of two million tons on base of the third cold-rolled factory of steel group of An'shan. The design is based on annual production, haved combined all products market prospects and distributed the output of all products rationally, developed the Rolling Process and Integrated Various economic indicators which is based on the equipment of the third cold-rolled factory of steel group of An'shan and many practical information and literature, then Painting in the workshop plan. Furthermore, a monographic study related to tension automatic control technology of stainless steel craft, and encloses one about modelling of the effect of film thickness on cold strip rolling information in English and it is Chinese translations.

Key words: Cold-rolled strip plant; process design; reduction of rules; tension automatic control technology; film thickness
