辽宁科技大学本科生毕业设计 年产8万吨冷轧薄带钢车间工艺设计 及森吉米尔轧机轧辊使用及质量控制 摘要 本设计说明书是参照XX冷轧厂设计的年产8万吨冷轧带钢厂。其典型产品为：SPCC 0.22×995 mm。 关键词：冷轧带钢；车间设计；轧制规程；轧辊 ABSTRACT The design is about the process engineering design of a cold rolling strip mill plant, which produces 80.000 per year,according to Shougang Cold Rolling Strip Mill Plant.Its tipical production is SPCC 0.22×995.This paper is composed of four parts. The first part is the introduction, which briefly sum up the present development, interrelated technology as well as the development orientation of the cold rolling strip. The second part is the main part referring to Chapter 1 to Chapter 7, which particularly introduces how to design each tache of the production of the seamless steel tube mill. According to the production of a year and these productions’ prospect in the market, I raaesonably distribute the production of them, design the rolling operation system for the product, check the rolling mills’ producting capacity and calculate the economic qualification, and draw a plan figure for this workshop. In the part three, I particularly discuss the use of the mill, discuss mills’ components and manufacture, grinding, configuration and effect on product quality in detail. Key words: cold rolled strip, workshop design, rolling, roll 目录 摘要 I ABSTRACT II 1 综述 1 1.1 冷轧薄钢板生产的发展概况 1 1.2 冷轧薄板生产特点 2 1.3 冷轧板带钢的轧制工艺特点 4 1.3.1 加工硬化 4 1.3.2 工艺冷却与润滑 4 1.3.3 张力轧制 6 1.4 冷轧生产工艺流程 6 1.4.1 酸洗 8 1.4.2 轧制 9 1.4.3 精整 10 1.4.4 镀锌 10 1.4.5 矫直 11 1.5 冷轧产品的技术要求 11 1.6 冷轧机的发展历史 12 1.7 冷轧机的布置形式 14 1.7.1 单（双）机架可逆式冷轧机 14 1.8 轧机方面新技术 16 1.8.1 HC 轧机 16 1.8.2 CVC(连续可变凸度)轧机 16 1.8.3 UPC (万能板形控制)轧机 16 1.8.4 CR轧机 17 1.8.5 各个机组的联合生产技术及短流程的进展 17 2 产品大纲及金属平衡表的制定 20 2.1 冷轧产品方案 20 2.2 产品大纲 20 2.3 坯料的确定 21 2.4 生产方案 22 2.5 金属平衡表 23 3. 轧制工艺流程 24 3.1 冷轧板带钢生产的工艺流程 24 3.2 冷轧板带钢各机组生产工艺流程 24 4 轧制制度的制定 26 4.1 压下规程 26 4.2 速度制度 27 4.3 张力制度 27 4.4 辊型制度 29 5. 设备参数的选择 30 5.1 设备组成 30 5.1.1 1350mm推拉酸洗机组 30 5.1.2 20辊设备介绍 31 5.1.3 脱脂机组设备的组成 35 5.1.4 环保型燃气强对流罩式炉 36 5.1.5 RBG8-135x430型强对流电加热罩
