河北联合大学轻工学院 QINGGONG COLLEGE, HEBEI UNITED UNIVERSITY 毕业设计说明书 设计题目：年产200万吨1580热轧带钢生产线工艺设计 摘 要 本设计任务为年产0万吨热带连轧车间选择20mm厚坯，双粗可逆布置。产品范围1.~18mm，典型产品5mm。设计内容包括建厂依据，轧制规程计算，轧制图表，年产量计算，凸度规程计算，电机发热校核，轧辊强度校核，辅助设备校核，金属平衡、燃料消耗计算。 为了生产高质量的，热轧厂装备有高效的带钢轧制模型和调节系统，从而使带钢厚度、板形、宽度、终轧和卷取温度的控制精度极高。能够使产品达到设计产量和品种质量的要求，满足市场需求。 关键字热轧带钢Abstract Designed to complete the design of the task book requirements (more than 2.0 million tons annual output of varieties of tropical plant and rolling). Choice of 250mm thick billet, dual rough layout reversible binding. Product range 1.5 ~ 18mm. Typical Product 5mm. Wide varieties of product requirements, good quality. The basis of content, including plant design, rolling a point of order, the crown of order, the rolling charts, annual production, the crown of order, the electrical heating calibration, intensity calibration roll, check auxiliary equipment, metal balance, fuel consumption calculation. In order to produce high quality hot rolled plate with the car, rolling on the piece thickness, convexity, surface finish requirements are high, the temperature more stringent system. Take roll edge heating, laminar flow edge block, to ensure thermal residual stress in a small volume products. Instrument using the new crown, high crown of information processing to achieve crown, flatness control, so that smooth surface, size and high precision cold-rolled to provide qualified for the follow-up coil. New plant is equipped with hot-rolled strip steel rolling technology and highly efficient model and conditioning systems, so that the strip thickness, flatness, width, end-rolling coiling temperature control and high accuracy. Enable the production of products to meet the design requirements of the quality and variety to meet market demand. Keywords 1580 hot rolling mill, double reversible roughing, CVC rolling, strip for car 目 录 摘 要 I Abstract I 引 言 1 第1章 文献概述 2 1.1热轧宽带钢轧机工艺装备的新发展 2 1.2发展中的问题 5 第2章 建厂依据及产品大纲 6 2.1建厂依据 6 2.2产品大纲 6 2.2.1 坯料规格和技术参数 7
