摘要 Abstract PAGE 2 PAGE 1 毕业设计说明书 设计题目：年产70万吨棒材车间工艺设计 2012年05月20日 Abstract 摘要 PAGE I 摘 要 此次设计年产量70万吨，品种为圆钢和螺纹钢的小型棒材厂，其规格分别为Φ18～60mm圆钢，Φ12～50mm螺纹钢，在此选择Φ22的螺纹钢为典型产品。 本车间设计的主要依据是现代棒材生产工艺过程的理论，参阅了国内有关棒材轧机的先进工艺、轧机的装备、技术、孔型系统及一些辅助设备的论述，并参照承钢棒材厂，取一部分技术参数而设计了此车间。 此设计说明书以设计任务书出发，首先论述了建厂的必要性和可能性，然后按照车间设计的步骤进行设计，主要是产品大纲的制定、轧机的选择、孔型系统的选择及典型产品的孔型设计、力能参数的计算及校核、辅助设备的选取等。 此外，本文附有轧制图表、电机负荷图、孔型图、配辊图及车间平面图，以便参考。 关键词:棒材轧机；设计方案；孔型设计；轧机形式；技术参数 ABSTRACT This paper designs a small bars workshop to produce about 700,000 tons round bars and rebars. And their diameter is 18 to 60 mm or 12 to 50 mm. The paper chooses 22 mm rebar as typical produce. The paper is based on the theory of production process about modern bar, and refers to domestic advanced technics of bar mill and discussion about equipment of rolling mill, technology, pass system, auxiliary equipment and so on. Moreover, the paper consults the bar workshop in steel rolling mill of Chengde, and adopts some technical parameters. The paper proceeds from design assignment book. First, it studies the necessity and feasibility of designing this workshop, then designs the workshop according to elementary process, which mainly includes framing product outline, selecting rolling mill, selecting pass system, computing mechanics parameters and checking them, selecting auxiliary equipment and so on. In addition, there are several design charts: rolling program, load diagram of rolling target, pass system, pass positing, plan view of plant lay out. All of these graphs will help you understand the design consideration and design concept better. Key word: bar mill, design scheme, pass system, mill model, mechanics parameters. 目 录 目录 PAGE 98 目录 TOC \o 1-3 \h \u 23329 摘 要 I 28432 ABSTRACT II 32245 引 言 III 26013 第1章 建厂的经济技术依据 1 21578 1.1建厂分析 1 12101 1.1.1建厂的必要性 1 8578 1.1.2建厂的可能性 1 6318 1.2 厂址选择 2 818 第2章 产品大纲及坯料选择 3 26238 2.1 产品大纲的确定 3 23361 2.1.1 编制产品大纲的原则 3 19314 2.1.2 产品方案的主要内容 3 20518 2.1.3
