棒材毕业设计.docxVIP

本科生毕业设计说明书(毕业设计)题 目：设计年产量为48万吨的棒材厂车间，典型产品：Q235圆钢，Φ22mm，占年产量14%学生姓名 设计年产量48万吨的棒材厂,摘 要近年来，世界棒材生产先进企业日益重视高附加值产品的研发与制造，自主创新能力日益成为棒材生产企业在高端市场竞争的重要武器。虽然我国棒材产业在生产规模不断扩大、在技术进步、产品研发方面也取得了可喜成效，在棒材生产线过程中，我国已掌握切分轧制技术并实行生产，对于传统的孔型中轧制技术尤为成熟，特别是控制轧制、控制冷却的技术的应用，保证了棒材的质量。但与世界先进水平还有相当大的距离。 本设计计划在包头市南面建立设计年产量为48万吨的棒材厂，主要生产Φ12～Φ40mm的圆钢。代表产品为Φ22mm的q235圆钢，其产量为年产量的14%。产品质量执行国家标准。主要包括产品方案的制定、孔型设计、主辅设备的选择、生产能力的计算、车间平面布置、主要经济技术指标等内容。关键词：棒材；圆钢；设备；孔型；车间布置Design a bar plant of 500000 tons production capacity,AbstractIn recent years, the world advanced bars production enterprise pay more attention to the research and development of high value added products manufacturing, the independent innovation capacity is increasingly becoming bars production enterprise in an important weapon in the high-end market competition. Although our countrys rod industry in the production scale expands unceasingly, in technology development, product research and development have achieved satisfactory results, but with the world advanced level and considerable distance. The design plan to establish design annual output of 480000 tons of bar mill in the south of Baotou City, the main production of steel bar diameter of 12 ~ 40mm in diameter. Representative products of phi 22mm Q235 steel, and its yield is 14% of annual output. The quality of the products the implementation of national standards. Including product plan, pass design, equipment selection, production capacity calculation, workshop layout, main technical and economic indexes etc..Key words:Bars;Round steel;Equipment;Pass;Workshop layo目录摘 要IAbstractII目录III第一章 绪论11.1 设计背景及意义11.1.1 国际市场11.1.2国内市场11.1.3 我国棒材产业的发展趋势21.2 厂址选择21.3优势条件21.3.1 包头地区地方优势21.3.2 能源情况31.3.3包头地区交通情况31.4技术条件分析4第二章 棒材产品大纲52.1产品方案的制定52.1.1 产品方案的内容：52.1.2产品方案的选择原则：52.1.3 编制依据：52.1.4产品方案的确定：62.2产品标准与技术要求62.2.1产品的标准62.2.2圆钢相关技术要求72.3 金属平衡表82.3.1确定年计划产量所需之坯料量82.3.2金属消耗组成8第三章 制定车间生产工艺103.1确定轧机的类型及布置形式103.1.1 轧钢机选择的原则103.1.2确定轧机的布置形式103.2确定产品的工艺流程143.2.1制定工艺流程的依据143.2.2生产工艺流程153.2.3 工艺流程概述153
