摘要：随着电子信息、生物技术、航空航天、海洋工程等技术的发展，国内市场对铜板带的品种及质量要求越来越高。当今世界高精铜合金板带大约占铜加工总量的２０％。中国板带材的产量和消费量都处于世界第一位，但是中国高精铜板带加工技术落后也使我国成为了世界上铜板带材进口量最大的国家。作为新一代的大学生，我们每个人都有责任和义务进行相关的研究。22868
本次我选的课题是1.2×500×2000mm深拉用黄铜板的生产工艺规程设计。课题来自于导师，选中课题后通过大量的文献检索，及在中铝两周的生产实习对课题内容有了深入的了解和认识。根据设计任务书要求，对产品的所有轧制制度的制定和力能参数的计算及设备能力、强度的校核等来完成工艺设计，达到产品所要求的交货状态。首先根据产品的用途所需要的性能确定了设计产品的牌号为H65黄铜，原料类型为半连铸坯，原料尺寸为170mm×5200mm×6678mm、成品尺寸为1.2mm×520mm×2000mm，交货状态为软态。
H65黄铜板的主要生产工艺流程:配料--熔炼--半连铸——切头尾--—两辊热轧-- 切头尾——铣面（双面铣）-四辊粗轧--中间退火（罩式退火炉）—精轧——成品退火（气垫式连续退火炉）——清洗——矫直——分切（纵、横剪）—成品检验--包装入库。
生产过程中中间退火的次数需要根据轧件的加工硬化程度来确定，本设计中H65黄铜允许的最大总加工率为70%，而根据设计数据来看，本设计中黄铜的总加工率是90.4%，这决定了必须进行中间退火才能继续轧制。而计算中间退火次数的最主要考虑因素是减少能耗和轧制时尽可能的压下到最大允许加工率，充分利用轧件的塑性变形，避免能源的浪费。当整个退火完成后，则进行最后的剪切矫直、产品质量检测，确认产品符合交货要求则可包装入库，等待交货。尺寸精确板形好，表面光洁性能高即可归纳产品的生产技术要求。
本设计主要阐述H65黄铜板材的生产技术要求和关键生产工序（熔炼、铸造、铣面、轧制及退火等）的工艺的特点。根据中铝上海铜业有限公司已经有的生产流程以及产品，对产品生产熔炼工艺进行制订、轧制制度编制、辊型制度制定、电机能力校核、轧辊强度校核等，在设计的过程中利用电脑软件Visual Basic编程语言，对轧制力和轧制力矩进行计算程序的编制，利用电脑软件Auto CAD，对轧辊图进行绘制。从而设计出切合实际生产标准及应用场合的产品。

1.2 x 500 x 2000mm deep drawing with the production technological process design of brass
Abstract：With the development of electronic information, aerospace, marine engineering, biotechnology and other high-tech, the domestic market for the variety and quality of copper with the increasingly high demand. In today's world of high refined copper and copper alloy strip copper accounted for about 20% of the total. Production and consumption of Chinese plate and strip are ranked first in the world, but because of China's high-precision processing technology behind the copper strips, so that our country is also the world's imports of copper strip largest country. As a new era of college, I also have the responsibility and obligation to carry out related research.
I chose this topic is 1.2 × 500 × 2000mm deep drawing with a brass plate production process planning. it came from the instructor, after the passage of a large number of topics selected literature searches, and in the production of aluminum-week internship with the depth of the subject content knowledge and understanding in. According to the design requirements of the mission statement, computing power and equipment capacity to develop products and systems can all rolling parameters, such as checking the strength to complete the process design to achieve the required product delivery status. First, determine the design of the product grades H65 brass, semi-continuous casting material type, material size is 170mm × 5200mm × 6678mm, finished size is 1.2mm × 520mm × 2000mm, delivery status based on the performance required for use of the product soft state. 1.2×500×2000mm深拉用黄铜板的生产工艺规程设计+CAD图纸:http://www.751com.cn/huaxue/lunwen_15685.html
