Abstract    In recent years, with the sustained and stable development of China's national economy,the production of copper material also entered a period of rapid development, production reached 3.196 million tons in 2008, of which about 60 million tons of copper plate and strip, becoming the first a large copper-producing countriesin the world. China's copper strip production capacity and production has dramatically increased, but the copper to lower the overall level of enterprise technology and equipment, small-scale production, the average firm size is less than 3000 tons / year, copper strip varieties The structure is becoming an unreasonable phenomenon, especially the lead frame material, RF cable transformer, Copper belt and other high-precision copper products, whether the variety, quality and quantity are far from plate and strip imports amounted to 237,000 tons.
    It is predicted that by 2010 the domestic copper strip demand of about 1.05 million tons, considering the current production capacity of domestic copper belt in the construction of the project, also about 20 million tons of copper supply gap in 2010.   
Due to brass plate strip rolling, many scholars who from china or abroad and engineers have formulated the process research in the rolling method, grasped the defect causes, mechanisms, put forward a number of improvement measures, and achieved good effect.Which can increase production, increase yield, making the copper strip further development.
I chose this topic is 1.0 × 550 × 1800mm decorative brass plate production process design. I chose brass grade is H80. H80 is a high number of single-phase brass, and H85 similar performance, scalability, and deep-drawing performance, can be plated is good, high strength, high corrosion resistance, used in construction, household decorations, car heatsink , electrical connectors, wind, thin-walled tubes, bellows papermaking network and building supplies.
In order to formulate reasonable production process, we are led by an instructor, visited the Shanghai Aluminum Copper Limited. Chinalco Shanghai Copper Co., Ltd. is a subsidiary of Aluminum Corporation of China, on August 28, 2006 in Shanghai was incorporated. The main production equipment is imported from abroad, the production line hot rolling, cold rolling, annealing equipment, more advanced, but a lack of cold rolling and annealing, finishing processes still need to improve; since casting equipment technology and equipment level is limited, mainly produce brass ingot, alloy varieties subject to certain restrictions.
Visited the aluminum factory, I understand the conditions of the existing equipment and production processes. I chose the New Line production process. I want to aluminum in terms of existing equipment and provides a variety of technical reference information for the design principles, does not allow inpidual devices beyond the actual technical indicators; Chinalco Shanghai Copper Co., Ltd. under the existing production processes and products, carried out on product formulation smelting process, the preparation of the rolling system, roller-type system formulation, motor ability check, roll strength check, in the design process using computer software Visual Basic programming language, for rolling force and rolling torque calculation procedure preparation, the use of computer software Auto CAD, on the roll chart drawing. Thus designed to meet the actual production of standard products - decorative brass H80, and its production processes, while also based on Chinalco Shanghai Copper fieldwork situation, understand the various copper production processes, plant in now some variety of equipment, as well as the specific location of each device, as a reference, and then use mapping software to map out their own Auto CAD design products plant design drawings.
Through the inspection and collection of information, we learn that it still can not meet the needs of the rise of imports despite the continuous development of the production for China's copper strip. Particularly with the domestic production of high-precision copper variety, quality and quantity can not meet market needs, which is one of the main reasons caused massive imports of copper in our country. 1.0×550×1800mm装饰用黄铜板的生产工艺设计(2):http://www.751com.cn/cailiao/lunwen_6994.html
