Transformer special copper production process design
Design General Description: In recent years, with China's sustained and stable development of copper material production has entered a rapid development period, in 2008 production reached 3.196 million tons, of which about 600,000 tons copper strip to become the world's largest producer of copper strips. Although China's copper strip production capacity and output have a more substantial increase, but the copper belt lower overall level of enterprise technology and equipment, the production of small-scale, enterprise-scale average of less than 3,000 tons / year, copper strip varieties structure unreasonable phenomenon, especially lead frame material, RF cable with transformer copper and other high precision copper strips products, whether it is the variety, quality and quantity can not meet the needs of the market, the import volume has continued to rise, 2008 copper strip imports amounted to 237,000 tons.
It is predicted that in 2010 domestic demand for copper strip at 105 million tons, has been considering the current domestic projects under construction with the formation of copper production capacity in 2010 with a copper supply gap is also about 200,000 tons.
For copper plate strip rolling, many scholars at home and abroad, the development engineers from rolling method, ingot craft were studied, which mastered the causes of defects, mechanisms, made many improvements measures, and achieved good effect.Which can increase production, increase yield, making the further development of copper strip.
I chose this topic is dedicated transformer copper production process design. Through the aluminum under the conditions of existing equipment, the development of efficient process design and improve yields. Improvement of existing problems, knowledge and practice, which is the focus of the study graduation.
This paper discusses the T2 copper with high precision production technology requirements of its key production processes (melting, casting, milling surface, rolling, annealing, pickling, etc.) of the process characteristics. To this end we visited Chinalco Shanghai Copper Co. production site
Chinalco Shanghai Copper Co., Ltd. is a subsidiary of Aluminum Corporation of China, on August 28, 2006 in Shanghai was incorporated. Company is engaged in non-ferrous materials processing and export business, the main products are copper and copper alloy sheet, strip, foil, tubes, rods, wire, type and composite materials, and semiconductor materials and high-purity metals. Copper products all grades, types, specifications Qi, a high level of technical standards, the products are widely used in electronic information, electric power facilities, automotive, marine, aerospace, defense industry and major equipment and other fields.
"Twelve Five" period, the company will be full-depth structural adjustment as the driving force to ensure that the initial realization of "doing fine sheet with foil, copper take the high road" strategic transformation, showing an advanced concept, mechanism innovation; development prospective, production of fine; operating flexibility, and risk control norms; talented personnel, team stability; flat organization, management, and efficient new look of the Shanghai copper processing enterprises. The main production equipment is imported from abroad, in its 2002 annual production of 30,000 tons of copper in the main belt and phosphor bronze with tin, of which 92 years production equipment production of about 20,000 tons. 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 copper ingot, alloy varieties subject to certain restrictions.
