The design of workshop of annual output of 20000 tons
of high precision copper strip
Abstract: At present our country more than about 4 oo copper belt production enterprise, but the annual output of more than 5000 t only a dozen companies. From the point of the total, the copper strip production capacity of the basic can meet the needs of national economic development, can satisfy the general requirements of the market at present and a surplus. But due to the overall level of production technology and equipment is relatively backward, and due to various reasons some of the large and medium-sized copper belt production enterprise of the imperfection of the existence of form a complete set of production equipment, the copper belt processing industry in our country still exists serious varieties, quality and specifications of structural contradictions, part of the high precision and special copper strip production capacity and production still cannot meet the increasing market demand. Emerging industry in recent years, the use of special copper strip, such as transformer winding copper materials, electronic connectors and other high precision copper strip, there are still large supply. At present, the domestic large-scale copper belt production enterprise only in luo yang copper processing group co., LTD., Beijing golden eagle copper company, ning bo jin tai industrial group, Shanghai copper company, guang zhou copper factory, such as a few, far cannot satisfy the needs of the development of national economy, leading to a large number of imported high precision copper strip, and imports increased year by year.
For such development present situation and problems, many engineers rolling method is formulated in the process of rolling, including the selection of various process parameters, etc.) and ingot casting process were studied. Fundamentally understand the causes of defects and mechanism, and puts forward many improving measures aiming at specific problems, are to some extent, has obtained the good effect, be able to increase production, increase yield, make the production of copper alloy plate strip rapid development.
I chose in the design of the annual output of 20000 tons of high precision copper plate belt workshop design, products mainly for special copper sheet and copper strip used in electrical, mechanical, etc. According to the on-the-spot investigation to understand the chinalco Shanghai copper co., LTD., after the plant layout, equipment conditions and so on, through independent development of rolling technology, rolling parameters, checking mill capacity, and so on steps to complete this workshop design. The workshop of the main technological process is: in the product design, melting into the semi continuous casting machine casting, cast ingot billet, enter step furnace heating. Out of step furnace after directly into the hot stage, after waiting for raw material rolled into the required thickness, and milling surface. Entered the stage of cold rolling method rolling belt, then according to the specific technical requirements and conditions for the intermediate annealing. Refund after the fire product has the ability to return to normal pressure, after entering the mill rolling under further pressure. If has not meet the requirements of thickness parameter, then continue to annealing; If already meet the thickness requirements, can the mill coiling, according to needs to carry on the finished product to heat treatment, the air cushion type annealing furnace. When, after the completion of the whole annealing for final shear straightening, product quality inspection, confirm the product conform to the requirements of the delivery can packaging warehousing, waiting for the delivery of the goods.
