Annual output of 2.2million tons of brass belt production process design with brass band
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 country over 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 the future demand for brass will rise year by year, according to the current domestic production capacity, production has far cannot satisfy the market demand. Due to brass plate strip rolling, many scholars who come 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.
My topic is annual output of 2.2million tons of brass belt production process design with brass band. Conditions of existing equipment from China Shanghai Copper Co., Ltd., I complete the process design through a variety of system and achieved the desires of production . The factory equip melting furnace of copper ,which capacity is 5-8 tons ,with being chosen 5 ton as my output coming from one furnace . According to the thickness and width of production by calculating , removal amount of trimming , trimming allowance is decided . In the end, I can calculate the length of two products after casting . Made boiler H85 coil as well as for air conditioning needed for the cooling of the condenser tube , and indicators on the mechanical properties of the product demand is high, the market demand is bigger . H65 as hardware, springs and machine parts in everyday life, the market demand is stable and yields higher required to meet the social production. This design of copper alloy plate strip production process: by copper melting furnace heating with water after adjusting for holding furnace heat preservation and the analysis of the components into the semi-continuous casting machine casting, cast ingot billet, after milling surface to remove surface oxide layer to enter before stepping in front of the furnace for hot rolling mill for heat treatment, its purpose is to eliminate casting stress, ensure high temperatures of hot rolling plasticity, reduce the deformation resistance and improve the organization and performance of alloys. Out of step furnace directly into hot rolling stage, after the raw material mill into cold rolled thickness requirements, carries on the milling surface coiling. Entered the stage of cold rolling method rolling belt type, i.e., open book into the cold rolling mill, with q can be processed by the product reaches its maximum rate under pressure after coiling, the use of bell type annealing furnace for annealing. Refund after the fire products are under normal pressure to enter a mill after further down, until the rate of maximum pressure again. If has not meet the requirements of thickness, annealing; If has reached a thickness requirement, can the mill coiling, you need to complete the finished heat treatment, using 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 of the goods is packing into the Treasury, waiting for the delivery of the goods.
