Annual output of 3.3 thousands tons of white zinc copper 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.
    This time I choose the topic is the annual production design of the work shop process 3300 tons of copper nickel zinc strip. Topic from tutors, selected to design issue through literature retrieval, and aluminum two weeks in the production practice have a deeper understanding and the understanding to the subject. According to the requirement of design task book, calculation and equipment capacity, strength parameter setting and force on all rolling system products of checkout to complete the process design, to meet the requirements of product delivery status. Performance according to the products need to determine the design product grades for the BZn18-18 and BZn15-20, type of raw materials for continuous casting billet, raw material size is 16mm × 430mm × 5000mm, finished size is 1.6mm × 400mm and 0.6mm ×400mm, delivery status for Y and Y2; the main production process, the design of strip: by smelting furnace heated copper water after holding furnace insulation and the analysis of the composition of adjustment, into a horizontal continuous casting machine casting, cast billet, surface oxidation layer was removed by milling rolls. Into the cold stage to take belt rolling, namely the book into the cold rolling mill, the products reach the maximum pressure which can process rate after coiling, intermediate annealing by bell type annealing furnace. After back after the fire products can be normal pressure, into the corresponding mill near one step down, until once again reached the maximum compression ratio. If you have not yet reached the thickness of product requirements, continue annealing; if it has reached the thickness of product requirements, can be a mill coiler, the finished product heat treatment, using the air cushion type annealing furnace. When the whole annealing is completed, then cut the final straight, product quality testing, to confirm the products meet the delivery requirements, packaging and warehousing, wait for delivery. Technical requirements for products can be summarized as follows: the exact size shape, smooth surface and high performance, in order to achieve the technical requirements for products is the basic premise of the design. The equipment selection in the design of the main reference of equipment used in aluminum production, the selected frequency equipment 1.5T with core melting furnace, holding furnace 4T, horizontal continuous casting machine, two roller reversible roughing mill, mill, four stick twelve rod rolling mill, bell return air furnace, annealing furnace, transverse shear machine, slitting machine, thick, thin longitudinal shear machine etc.. Tounder stand the process of calculation of rolling force and rolling moment clearly drawn up the reasonable VB language emerged, and use CAD to draw roll, roll force and bending torque diagram and workshop layout, fully reflects the application of computer in materials, advancing with the times. Before checking part reference equipment strength and motor ability was calculated toverify the contents of. The design principle is to ensure that the design quality of the products under the premise, reduces the production cost as much as possible, improve production efficiency. 年产量3300吨锌白铜板带的车间工艺设计(2):http://www.751com.cn/huaxue/lunwen_15380.html
