Design And Research On Engineering Of 60kt/a High Precision Copper And Copper Alloy Plate, Sheet And Strip

Copper and copper alloy plate,sheet and strip are fundamental material in many industrial sectors of a country's economy. With the development of the country's economy and the reshuffling of market consuming products' structure, the new consuming applications have brought an ever-increasing demand on more and more high precision copper and copper alloy plate,sheet and strip. Therefore, the development of high precision copper and copper alloy plate,sheet and strip' has become a priority in order to meet the market requirement.Presently most of the copper and copper alloy processing enterprises in this country, are draggled in the technology and equipment, smaller in production scale, and irrationality in product variety. The throughput of high precision products can't meet the ever-increasing demands from many industries, A great deal of high precision products have to be imported. To solve this problem, therefore, the design and research of modern advanced hot breakdown rolling process plays a important role for restructuring copper and copper alloy plate, sheet and strip and answering the market needs for high precision copper and copper alloy plate, sheet and strip.With reference to the developing trend in processing technology domestic and abroad, and by studying the market demands for variety and quality, in this application, the author proposes a main prepare method of big cold rolling stock that induction melting, continuous/semi-continuous casting big slab and hot breakdown rolling. After the hot rolling, the material is to be further reduced by cold rough rolling and finish rolling. The process route is: melting/casting big slab, hot rolling, cold breakdown rollingand cold finishing rolling, and final processing. The total capacity of this project is 60kt/a. Some extra space is planned also for future development.Following the states' industry policy and the market demand domestic and abroad , the project is a high precision copper and copper alloy plate, sheet and strip producting line with transformer strip as its leading product, adopting advanced and mature production technics, with equipment reaching or adjacence world advanced level ,the product quality accords with international standard, and with high economical efficiency.
