| Rolling is the main production mode for copper strip, which is falling into hot rolling and cold rolling. Although, today, copper manufacturing industry product80%copper strip by hot rolling process, cold rolling process still act an important role., just because of the more than10millions tons quantity of supply and demand these years. Nowadays, the main production processes for copper strip production are continuous extrusion cold rolling and horizontal continuous casting cold rolling. The main technological process is melting—blank making—rolling—gnnealing—pruning—picking.Using continuous extrusion cold rolling to product copper strip is a new technological. This technological rely its energy saving and Environmental protection, high material utilization ratio, unstinted product length, high efficiency production and high product quality occupation the market quickly. Horizontal continuous casting cold rolling appeared in1950s,which is the main mode of copper strip production until now. The technological have a lot of advantages such as low cost, high efficiency production, low casting defect and so on. So the text aim at the two kinds of cold rolling technological, product’s microstructure and mechanical property, doing comparative analysis overall.Researching and discussing,which is better, and providing theoretical foundation for practical production.The paper analysis the microstructure pattern and mechanical property of the two kinds of technological’s slab, mid pass copper strip and products. Summarizing the variation of the microstructure pattern and mechanical property with the deformation increasing. And compare the similar deformation cold rolling copper strips’microstructure and mechanical property of the two technological. The result show that, when the deformation reach89%,the microstructure and mechanical property are approaching. For fitting width medium plate production, continuous extrusion cold rolling is better. |
