1results about How to "Reduce labor loss" patented technology

The application discloses a surface-defect-free high-purity oxygen-free copper wire manufacturing method based on continuous extrusion, relates to the field of non-ferrous metal precision machining technology, and directly adopts an up-drawing continuous casting billet to extrude a target specification wire rod in one step through continuous extrusion, so that a plurality of drawing processes and at least one intermediate annealing process in a traditional process are completely omitted, a process flow is compressed by more than 60%, a production cycle is significantly shortened, equipment investment, labor cost and energy consumption loss are reduced, wire rod production efficiency is greatly improved, large-scale production cost is greatly reduced, and the application has a strong industrialization advantage; the continuous extrusion process introduces large plastic deformation, can strongly break original as-cast coarse grains, and simultaneously compacts and eliminates internal defects such as pores and shrinkage porosity generated in the up-drawing continuous casting process, and improves wire rod density. Compared with a traditional processing method, the wire rod prepared by the application avoids problems such as annealing oxidation, uneven structure and performance fluctuation, and the elongation of a finished product is greater than or equal to 40%.
