Problems solved by technology

[0003] At present, the production process of copper strip products is mostly produced by electrolytic copper smelting. The specific process is: scrap copper-anode copper-cathode copper-smelting-casting billet-billet processing-heating-hot rolling blanking-cold rolling-surface cleaning and other processes, not only the production process is complicated, but also consumes a lot of materials and energy, which will cause certain pollution to the environment. Therefore, the use of scrap copper as raw materials to produce environmentally friendly copper strips can reduce the cost of raw materials and reduce the cost of environmentally friendly copper strips. production is very important

Abstract

The invention provides a preparation method for an environment-friendly copper alloy band material. The preparation method includes the following steps of separation, classification, adjustment of the raw material ratio, heating of an ingot, hot rolling and blooming, two-stand continuous rolling, intermediate annealing, cold rolling and annealing of a finished product, so that the copper alloy band material is obtained. The preparation method has the beneficial effects that a unique separation and classification technology is adopted, impurity components are accurately controlled in the smelting process, the product totally meets the European Union RoHS standard, breakthrough of the copper alloy melt purification technology is realized, and the production technology of the copper plate band material is improved. In addition, beneficial elements contained in scrap copper are fully used, the raw material cost is lowered, and meanwhile upstream and downstream procedures of the industry chain are greatly reduced, so that short-process recycling of the scrap copper is realized.

Description

technical field [0001] The invention relates to the field of copper alloy preparation, in particular to a method for preparing an environment-friendly copper alloy strip. Background technique [0002] With the strengthening of social environmental protection awareness, people have gradually proposed environmental protection standards for copper strip products, especially with the promulgation of the EU RoHS directive, making copper strip products comply with RoHS standards and meeting environmental protection technical requirements is the current demand of copper strip manufacturers. solved puzzles. [0003] At present, the production process of copper strip products is mostly produced by electrolytic copper smelting. The specific process is: scrap copper-anode copper-cathode copper-smelting-casting billet-billet processing-heating-hot rolling blanking-cold rolling-surface cleaning and other processes, not only the production process is complicated, but also consumes a lot ...
