Purple Miscellaneous Copper Directly Bright Copper Rod Production Process Design And Refining Process Exploration Research

According to meticulous market research and designing argument, cooper scrap was used as materials in this designment, which produced with the well-developed Continuous Casting and Rolling (CCR) technics, a suite of new patent technic and equipments was used for copper melting and refining, the cooper rod was produced with well quality, and all performance index reach the GB standards of China. In the designment, perfect bath analysis and production test equipment were chosen for product quality control. For the complex off-gas composition generated in the process of copper scrap refining, innovative processes, such as afterburning, quick cooling, acid removing, adsorption, dust removing, can get rid of injurant in the gas, which could not only make full use of heat energy, but also meet the emission control regulations without generating of dioxins.As cooper scrap refining techniques exploring and practicing, a system of measurements was developed for quality control in production process. Rear earth (RE) refining was innovatively introduced in copper rod production, which could increase refining efficiency and improve the conductibility and mechanical property. The effect and its mechanism of the RE in refining process were discussed, the manner, the time and the dose in process of adding RE to bath was ascertained.After test of production practice, the process design has been proved to be successful with excellent economic performance and social efficiency. rod is taking cooper scrap as raw material, which conforms to sustainable development stratagem and industry policy in China. The line is featured with high price performance ratio, simple structure, easy to maintain, continues process, well-developed computer monitoring System, inline testing. The technic and equipment selection is reasonable, which fills several blank of this field in China. The rod produced with RE refining technic and equipment in this designment shows great properties with the conductivity more than100%IACS, elongation percentage more than37%, failure in torsion test not less than45circle, which is popular with wire drawing enterprise downstream.The implementation of this project will construct a resource saving and environment friendly Industrial demonstration base, which may greatly promote the industry’s development.
