Production method of alloy copper bar

The invention belongs to the technical field of alloys and provides a production method of an alloy copper bar. The production method of the alloy copper bar specifically comprises the steps of melting, horizontal continuous casting, primary skin planing, primary drawing, secondary skin planing, secondary drawing, intermediate annealing, third-time skin planing of a finished bar blank and third-time drawing of the finished bar blank, and then the alloy copper bar is obtained. The alloy copper bar obtained by the preparation method has high tensile strength, ductility and density, and detectionshows that the tensile strength is 450 MPa or above and the ductility reaches 15% or above. The product is free of cracks, pores, burrs, fracture and interlayer, the surface of the product is smoothand flat, and the product is easy to cut and high in safety coefficient. 种合金铜棒的生产方法，属于合金技术领域。其具体包括熔融、水平连铸、第次刨皮、第次拉拔、第二次刨皮、第二次拉拔、中间退火、成品棒坯依次进行第三次刨皮和第三次拉拔，得到合金铜棒材。通过本发明得到的合金铜棒，具有高强度的抗拉性能和延伸率、致密度高，经检测，抗拉强度在450MPa以上，延伸率达到15%以上，产品无
