摘　　要：连续挤压技术是19世纪70年代在国际上提出的一种塑性加工新方法。与传统挤压方法相比,其具有节能、材料利用率高、自动化生产、可制造大长度产品、占地面积小、节约劳动成本等优点,被广泛应用于有色金属工业界,尤其是铜、铝及其合金制造领域,并相继淘汰了许多传统工艺。在简述连续挤压和连续包覆技术的工作原理基础上,介绍了连续挤压技术从力学理论、数值模拟到关键技术与设备开发的发展情况及现状。重点介绍了应用连续挤压和包覆技术制造铜扁线、铜排铜板带、制冷用铝管、铝包钢复合线、电缆护套等典型产品的技术特点及应用现状。最后从未来市场的角度分析了连续挤压技术的发展趋势。The continuous extrusion technology is a new plastic processing method developed in the 1970s. Compared with the traditional extrusion technology, it has a variety of advantages, such as energy saving, high material utilization, automated production, no limitation of product length, smaller floor area, saving labor cost and so on. It is widely used in nonferrous metal industry, especially copper, aluminum and their alloy manufacturing. As a result, many traditional processes are knocked out. This paper introduces continuous extrusion technology development and the status from me- chanics theory, numerical simulation to key technologies and equipments development based on the theory of the continu- ous extrusion and continuous cladding technology. It focuses on the applications for copper strip, copper bus bar, alumi- num tube, aluminum cladding steel wire and cable sheath. Finally standing on the angle of future market, this paper ana- lyses the development trend of the continuous extrusion technology.
