所谓“超高速挤压”,通常是指金属流出速度在100米/秒以上的塑性变形。用这种方法生产铝合金材料,可以提高生产效率几倍,甚至几十倍。但也带来了一系列的困难,除须克服设备及工具材料等重大技术问题外,在工艺方面的关键问题,则是润滑技术。因为,在超高速挤压时,金属的塑性变形规律要发生变 The so-called “super-high-speed extrusion,” usually refers to the metal outflow rate of 100 m / s or more plastic deformation. Using this method of production of aluminum alloy materials, can improve production efficiency several times, or even dozens of times. But it also brought a series of difficulties. In addition to overcoming major technical problems such as equipment and tool materials, the key issue in the process was lubrication technology. Because, in the ultra-high-speed extrusion, the plastic deformation of the metal to be changed
