问题与任务用卧式挤压机挤压铝合金型材是普遍的加工方法。早在几个世纪之前,这种工艺(1)就已经成熟。而且当时还可以成功地用来加工难挤压材料。尽管如此,在某些挤压技术范围里还存在不少问题,特别是对工序的监视与控制,没有得以足够地 Problems and Tasks Horizontal extruders extruding aluminum profiles are common processing methods. As early as a few centuries ago, this process (1) has matured. It was also successfully used to make difficult-to-extrude materials. In spite of this, there are still some problems in some extrusion technologies, especially the monitoring and control of processes, which are not enough
