电子计算机对挤压过程控制的实际应用要求对挤压过程进行深入的予备性研究,以求得最佳的控制。为此目的,重要的是确定哪一种挤压工艺参数影响挤压质量和生产效率。确定每一个所研究的工艺参数对挤压质量和生产效率的影响程度也是很重要的。应该优先考虑的基本工艺参数是金属制品从孔流出时的温度。一方面,这一温度依赖于挤压速度;另一方面,它又决定了挤压产品的质量。众所周知,对于任何一种铝合金都必须确定它的临界温度,挤压时如果超过这一
The practical application of computer control of extrusion process requires in-depth preparatory study of the extrusion process in order to obtain the best control. For this purpose, it is important to determine which extrusion process parameters affect extrusion quality and production efficiency. It is also important to determine the extent to which each of the process parameters studied influences extrusion quality and production efficiency. The basic process parameters that should be prioritized are the temperature at which the metal product flows out of the orifice. On the one hand, this temperature depends on the extrusion speed; on the other hand, it determines the quality of the extruded product. As we all know, for any kind of aluminum alloy must determine its critical temperature, squeeze if more than this
