四、冷轧机操作自动控制冷轧机的操作,是指冷轧机在整个轧制过程(由上带卷的全部过程)所必须的有次序的一系列设备动作。这些动作如果只由人工操作控制,则为手动操作;这些动作如果由自动控制系统和装备操作,则为冷轧机操作自动控制,也叫冷轧机操作自动化。冷轧机操作自动化包括下述内容:自动开卷、自动穿带、焊缝自动减速、带钢抛尾自动减速和停车、自动卸卷和自动换辊等。 Fourth, cold rolling mill operation automatic control Cold rolling mill operation, refers to the cold rolling mill throughout the rolling process (by the whole process with the volume) must order a series of equipment action. These actions are manual operations if they are controlled only by manual operation; these operations are automatically controlled for cold mill operation, also called cold mill operation automation, if operated by an automatic control system and equipment. Automatization of cold rolling mill operations include the following: automatic unwinding, automatic threading, automatic decelerating of welds, automatic decelerating and stopping of strip tailgating, automatic unwinding and automatic roll changing.
