摘要
为提高非晶薄带的生产效率,非晶合金薄带生产和X光测厚仪配置,设计了基于PLC的板型闭环控制系统。结果表明,采用X光测厚仪在线检测薄带厚度,根据厚度反馈控制喷嘴包伺服系统进行位置调节,使喷嘴包和冷却辊之间的间距保持动态稳定。同时,设计板型显示器在线显示非晶薄带板型及厚度,实现人机交互。在薄带开始制备时,采用梯度反馈控制策略逐步调整辊嘴间距,可以有效防止超调或者振荡。该系统满足精度和实时性要求,提高了非晶薄带长度和宽度方向的厚度一致性。
In order to improve the production efficiency of the amorphous thin ribbons, a plate-type closed-loop control system based on PLC was designed which was based on the production characteristics of the amorphous ribbons and the X-ray thickness gauge. The results show that the system include X-ray thickness gauge online detection of thin thickness, according to the thickness of the feedback control nozzle package which can adjust the position servo system, and it could keep the nozzle cooling roller spacing between package and dynamic stability. At the same time, the design panel displays the amorphous ribbons and thickness, and realizes humaa-computer interaction. The gradient feedback control strategy is used to adjust the spacing of the roll nozzle gradually when the ribbons begin to be prepared, which can effectively prevent overshoot or oscillation. The system satisfies the requirement of precision and real-time, and it improves the thickness uniformity of the length and width direction of the amorphous ribbons.
