摘要
攀钢2号板坯连铸机引进了国外某公司的结晶器液压振动装置INMO,INMO在运行过程中陆续暴露出偏移位颤振、偏振及导向轮故障率高、更换时间长等问题,严重制约了2号板坯连铸机的产品质量和产能发挥。通过探索与国内设计单位合作,有针对性地对液压缸、伺服阀、导向装置及电控系统进行了优化设计,同时在程序设计时采用开环和闭环相结合的控制策略,有效避免了伺服系统出现振荡现象,对2号板坯非正弦振动装置成功实施了改造。
The No.2 slab continuous casting machine mould hydraulic oscillation device of INMO is introduced from a foreign company. INMO in the operation process has exposed the offset a flutter,polarization and guide wheel,high failure rate,replacement time and other issues. It has seriously restricted product quality and capacity. By exploring cooperation with domestic design units,optimizing the design of hydraulic cylinder,servo valve,guide device and electric control system and applying the control strategy combining the open and closed loop in the program,the oscillation phenomenon of servo system has been effectively avoided. The transformation of No.2 slab nonsinusoidal vibration device has been successfully implemented.
