摘　　要：1号板坯铸机四连杆偏心轮机械振动装置不仅故障率较高,而且不能在线调整振幅,无法实现高振频、小振幅的浇铸要求,铸坯振痕较深,表面质量较差。针对四连杆偏心轮结晶器振动台存在的问题,以数字电动缸取代原四连杆偏心轮传动机构,通过Ether CAT技术实现四只数字电动缸的非正弦仿弧振动。经过2年多的生产实践证明,电动非正弦振动产生的振痕深度比较浅,对提高铸坯表面质量有明显改善。系统运行稳定,免维护,故障率低。还有效提高拉速,提升了铸机产能。The mechanical vibration device high failure rate, but also can not adjust the of the four link eccentric wheel for No amplitude online, it can not achieve the 1 slab casting machine is not only requirements of high vibration fre- quency and small amplitude casting, and the vibration marks of the billet is deeper, the surface quality is poor. In view of the problems of the four link eccentric wheel mold vibration, a digital electric actuator repalced the original four link eccentric wheel mechanism, realizing the non-sinusoidal imitation arc vibration of four digital electric actuator by Ether- CAT technology. Through more than 2 years of production, it has proved that the depth of vibration marks produced by the electric non sinusoidal vibration system and the surface quality of the slabimproved obviously. The system is stable, non maintenance and low failure rate. It also effectively improves the casting speed and production capacity of CCM.
