Abstract：The mechanical vibration device of the four link eccentric wheel for No.1 slab casting machine is not only high failure rate， but also can not adjust the amplitude online， it can not achieve the requirements of high vibration frequency 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 EtherCAT 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.
