Abstract 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.
