Nonsinusoidal oscillation of continuous casting mold is one of the key technologies for high speed casting with high quality. In this paper, the determination of a nonsinusoidal oscillation profile and principle of selecting correspondent parameters were presented, and the effects of primary oscillation parameters on casting process were discussed. Moreover, the relation between casting speed and primary oscillation parameters for the synchro controll was built up, that will be helpful for making better use of nonsinusoidal oscillation to fulfill the request of continuous casting production.
