Abstract Non-sinusoidal oscillation factor was introduced into non-sinusoidal oscillation to make it take on the virtues of optimum mode, so the determination of it is very important to actualizing high speed casting with high quality. Combined with actual data and a non-sinusoidal oscillation profile with virtues of optimum mode, oscillation process parameters and friction force in mold were analyzed, rational factors at 1.8 m•min-1 and 2.0 m•min-1 casting speed adopted this profile were given, and the rule of factor change when the casting speed increased was also discussed. The results show that the rational factor at 1.8 m•min-1 and 2.0 m•min-1 casting speed was 0.2, it is consistent with practical system, under the situation of frequency and amplitude invariable, the factor should be increased to 0.25 to ameliorate oscillation effect real time when casting speed enhanced to 2.2 m•min-1 from 2.0 m•min-1.
