摘要：
To improve the slab quality,a kind of non-sinusoidal oscillation technique of mold driven by elliptic gears was developed.The waveform functions of non-sinusoidal oscillation were determined,and the calculation method and curves of technological parameters for non-sinusoidal oscillation were given.At the case of waveform deviation factorαequal to 0.31and oscillation amplitude hequal to±2.7mm,the relationship between oscillation frequency and casting speed is determined,and the technological parameters for non-sinusoidal oscillation are calculated.The testing results of industrial application indicated that this technique could not only improve the slab surface quality,but also reduce the steel breakout.
