| 7. | The oscillation of continuous casting mold is an important factor that has effect on casting production . the oscillation of continuous casting mold has experienced four kinds : synchronisiru negative slide > . sinusoidal and non - sinusoidal oscillation
连铸结晶器的振动是影响连铸生产的重要因素，它主要分为四种方式：同步式振动、负滑动式振动，正弦振动和非正弦振动。 |
| 8. | Non - sinusoidal oscillation has the characters that the upward time of the continuous casting mold is longer than the downward time . it can reduce the friction between the mold wall and the strand surface , and prevents the strand from leaking and cracking , it can also improve the surface quality of slabs . it is the main development of continuous casting mold in the future
其中非正弦振动具有上升运动时间比下降运动时间长的特点，能减小结晶器与坯壳之间的摩擦力，防止坯壳的拉漏和拉裂，改善钢坯的表面质量，是今后连铸结晶器振动发展的主要方向。 |
