The mould friction increases gradually before breakout.
拉漏前结晶器摩擦力逐渐增加。
The non-sinuous oscillation of the mold is used to reduce the mold friction force and stick type breakout, and to lower the oscillation frequency for high speed casting.
应用结晶器非正弦振动技术可以降低结晶器摩擦阻力，减少粘结性漏钢，同时大幅度降低高拉速时的结晶器振动频率。
A new method of predicting breakout and abnormal mould friction by the difference between measured value and predicted value is put forward. The result shows that the way is feasible.
提出通过拉坯阻力的实测值与预测值的差值预报拉坯阻力异常和漏钢的新方法，模拟结果表明此法可行。
