The mould friction increases gradually before breakout.

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.
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.
