electrode paste soft broken and hard broken are serious accident in application.
The key factor in using electrode paste is that, consumption rate should match with baking rate.
The reasons for soft broken:
The baking rate is slower than consumption rate. The electrodes running speed is too fast to be baked completely, which make the electrode can not undertake the end stretch and side impact. And then the electrodes break.
The reasons for hard broken:
The electrode paste strength is not enough after being baked.
