Abstract：During casting, the driving force alarm will cause the emergency stop and even the billet accident. In order to prevent the occurrence of accidents, it usually adopts measures such as slow speed and strong cooling, but the speed reduction can cause cost waste, strong cooling can cause cracks and other quality defects. Both of them are difficult to meet production needs. Based on the comparative analysis of various parameters of the slab caster, the main reasons for the driving force alarm he abnormality of the roll gap, soft reduction model parameters, unreasonable cooling process, etc.By adjusting the secondary cooling technology, optimizing the model parameters and strengthening the fan- shaped section of roll gap maintenance light pressure area, the driving force can be significantly reduced, and to the purpose of eliminating the alarm can be achieved, thereby ensuring the stability of continuous casting.
