The variables affecting the roll speed and the inherent relationships between them were analyzed. An optimization model of the roll speed for feedback correction of the temperature distribution in the weld pool and the roller speed correction model for the temperature feedback of the casting / mold interface were established. The casting speed of the automatic control system Detection and control. The on-line sampling by thermal imagers and infrared sensors can improve the accuracy and real-time of model control. Roller speed control optimization model aims at controlling the solidification end point to be stable at the optimal position, which is a good solution to jamming, cracking, And the problem of low yield and so on, roller speed control optimization model has greatly improved the stability of the system.
