Based on solidification theory and analysis of process of Aluminum alloy Direct Chill casting, the control system of DC casting for big size billet has been designed. For improving the quality of billet-optimized control strategy of cooling water must be determined to eliminate the instability of the traditional feedforward control, PID control and cascade control have been introduced.
