Optimization of AGC controling methods of thickness for finishing rolling of hot strip mill
To improve the production stability and the qualified rate of thickness for the hot strip mill,some process and control parameters of the AGC system of thickness of the finishing mill were optimized.The adjusting clip and the speed for AGC system of the finishing rolling were established according to the thickness range.The adjustment pattern of AGC system for the deep-drawing product series was optimized.The locking function of AGC system for the tail of strip steel was developed.Through optimizing,the control precision of AGC system of the finishing rolling was improved and the production stability of finishing rolling at mixed rolling was increased.The qualified rate of thickness for hot rolling mill production came up to above 99.5 ％ averagely.
