| Abstract: | Load distribution of tandem cold mill process control was calculated directly by Newton Raphson iterative calculation. The accuracy,time and stability of this method were discussed. The algorithm for initial value calculations and simplified calculation for Jaccobi matrix were established. The correction calculation for each stand reduction which had been obtained by load distribution calculation, was carriedout in order to avoid the slip phenomenon of No.5 stand because of the increase of rolling length. The control method has been put in use being very good. For actual on line control of tandem cold mill and the accuracy and reliability have been proved. |
