Owing to a lack of gaugemeter and the variety of steel grades and standards in some plate mills, the long and shortterm selflearning models of rolling force based on gauge softmeasuring with high precision were brought up. The softmeasuring method and target value locked method were used in these models to confirm the actual exit gauge of passes, and thick layer division and exponential smoothing method were used to dispose the deformation resistance parameter, which could be calculated from the actual data of the rolling process. The correlative mathematical methods can also be adapted to selflearning with gaugemeter. The models were applied to the process control system of AGC (automatic gauge control) reconstruction on 2 800 mm finishing mill of Anyang steel and favorable effect was obtained.
