Abstract: The method of controlling a velocity dependent factor of strip material being processed in a mill includes the steps of simultaneously determining the apparent velocity of material prior to, between and subsequent to spaced apart work rolls. Input slip is determined by comparing the apparent input velocity with the apparent work roll velocity, and output slip is determined by comparing the apparent output velocity with the apparent work roll velocity. A velocity dependent factor is calculated in response to a comparison of input slip and output slip. The calculated factor is compared with a previously calculated factor and a derived factor is calculated when the calculated factor exceeds the previously calculated factor by more than the selected amount and an adaptive factor used to calculate the derived factor is calculated when the calculated factor does not exceed the previously calculated factor by the selected amount. A selected number of the calculated and/or derived factors are averaged and the divergence between the averaged factor and a target factor is used to adjust the spacing between the work rolls.
