Abstract: The
law of strip surface roughness formation as well as its influence
factors is analyzed thoroughly by test and statistical research of
surface roughness of work roll and steel strip, the mathematics model to
predict strip surface roughness and the mathematics model to estimate
the transferring ratio are established by means of stepwise regression,
finally the model of roll surface roughness attenuation rule is
established. The models can be used to predict strip surface roughness,
arrange steel strip rolling order reasonably, decide the time of work
roll off mill and modify the calculation model of rolling force.
Key words: Cold strip Rolling force Surface roughness Stepwise
regression
