On the basis of massive and long-term experimental and industrial measurements of the torque in the drive lines of cages of continuous wide-strip hot rolling mills, a correlation between the maximum dynamic moment during strip gripping by the rolls and the moment in the steady state of rolling has been established. As a result of the random effect of technological disturbances and gaps according to the measurement data, correlation fields of static and maximum dynamic moment values are formed: the greater the static moment, the greater the dynamic moment. This dependence was not revealed on a small array of measurements. The fields are approximated by a linear dependence and have a number of features that can be used to assess the stability of the rolling process and the condition of the equipment, calculate its resource, determine the most "heavy" assortment under load conditions, and adjust the crimping regimes.
