Abstract
A system and method for achieving an optimum interstand strip tension providing substantially equal loading of adjacent stands of a tandem rolling mill where such optimum tension is determined by the expression ##EQU1## where A1 and B1 are, respectively, the load ratio intercept and the slope of the load ratio versus interstand tension function for a first mill rolling stand, and A2 and B2 are, respectively, the load ratio intercept and the slope of the load ratio versus interstand tension function for an adjacent second mill rolling stand, and whereby the rolling capacity of the mill is substantially fully utilized.
