Abstract
A stand speed reference circuit is disclosed for providing speed reference signals to each of a plurality of selected stands in a continuous tandem rolling mill. U.s. pat. No. 3,852,983 to Cook for 'Work Strip Gauge Change During Rolling in a Tandem Rolling Mill' discloses a method for changing to a new gauge schedule without shutting down the mill, by using a precalculated multiplier to successively and progressively change the mill stand speeds of all the stands save the pivot stand, the speed of which remains constant at the previously scheduled rate. Interstand tension regulators between the stands automatically change the delivery gauge at the stand of entry of the gauge change point of the moving strip. The present disclosure provides an analog stand speed reference circuit to realize the Cook teaching without disturbing the mill by introducing spurious interstand tensions.
