METHOD FOR CONTROLLING COOLING CONDITIONS OF ROLLED PIECES Russian patent published in 2002 - IPC

FIELD: rolled stock production, namely controlling hot and(or) cold rolling processes. SUBSTANCE: method comprises steps of measuring temperature of rolled piece and parameters of its movement; comparing measured temperature with its preset normalized value; correcting flowrate of cooling agent by regulating number of operating cooling sections; before starting rolling process adjusting cooling system according to measurement results for previous rolled piece of the same or almost the same steel and grade. EFFECT: enhanced uniformity of physico-mechanical properties along rolled piece independently upon its grade.
