ROLLING PLANT, AND CONTROL METHOD OF ROLLING PLANT OPERATION Russian patent published in 2012 - IPC B21B37/48 

FIELD: metallurgy.

SUBSTANCE: invention refers to rolling plant, and namely to tandem rolling plant for cold-rolled strip, with several roll stands located in one rolling mill; besides, in production direction (P) of metal strip the first roll stand is made as the drive roll stand and serves as an inlet for continuous roll stand section in which considerable reduction of metal strip thickness is performed, and due to the appropriate control of drive roll stand there can be achieved the increase in mechanical stress at metal strip inlet. There also described is control method of rolling plant, and namely tandem rolling plant for production of metal strip, in which the first roll stand is controlled in production direction (P) of metal strip as drive roll stand, in which by means of drive roll stand there performed is considerable increased in mechanical stress at metal strip inlet without considerable reduction of metal strip thickness.

EFFECT: providing the distribution of single reductions in compliance with design features of an individual roll stand in rolling mill.
