APPARATUS FOR REGULATING INTER-STAND TENSION OF STRIP IN CONTINUOUS COLD ROLLING MILL Russian patent published in 2004 - IPC

Abstract RU 2235613 C2

FIELD: plastic working of metals.

SUBSTANCE: apparatus for regulating inter-stand tension of strip in continuous cold rolling mill having screw-down mechanisms of stands, devices for measuring inter-stand tension of strip and rolling speed meter includes IP-unit. Inlet of screw-down mechanisms of any stand is connected with outlet of strip tension measuring device through IP-unit. Proportional and integral inlets of IP-unit are connected with outlet of strip tension measuring device through multipliers. Second inlets of multipliers through their own non-linear circuits are connected with meter of rolling speed.

EFFECT: optimal distribution of action of integral and proportional circuits for regulating inter-stand tension of strip.
