METHOD OF ADJUSTMENT FOR COLD ROLLING MILL WITH FULL CONTROL OF MASS FLOW Russian patent published in 2013 - IPC B21B37/16 

FIELD: process engineering.

SUBSTANCE: proposed method is intended for adjusting parameters of cold rolling mill with several strip rolling stands 2 and strip feeder 3 mounted ahead of first mill stand 2-1. Efficient adjustment with advance factor allowed for is ensured by zero preset rpm (v-0*) is fed to strip feeder 3, strip is fed to first stand (2-1) is fed at first rpm (v-0) corresponding to zero preset rpm (v-0*), first preset rolls rpm (v-1*) is fed to said first stand (2-1), said rolls (7-1) run at first actual rpm (v-1). First thickness gage (4-1) is arranged between first and the next rolling stand (2-2) to measure strip actual thickness (d-1) to define, on the basis of the latter and first preset thickness (d-1*), the first main output signal to be used for make the first, but not the preset zero rpm (v-1*) so that first actual thickness (d-1) of cold strip (1) complies with the first preset thickness (d-1*) of cold strip (1). Zero device (4-0) is arranged between strip feeder 3 and first and (2-1) to measure actual zero thickness (d-0) of cold strip (1), then zero straight adjustment gage (9-0) is used to set preset zero rpm (v-0*) so that its product with zero actual thickness (d-0) is set to preset mass flow.

EFFECT: adjustment of rolling parameters.
