CONTINUOUS ROLLING MILL TUNING METHOD Russian patent published in 2005 - IPC

FIELD: processes for making rolled products such as simple and shaped sections, possibly in continuous rolling mills.

SUBSTANCE: method comprises steps of measuring (at rolling process) size of rolled strip along its length and detecting revolution number of rolls in stands; correcting preset inter-roll gaps and revolution numbers of rolls in stands; simulating parameters of rolling next strip on base of previous data of rolling mode of section; rolling next strip and simultaneously measuring its size and revolution number of rolls in stands; after finally setting inter-roll gaps and roll revolution numbers, evaluating specific consumption of electric energy in stand groups for reducing metal; according to set optimization algorithm, selecting optimal speed mode with minimum specific electric energy consumption.

EFFECT: minimized specific electric energy consumption, possibility for correcting sped mode at temperature fluctuation and at change of physical and mechanical properties of pieces to be rolled next from initial values.
