METHOD OF ROLLING MILL LAYOUT ALTERATION AND MODERNISED ROLLING MILL INTENDED FOR IMPLEMENTATION OF THIS METHOD Russian patent published in 2008 - IPC B21B13/00 

FIELD: technological processes.

SUBSTANCE: invention is related to plastic metal working, in particular, for rolling mill layout. Rolling mill contains at least two working rollers and two support rollers, facilities for applying forces for rollers convergence and two systems of hydraulic power cylinders for provision of bend of at least two working rollers. By changing position of rollers installed between the support rollers, rolling mill layout "quarto" is changed into "sexto" and back with application of one and the same rolling mill is used, the same facilities for applying forces for rollers convergence and forces for provision of their bend and the same type of support rollers. Working rollers of the largest diameter are used in "quarto" layout as working rollers, and in "sexto" layout - as intermediate rollers that are installed between every support roller that remains in its place, and roller of smallest diameter that is used as working roller.
