FIELD: metallurgy.
SUBSTANCE: method includes removal of the cover from the bed foundation, its 180° rotation in space, replacement of cartridges with rolls, mounting or dismantling of the top and lower ruler holders with the subsequent installation of the cover on the bed foundation. The top housing is rotated in space by 180° around the vertical axis passing through the cover centre of gravity by means of the rack bearing the shaft with two bearing supports and the electromechanical drive; on the shaft the console forked beam is fixed.
EFFECT: decrease of labour input of the operation and increase of productivity of the rolling unit in general.
