FIELD: process engineering.
SUBSTANCE: quarto rolling mill bearing roll assy comprises roll pads with supports between which equaliser is arranged. Fast and reliable replacement of worn-out rolling tools are ensured by making taper holes at working toll ends at existing rolling equipment. Working roll supports are composed of cones revolving about their axes to displace axially and about their axes and located in appropriate taper bores of working rolls.
EFFECT: easier operation of four-roll rolling mills.
