FIELD: processes and equipment for hot rolling of aluminum materials.
SUBSTANCE: method comprises steps of working roll surface during roll operation or after it with use of liquid jet supplied under pressure in range 50 - 250 MPa, preferably 70 - 150 MPa. Invention provided optimal condition for hot rolling of aluminum material due to cleaning roll surface without distortion of their surface micro-geometry and due to shortened idling periods of rolling equipment.
EFFECT: improved quality of restored surface of rolls, elimination of distortion of roll surface micro-relief.
