Cleaning device and method for removing a lubricant from the rolls of a roll stand

Abstract

A cleaning device and method remove a lubricant from the rolls of a roll stand. To achieve economical and efficient cleaning of the rolls, the cleaning device includes at least one ultrasonic generator for generating ultrasonic waves, the ultrasonic waves being routed to the surface of the rolls by cleaning water; and a supply line for the cleaning water. The supply line is a branch of a cooling water circuit for the roll stand, enabling the water consumption for the roll stand to be kept constant during the cleaning phase. The water is merely redistributed in that a portion of the cooling water is supplied to the cleaning device. This creates the advantage of the roll temperature rising slightly, with the result that the cleaning performance is supported by the higher roll temperature at which the lubricant is better released from the surface of the roll.
