SPRAYING METHOD AND DEVICE FOR A ROLLING PLANT

摘要

A spraying method and device for a plant for rolling a strip, the plant having at least one rolling stand. The device includes: a pair of working rolls between which the strip runs; a plane perpendicular to the running direction of the strip; at least one pair of supporting rolls for the working rolls; two pairs of bearing rolls, each of the pairs having the rolls thereof substantially symmetrically arranged on either side of the working rolls in a plane substantially parallel to the strip so as to transfer, to the working rolls, a force for maintaining the working rolls in a predetermined position relative to the supporting roll; a support for the bearing rolls in the form of two rows including a plurality of bearing rollers mounted side by side; one or more nozzle systems for spraying at least a portion of the strip and at least a portion of the rolls. At least one of the nozzle systems is capable of directly spraying at least a portion of the working rolls on either side of the plane that is perpendicular to the running direction of the strip.
