Abstract
A descaler for removing scale from steel billet before rolling of the steel billet. The descaler has a plurality of steel wire brush units each being constituted by an elongated supporting member and a multiplicity of steel wires arranged densely along the length of the supporting member and attached to the same. The steel wire brush units are loosely mounted on a rotary drum with their supporting members extending in parallel with the axis of the drum for limited radial movement and circumferential rocking movement with respect to the rotary drum. In operation of the descaler, the steel wire brush units are projected radially outwardly by the action of the centrifugal force to strongly strike and hit the billet surface to promote the removal of the scale. Since the flexing of each wire is resisted by the bundle of densely arranged steel wires, the breakage of the steel wires is suppresed to ensure a longer life of the descaler.
