A laser descaling device and process includes a first laser sending a ray to the product to be descaled, reflected rays being intercepted by sensors that send collected information into a processing unit that calculates the absorption of the ray by the surface of the product, deduces the emissivity of the oxidized surface in the direction of the reflected rays, and correlates this emissivity with reference information prerecorded inside the processing unit; a second laser sends a ray onto the surface of the product, the spots of the rays covering the entire surface to be descaled, the second laser being controlled by a control unit receiving information provided by the processing unit making it possible to determine the operating parameters to be imposed on the second laser to obtain the descaling of the surface of the product, compared with experimental results prerecorded in the control unit.

The invention relates to a steel wire descaling device. The device includes one or more first steel wire descalers and one or more second steel wire descalers. A descaling roller for removing an oxide scale from a surface of a steel wire is disposed on each of the first steel wire descaler and the second steel wire descaler. The descaling roller of the first steel wire descaler is disposed inclinedly, the descaling roller of the second steel wire descaler is disposed horizontally. By inclinedly brushing the steel wire by using the first steel wire descaler and flatly brushing the steel wire by using the second steel wire descaler, the combination of flat brushing and inclined brushing allows oxide scales to be from steel wires without a blind spot.

A device for the mechanical cleaning of wire rods for the production of drawn metallic wires includes a pair of elements supported by a shaft, each element having a truncated-conical body and a flat disk that closes the truncated-conical body, defining an internal annular space that contains the steel wool. The flat disk has openings that are shaped as a slot. The two elements being disposed one in front of the other, with a space between the two flat disks. During operation, by rapid rotation of the shaft, the steel wool expands under the effect of a centrifugal force in radial direction, thus creating an axial thrust component on the steel wool such that the steel wool escapes partially and elastically from the openings of the flat disks so that the steel wool brushes against the surface of the wire rod in transit in the space between the two elements.
