- a skin pass mill typically consists of a pair of work rolls which are in direct contact with the strip surface and a pair of backup rolls (a so-called quarto backbone) or a system of multiple back-up rolls (eg six-high skin pass mill or other systems) which stabilize the work rolls and drive.
- baubles or “sediment dust”
- This layer of dirt can flake off or be transferred to the work rolls, resulting in impressions on the strip surface.
- the device according to the invention or the method according to the invention serves for the continuous cleaning of rolls by a combined suction-blowing device. By a permanent blowing of the roll surface, the abrasion occurring during rolling is continuously removed, thus preventing the formation of a dirt layer on the roll surface. Combined with integrated extraction, the dust can be removed directly.
- the hood and the effective range of the injected gas or fluid flow covers the entire working width of the roller to be cleaned, which corresponds at least to the width of the metal strip.
- the blast air is therefore ideally irradiated via a slot nozzle or a nozzle bar of a plurality of individual nozzles, which extend in the width direction of the roller at least over the width of the strip material.
- a gas air or compressed air is ideally used from an economic point of view.
- the incoming air flow must be dimensioned so that it comes to a detachment of adhering to the roll surface particles.
- the nozzle shape is of particular importance.
- the nozzle is designed in one embodiment in the form of a venturi, which can increase the amount or speed of the gas stream.
- the geometry of the nozzle is designed such that by using the Coanda effect, the gas stream is directed in a concentrated manner onto the surface.
- the flow in the hood must be designed in such a way that no so-called dead zones occur within the hood, which favor deposition of the skin-pass dust on the wall of the suction hood.
- dead zones occur within the hood, which favor deposition of the skin-pass dust on the wall of the suction hood.
- the suction of the hood must be adjusted so that the sedative dust can be completely removed from the hood.
- Supply and exhaust air must be adjusted so that no pressure in the hood is created, which hurls particles from the gap between the hood and roll surface.
- At least one nozzle is provided, which directs a fluid flow to the surface of the roller, and at least one suction channel is provided.
- the at least one nozzle and the at least one suction channel are arranged in a common hood, wherein the hood covers a part of the circumference of the roller.
- the suction power i. the volume flow of the at least one suction channel arranged in the hood is greater than the fluid flow introduced by means of the at least one nozzle arranged in the hood. In a preferred embodiment, therefore, the volume flow of the exhaust air is adjusted by 5% to 50% greater than the injected gas flow.
- the at least one nozzle covers at least one of the width of the strip-shaped material corresponding width of the roller.
- the at least one nozzle is directed at an angle of +/- 45 °, preferably +/- 10 °, in particular 0 °, with respect to the vertical on the surface of the roller and at a distance of less than 50mm, preferably 1 mm to 30mm, arranged away from the surface of the roller.
- the at least one nozzle is designed as a slot nozzle or as a nozzle beam with a plurality of individual nozzles arranged next to one another, wherein the individual nozzles themselves can be point-shaped or slot-shaped.
- the maximum nozzle spacing depends on the nozzle opening and shape and the resulting flow velocity. It is about 50mm for a nozzle with a 4mm opening. A particularly good cleaning effect is at
- Achieved nozzle distances which are about 1-30 mm from the roll surface.
- means are provided in the at least one nozzle or its feed line in order to introduce at least temporarily abrasive particles into the gas stream. For example, from the field of beam processing known particles based on corundum.
- roller diameter the cleaning device according to the invention is adjustably mounted on the rolling stand.
- At least one further suction channel is provided, which preferably extends over a width which corresponds to the width of the band-shaped material and is arranged outside the hood in the region of the contact point, preferably in the exit direction, with an adjacent roll or the band-shaped material.
- Fig. 1 shows a cleaning device according to the invention seen in the direction of the roll width.
- Fig. 2 shows a further cleaning device according to the invention seen from the direction of the roll surface.
