Definitions
- the present invention relates to a device for cleaning and drying rolling stands, in particular of rolling stands in a rolling train, wherein for changing the rolls a backup roll changing device is provided, which is retractable on rails in the rolling mill in the rolling mill.
- the rolling mode is often changed from wet-rolling to dry-rolling or to different emulsions or to pure rolling oils.
- the mill stand must be clean and dry in order to ensure the quality of the product to be rolled.
- the known automated cleaning devices provide permanently installed in the rolling mill piping with fixed cleaning nozzles for the cleaning medium, such as hot water, and permanently installed pipes for the dry air for subsequent drying of the rolling mill before.
- the cleaning medium such as hot water
- roller changing device nor the rails are part of the device according to the invention. This object is achieved by the features specified in claim 1.
- Advantageous embodiments of the invention are the subject of the dependent claims.
- the device according to the invention provides that the cleaning device, similar to the roller changing devices, is movable on the rails thereof and has a plurality of jet nozzles which can be aligned with the rolling stand for a liquid cleaning medium and blowing nozzles for a dry medium.
- the jet nozzles are designed as rotating nozzles. According to a particularly advantageous embodiment of the device according to the invention, the jet nozzles are arranged on or in a rotatable or pivotable nozzle head.
- jet nozzles are designed for spraying hot water.
- the hot water may be provided with or without a detergent additive. This depends on which rolling mode (using emulsions or rolling oils) the mill to be cleaned has been operated.
- the blowing nozzles are designed as slit nozzles.
- the dry medium can be hot or hot compressed air as needed.
- the slot nozzles can be combined into one or more rotating or pivoting blowing groups. It is provided that the air jet dries the rolling mill and the water drives in front of him until it runs into the scaffold bucket and is collected there.
- the blowing groups are, as essentially cylindrical, formed hollow bodies.
- the blowing nozzles are designed as rotating slot nozzles.
- the moisture can thus be driven evenly through the rotating slot nozzles from the framework to the drain, for example into the scaffolding trough.
- the jet nozzles and the blowing nozzles in their direction of action from top to bottom or from bottom to top - with respect to the rolling line - aligned.
- the coupling of the conduit system for the jet and blast nozzles to the respective supply sources during retraction of the backup roller changing device in the rolling stand is carried out automatically.
- the jet nozzles and the blowing nozzles with respect to their effect, discharge amount for the cleaning and drying medium and the rotational speed, and with respect to their distance from each other adjustable and position controlled.
- the jet nozzles and the blowing nozzles are part of a retractable into the rolling mill module, so that the cleaning and drying takes place successively by corresponding displacement of the module transverse to the rolling line.
- the individual functions cleaning and drying can also be fulfilled with two devices.
- the module is temporarily mounted on the back-up roll changing device.
- the module is temporarily introduced into the rolling mill using the roll changing device.
- the device according to the invention is provided to form the device according to the function as separate facilities for cleaning and drying.
- the device may be associated with additional devices, such as fans with supply channels and heat exchangers, as well as a hot water tank.
- FIG. 1 shows a schematic front view of the device according to the invention, transverse to the rolling line, with a
- FIG. 2 shows a schematic front view of the device according to the invention, transverse to the rolling line, during a blasting and blowing nozzle
- Fig. 1 and Fig. 2 show an embodiment of the device 10 according to the invention within a roll stand 1 1, which is part of a (not shown) rolling train. It is envisaged, the device 10, similar to a backup roller changing device (not shown), form on the rails 12 movable. The rails 12 on which the device 10, the roll stand 1 1 can be retracted are arranged transversely of the rolling line.
- the device 10 are associated with pressure lines 13, 13a, 13b and 13c.
- the pressure lines 13, 13a, 13b and 13c have at their respective free end 14 jet nozzles 15, 15a, 15b and 15c.
- a cleaning medium 16 for example, with surfactants added water, passed under high pressure.
- the cleaning medium 16 exits the jet nozzles 15, 15a, 15b and 15c.
- the jet nozzles 15, 15a and 15c are Preferably formedsstrotierend and are driven by the repulsive force of the cleaning medium 16 at the exit from the jet nozzles 15, 15 a, 15 b and 15 c.
- the device 10 can be moved transversely to the rolling line, as indicated by the arrows ( ⁇ ) in the roll stand 1. In order to precisely control and monitor the position of the device 10 in the roll stand 11, this is connected to a position control (not shown).
- the position control is adjustable so that the jet nozzles 15, 15a, 15b and 15c are more intensively operable and / or held in position over a longer period of time. As a result, difficultly accessible or heavily soiled areas of the roll stand 1 1 can be acted upon more intensively with the cleaning medium 16, so that a very good cleaning result is achieved.
- connection means 17, 17a, 17b and 17c are connected via connection means 17, 17a, 17b and 17c to a supply source (not shown), a mobile or stationary supply module, on the connection side 18 of the device 11.
- the connection is fully automatic, while the device 1 1, for example, on the rails 12 of a backup roll changing device, is retracted into the rolling stand 1.
- connection means 17, 17a, 17a and 17c By a single connecting means, in which the pressure lines 13, 13a, 13b and 13c are combined and supplied together via the common connecting means with the cleaning medium 16 ,
- This connection means is also connected on the connection side 18 to a supply source, a mobile or stationary supply module (not shown).
- the device 1 1 is assigned on the connection side 18 at least one further connection means 19, via which the device 1 1 is connected to a further supply source 20, a mobile or stationary supply module. can be tied.
- the device 1 1 has another Druck elaboratessys- system 21 on.
- the pressure line system 21 are assigned, in a substantially cylindrically shaped, blowing nozzles 22, 22a and 22b, 22c.
- the blowing nozzles 22, 22a and 22b, 22c are designed to be rotatable about their longitudinal axis.
- the blowing nozzles 22, 22a and 22b, 22c are designed as rotating and pivotable slot nozzles. Due to the possibility of rotation, all areas of the roll stand 1 1 can be blown evenly dry by means of a dry medium 24 fed into the pressure line system 21 via the supply module and the coupling 19.
- the dry medium 24 can be cold, warmed or high-temperature compressed air. Preferably generated by blowers.
- the cleaning medium 16 distributed by the spray heads 15, 15a, 15b and 15c is driven in front of it by the drying medium when retracting the device 11 into the roll stand 10 transversely to the rolling line (not shown).
- the cleaning medium 16 blown off and dripping off from the roll stand 11 is preferably collected and discharged in a collecting trough (not shown) assigned to the rolling stand 11.
- Reference numeral 10 Device 1 1 rolling stand 12 rails
