Definitions
- the invention relates to a method for roll lubrication, in particular for roll gap lubrication in a roll stand for rolled strip, wherein at least one first supply line water and at least one second supply line oil is supplied to at least one mixing element, wherein in the mixing element, the water and the oil are mixed and wherein the mixture of water and oil is fed to a spray element, with which the mixture is sprayed onto at least one roll of a roll stand. Furthermore, the invention relates to a device for roll lubrication, in particular for carrying out the method.
- Rolling mills often have roll gap lubrication systems installed. These are used to improve the surface quality of the work roll and strip and are part of the normal equipment of a modern rolling mill on which high-quality strips are to be produced.
- the effect of the lubrication will disappear or the results of the rolling gap lubrication will not be reproducible.
- the lubricity across the width of the tape is uneven, resulting in tape running problems.
- the cause of this is often the layered clogging of the pipes by saponification between the oil-water mixer and the spray nozzles. It also causes clogging of the small nozzles when particles detach from the wall and foul before the nozzle exit. It is a relatively large maintenance effort by mechanical cleaning of the system or temporary flushing of the piping between oil-water mixer and the nozzles and blown out of the nozzles necessary.
- JP 7016621 it is known to temporarily stop the oil supply and make a rinse of the nozzle with the water, which is otherwise used for the formation of the oil-water mixture.
- JP 56139213 provides that a cleaning solution can be introduced into the fluid lines as required to clean them.
- the invention is therefore based on the object to provide a method and an associated apparatus, with which it is possible or to ensure in a simplified and efficient manner that a continuous Waizz- splitting lubrication is ensured, over time a has consistent quality. This should be made possible in a simple and environmentally friendly manner. In addition, the process should not be adversely affected by this.
- the solution of this object by the invention according to the method is characterized in that at least one third supply line of the first or the second supply line and / or the mixing element at defined time intervals or depending on a process status of the rolling process hot water, steam or a chemical cleaning agent or the combination of two media is supplied.
- the supply of hot water or steam or other cleaning media is preferably carried out during the change of a roll of the rolling mill or at the end of a rolling program before a prolonged other plant downtime.
- the supplied hot water preferably has a temperature of at least 60 0 C.
- the hot water or water vapor are advantageously over a period of 2 to 15 minutes, respectively.
- a cleaning agent in particular a chemical cleaning agent, can also be added to the hot water or the steam in addition or at times, which is able to dissolve persistent oil residues.
- the supply of hot water or steam is preferably carried out with interrupted supply in the first or in the second supply line.
- a warning signal can be issued to prevent the risk of scalding personnel.
- the heating of the water or the generation of the water vapor can take place by means of an electric heating element, by means of an oil or gas heating or using solar energy (possibly only for support). The heating takes place during the rolling time and is available on request for cleaning.
- the inventive device for roll lubrication is characterized in that at least one third supply line is present, which is at one end fluidly connected to at least one of the first or second supply lines and / or the mixing element in connection and the other end with a supply unit for Hot water or steam is related.
- the supply unit for hot water or steam may have at least one electric heating element, an oil or gas heater or a solar heater.
- the supply unit (container) is advantageously thermally insulated.
- the at least third supply line is preferably also provided at least partially with a thermal insulation.
- the supply unit for hot water or water vapor can be coupled with the first supply line for water.
- valves are cleaned. For this purpose, all valves are opened and the cleaning is carried out over the entire width.
- the roll gap lubrication system can also be operated with a less good water quality and / or oil quality, which is more cost-effective and thus more economical overall. Furthermore, the conditions for the rolling gap lubrication always remain reproducible.
- FIG. 1 an embodiment of the invention is shown.
- the single figure shows schematically a device for roll gap lubrication in a roll stand for rolled strip, which is equipped with an integrated cleaning device.
- an apparatus is shown, with which a roll gap is lubricated with a water-oil mixture.
- a rolling stand 7 is shown, in which two work rolls 5 and 6 cooperate and form a roll gap, wherein the work rolls 5, 6 are supported by support rolls 12 and 13.
- a band 14 is shown schematically, which is rolled in the rolling mill 7.
- the supply line 1 supplies water from a source, not shown, while oil is supplied via the supply line 2. Both the water and the oil are supplied to mixing elements 3 in which the two fluids are mixed. The mixture is then passed to spray elements 4 in the form of spray bars and sprayed onto them on the rollers 5, 6.
- first supply lines 1 Wasserabsperrventile 15 are arranged, which can be actuated by a central controller 16 (indicated by the dashed lines).
- the oil flow in the second supply line 2 can be influenced by the controller 16.
- oil pumps 17 are arranged in the second supply line 2. These convey an oil flow to the mixing elements 3, whereby they build up their pressure against check valves 18.
- check valves 18 switchable on-off valves may be arranged which open when the oil pumps 17 are actuated.
- At least one third supply line 8 of the first or the second supply line 1, 2 and / or the mixing element 3 in defined intervals or depending on a process status of the rolling process, a cleaning medium such as hot water or steam is supplied.
- a supply unit 9 is provided for hot water or steam, which feeds their medium into the third supply line 8. Also in the third supply line 8 shut-off valves 19 are arranged, which can be actuated by the central controller 16. So that the temperature loss from the supply unit 9 to the mixing element 3 is as low as possible, a thermal insulation 11 is provided, which is placed around the line 8.
- the hot water or steam is generated in the supply unit 9, is basically arbitrary.
- an electric heating element 10 is provided.
- the water in the supply unit to temperatures between 60 and 95 0 C are heated.
- an automatic maintenance or cleaning of the Wafzspaltschmier- is provided.

- the area between the mixing element (oil-water mixer) 3 and the spray element (nozzle) 4 regularly with hot water or hot steam - optionally also with the addition of chemical cleaning agents - cleaned, which is typically a time of about 5 minutes to estimate ,
- the cleaning process is automatically after each use of a roll or a predetermined number of roll inserts (rolling programs) or after each use of the nip lubrication or a predetermined number of inserts carried out so that no ever-thickening saponification can occur, but the thin layer is removed again after each use.
- the cold water passes through the first supply line 1 and through the mixing elements 3 constantly and exits through the spray elements 4.
- the oil pumps 17 open by the pressure of the check valves 18, and the oil enters the mixing elements 3, mixes with the water and leaves as a dispersion of the spray bar 4.
- the dispersion is in the embodiment of the upper and lower work rolls 5, 6th or alternatively applied to the back-up rolls (spray bars not shown), whereby the oil reaches the roll gap.
- the cleaning procedure of the roll gap lubrication is started automatically. During roll or drum wiping this is possible without disturbing the operation.
- the choice of scaffolding to be cleaned is made by a process model depending in particular on the amount of oil used, on the activation of the rolling gap lubrication and on the cleaning time at the last standstill.
- the cleaning time is adjustable between 2 and 15 minutes.
- the oil pumps 17 are here or are already turned off here.
