Definitions
- the invention relates to a method for lubricating rolls, in particular of work rolls of a roll stand and rolled rolled between them and rolled strip, wherein a lubricant-gas mixture, a lubricant-water-gas mixture, a lubricant-water mixture and / or a grease-medium mixture is applied to the rollers or the rolled strip on the upstream side.
- the rolling stand comprises a plurality of mutually supporting rollers, such as a work roll, which comes directly into contact with the rolling stock and in turn rolls on a usually larger support roll or an intermediate roll.
- Roll-gap lubrication systems are integrated in many hot rolling mills for rolling a metal strip. These are used to improve the surface quality of the work roll and the strip and now belong to the usual equipment of a rolling mill on which high-quality tapes are to be produced.
- the system in which water as a carrier medium is mixed together with oil and applied to the rolled strip or the working or backup roll is widely used.
- lubrication is common.
- lubricant is applied to the rolled strip and / or the work roll and / or injected into the roll gap.
- the mixture of oil and water takes place far away from the mill stand.
- an emulsion is used, which is prepared in a complex process in a circulation system, cleaned and fed back to the lubrication system.
- BESTATIGUNGSKOPIE WO 03 002277 A1 discloses a method and a device for cooling and / or lubricating rolls, in particular of the work rolls, of a roll stand, in which water in the form of spray jets as cooling medium and oil, an oil-air mixture, an oil-water mixture, an oil-water-air mixture or fat mixtures are used as a lubricant.
- a combined use of supercooling of the belt and roll surface and the roller lubrication on the scaffold inlet side is proposed, in which the two media - water and lubricant - the rolls or the strip fed separately and to different application sites of the roll surface be applied. Separate feeds to the spray bars are provided for water and the lubricant respectively.
- this object is achieved in the aforementioned method in that the mixture is processed by means of at least one mixing device in the area in front of the rolling stand.
- the aim of the new lubrication method is to produce the lubricant shortly before use or application, similar to hot rolling, and thus to avoid expensive preparation in a closed circuit.
- it also has the goal to minimize the amount of lubricant used.
- the same goal also exists when using the lubricating method according to the invention during hot rolling. When reducing the amount of lubricant at the same time the lubricating effect should be optimized and the lubrication effect be adjustable.
- the lubricants used are, for example, oil-water dispersions, oil-water emulsions, oil-free water-miscible lubricants, oil-air mixtures or oil-water-air mixtures.
- the media can be sprayed in 2-, 3-, or 4-fluid nozzles.
- oil and water are mixed with air just before spraying. This way, even the smallest amounts of oil can be applied to the roll surfaces or the rolled strip.
- mixing oil and water has the advantage, unlike using pure oil, that there is no risk of fire.
- the advantage of the new lubrication process in the cold rolling process is that the oil concentration in the lubricant can be changed very quickly and flexibly. This allows the lubricant to be optimally adjusted to different materials to be rolled, to different belt speeds, to changing approvals and to the respective rolling stand. Furthermore, different oils and lubricating media for different applications can be provided.
- water and at least one lubricant are conveyed via separate supply lines to a mixer and mixed therein to form a water-lubricant dispersion or emulsion.

- the mixing operation is realized by mixing the at least one lubricant and the gas in a mixing block and then adding water to 2-component mixing nozzles.
- the water can be mixed outside each of an inner nozzle tube of the two-component mixing nozzles.
- the at least one lubricant is mixed with the gas, in particular in a mixing block, and sprayed by means of nozzles on at least one of the rollers and / or the rolled strip, while the side of the nozzle water is sprayed.
