Definitions
- the invention relates to a method and a device for cooling and / or lubricating rolls and / or rolling stock, in which, on the one hand, a cooling medium is applied to the rolls from several nozzles / nozzle rows and, on the other hand, a base oil is applied to the rolling stock in front of the roll gap, whereby the nozzles / nozzle rows can be set up individually and independently of one another.
- the lubricating components applied locally to strips of the strip to be rolled are intended to locally reduce the rolling force and thus also to reduce the local flattening of the rolls and also the local final thickness of the strip. Furthermore, flatness errors of the rolled strip are to be avoided by locally reducing the heat of friction of the rolls in a manner comparable to zone cooling.
- a cooling liquid is sprayed on in a narrow area that extends directly in front of the roll gap, both the jackets of the work rolls and the metal strip being acted upon.
- the temperature on the surface of the jackets of the work rolls is set so that a temperature is reached at least immediately before the roll gap, which is below the boiling point of the cooling liquid.
- a method and a device are known from EP 0 367 967 B1, in which the concentration of an emulsion of rolling oil is influenced in a targeted manner and the emulsion or dispersion is collected and returned after exiting the roll gap or when it runs out before the roll gap is separated.
- This makes it possible to produce the emulsion or dispersion that is introduced into the roll gap again and again with a certain concentration in good time before it is drawn into the roll gap.
- the focus of this solution is on the current production of the emulsion and the separation of the media involved.
- the invention is therefore based on the object of creating a method and a device of the type mentioned at the outset without the disadvantages mentioned and of achieving them in particular with significantly improved lubrication in the roll gap.
- this object is achieved in that the cooling medium is applied separately from the base oil to the rollers and only the base oil without water as a carrier medium in a very small amount, based on the usual amount, directly onto the rolling stock over its entire width .
- the invention is based on the surprising finding, confirmed by numerous tests, that with the direct application only of the lubricating additive or oil, which is used in a sealed manner or separately from the cooling medium, the lubricating additive develops its full effect in the roll gap.
- a proposal of the invention provides that the base oil on the inlet side on the top and / or on the bottom of the preferably cold-rolled Rolled good is applied.
- the top and bottom application can be appropriate depending on the material properties of the rolling stock.
- cooling medium is advantageously applied to the rollers both on the inlet side and on the outlet side, in addition to the belt cooling, washing of the work rollers can also be achieved at the same time before the rollers have completed their rotation to the inlet side. As it turned out, not only is the service life of the work rolls significantly increased, but in addition to almost sparkling bright rolls, the rolling stock surfaces are also significantly cleaner.
- a media barrier e.g., between the nozzles / nozzle rows for applying the cooling medium to the rollers and the nozzles / nozzle rows for applying the base oil to the rolling stock.
- a seal in the form of a bulkhead e.g., between the nozzles / nozzle rows for applying the cooling medium to the rollers and the nozzles / nozzle rows for applying the base oil to the rolling stock.
- a base oil nozzle / nozzle row arrangement is directed vertically onto the surface of the rolling stock and another base oil nozzle / nozzle row arrangement is directed obliquely into the roll gap.
- the manufacturing and assembly effort can be limited by preferably arranging the nozzles / nozzle rows in nozzle bars.
- the nozzles / nozzle rows can be adjusted independently of one another or can be acted upon with different pressures.
- coolant nozzles / rows of nozzles arranged on the outlet side can advantageously also be directed onto the rollers.
- a rolling stock 3 is rolled out between an upper work roll 1 and a lower work roll 2 in the direction of passage indicated by the arrow 4; the rolling stock or strip 3 is deformed in the roll gap 15 between the work rolls 1, 2.
- Nozzles / rows of nozzles 7, 7 'and 8, 8' and 9, 9 ', of which the nozzles / rows of nozzles 9, 9' are not shown, are arranged on the inlet side 5 of the roll stand (not shown) for the work rolls 1, 2 Apply the cooling medium supplied to the surface of the work rolls 1, 2.
- an additive or oil is directly from the nozzles / nozzle rows 7, 7 'or 8, 8', vertically through the nozzles / nozzle rows 7 , 7 'on the top and bottom 10, 11 of the rolling stock or applied through the nozzles / nozzle rows 8, 8' with an oblique orientation in the roll gap 15 on the rolling stock 3.
- the amount of additive or oil applied directly by the nozzles / nozzle rows 7, 7 'or 8, 8' is very small and can be supplied, for example, from a container. If the roll stand of the work rolls 1, 2 is operating in reversing operation, corresponding nozzles / rows of nozzles 7, 7 ', 8, 8' or 9, 9 'can also be provided on the outlet side 6.
- the nozzles / nozzle rows 7, 7 ', 8, 8' and 9, 9 'arranged in the exemplary embodiment in nozzle bars 14, 14' can be acted upon separately and set up independently of one another, and can be acted upon with different pressures.
- those for applying the additive or oil to the top 10 and / or bottom 11 of the rolling stock 3 can be vertically directed nozzles / nozzle rows 7, 7 'with a pressure of 2 to 5 bar, the additive / oil nozzles / nozzle rows 8, 8' directed obliquely onto the roll gap 15 with a pressure of 2 to 7 bar and the large amount of the cooling medium on the work rolls 1, 2 applying nozzles / nozzle rows 9, .9 'are supplied with a pressure of 2 to 10 bar.
- the large amount of cooling medium is kept separate from the small amount of additive / oil by the seal formed in the exemplary embodiment as a bulkhead 12, 12 ', which thus fully unfolds in the roll gap 15.
- the seal formed in the exemplary embodiment as a bulkhead 12, 12 ', which thus fully unfolds in the roll gap 15.
- the cleaning of the work rolls 1, 2, 6 nozzles / nozzle rows 13, 13 ' are also arranged on the outlet side, which are directed towards the work rolls 1, 2.
