Lubricating device for applying a lubricant when rolling a rolling stock

The invention relates to a lubricating device for applying a lubricant during rolling, in particular cold rolling, a rolling stock.

The rolling stock is a metallic rolled strip, which is guided through a nip between two rotating work rolls of a roll stand in order to reduce the thickness of the rolled strip. With the lubricant, the friction between the rolled strip and the work rolls in the roll gap

reduced. For this purpose, the lubricant with the

Lubricating device, for example, applied to a work roll or on a support roller or before the nip on the rolling stock.

Such lubricating devices usually have nozzles for spraying the lubricant. The arrangement of the nozzles depends on several parameters. In particular, it depends on the distance between the nozzles and the surface on which

Lubricant should be applied, from. This distance results in turn from technological requirements of lubricating profile production as well as from space requirements on existing rolling stands. Further, the nozzle arrangement depends on the spray angle of the nozzles to be used, which affects the distance of the nozzles from each other. The complex dependence of the nozzle arrangement of such parameters makes the design of a different rolling stand and

Rolling processes usable or flexible to various rolling stands and rolling processes customizable lubricating device.

There are various devices and methods for

Applying a lubricant during rolling known. EP 1 142 652 A2 and EP 1 142 653 A2 disclose roll cooling and / or lubricating devices for cold strip rolling mills with nozzle bars assigned to the individual rolls and mounted on the roll stands of a roll stand, into which spray nozzles are installed over the width of the rolls. The nozzle bars are by means of a linear actuator formed by actuating cylinder in the direction of its longitudinal axis transversely to the direction of the

Walzbandes slidably and by means of a rotary drive about the longitudinal axis pivotally.

EP 2 465 619 A1 discloses an apparatus and a method for applying a lubricant during rolling of

metallic rolling, wherein a mixture of lubricant and a carrier gas is generated in a sputtering device. The mixture is supplied to an array of spray nozzles and applied by means of a total spray jet to the surface of at least one work roll and / or on the surface of the rolled strip. CH 686 072 A5 discloses a spray system which adjoins an extruder and serves the cooling of metallic profiles on all sides. The cooling media occur

programmatically in the direction of the profiles of spray nozzles. The distance, the cross-sectional distribution and the direction of the spray nozzles are specifically adapted to the geometric shape and the mass distribution of the profiles.

EP 0 153 532 A2 discloses a spray bar in which single-substance membrane nozzles are attached. The cooling medium is conveyed in a longitudinal channel of a first beam part to the respective nozzles, while the channel in the second beam part necessary for the actuation of the nozzle pressurized

Control medium (eg compressed air) contains. Each nozzle has an electromagnetic coil for actuating the membrane, which is actuated via corresponding connections.

The invention is based on the object

Lubricating device for applying a lubricant during Specify rolling a rolling stock, in particular

regarding the adaptability of their production

various rolling mills and rolling processes is improved.

The object is achieved by the features of claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

From the already cited EP 0 153 532 A2 is the

Basic structure of a lubricating device, with a lubricant with the aid of a carrier medium

a beam having a longitudinal extent comprises a first channel for conveying a lubricant and a second channel for conveying a carrier medium, wherein the first and the second channel extend in the longitudinal direction in the interior of the beam. The beam has, across its longitudinal direction, a plurality of nozzles which lubricate the lubricant with the aid of the

deliver pressurized carrier medium. The nozzles are each connected to the first and the second channel, so that through these connections the supply of the individual nozzles with lubricant from the first channel and the

Loading of the nozzles with the carrier medium from the second channel takes place.

A further development according to the invention of such a lubricating device for applying a lubricant when rolling a rolling stock comprises an extruded profile with two profile ends lying opposite one another, between which several lubricant channels open to both profile ends and

at least one open to both profile ends

Carrier medium channel through the extruded profile.

Furthermore, the lubricating device for at least one

Profilende end a connection block, which is connected to the profile end of the extruded profile and

Lubricant connection channels, each with a Lubricant channel of the extruded profile are connected, has. In addition, the lubricating device with the

Extruded profile connected nozzles, each connected to a lubricant channel and at least one carrier medium channel of the extruded profile and for generating and outputting a lubricant-carrier medium mixture of a

Lubricant and a carrier medium are formed. The carrier medium is a gas, for. As air, or a liquid, for. B. Water .

The extruded profile acts simultaneously as a carrier of the nozzles and as a pipe system for the management of

Lubricant and carrier medium to the nozzles. Such an extruded profile can easily from a through

Extruded finished semi-finished product, which already has the carrier medium and lubricant channels are produced. In particular, the length of the extruded profile can be adjusted by simply cutting the semifinished product variable to an extent of a lubrication region to be lubricated. The design effort for the

Production of the lubricating device and its adaptation to parameters of rolling stands and rolling processes is reduced substantially to the positioning of the nozzles, the flexible by introducing (for example, by drilling and / or milling) of Düsenausnehmungen and

Connecting lines between the Düsenausnehmungen and the Trägerermedium- and lubricant channels can be designed. This advantageously reduces the effort and costs for the production of the lubricating device and allows easy adaptation of this production to different

Rolling mills and rolling processes.

The use of an extruded profile with through the

Extruded profile extending carrier medium and

Lubricant channels also avoids advantageous

sealed sealing points along a longitudinal extent of the lubricating device, which, for example, in a modular structure of a lubricating device of individual modules with separate carrier medium and lubricant line sections occur.

The at least one connected to the extruded connection block block with lubricant connection channels advantageously allows a flexible to the length of the

Extruded profiles customizable connection of the

Lubricating device to a lubricant supply system.

An embodiment of the invention provides that at least one connection block has a carrier medium connection channel which is connected to at least one carrier medium channel of the extruded profile. This embodiment of the invention advantageously allows a flexible to the length of the

Extruded profiles customizable connection of the

Lubricating device to a carrier medium supply system.

A further embodiment of the invention provides that the extruded profile of aluminum or copper or a

Aluminum alloy or a copper alloy is made. This embodiment of the invention advantageously significantly reduces the weight of the lubricating device compared to conventional lubricating devices, which are typically made of steel. As a result, the lubricating device can in particular be manually installed and removed and replaced without having to use a special lifting device such as a crane, which the installation and removal and the

Replacement and maintenance of a lubricating device considerably simplified and shortened. Another advantage results from the high corrosion resistance of aluminum, copper and aluminum and copper alloys, especially when using water as a carrier medium. This is important because the water quality in rolling mills generally fluctuates very much or the water is often very dirty.

A further embodiment of the invention provides that each nozzle is connected to a lubricant channel of the at least one branch channel bored from the outside into the extruded profile Extruded profile is connected. Each branch channel of the

Extruded profiles is closed to the outside, for example, with a blind plug. This embodiment of the invention allows a flexible, the respective positions of the nozzles adapted connection of the nozzles with the

Lubricant channels of the extruded profile by drilled from the outside in the extruded stub lines.

A further embodiment of the invention provides that each nozzle by a bayonet closure or by a

Screw connection is detachably connected to the extruded profile. This embodiment of the invention advantageously allows easy installation and removal and replacement of the nozzle, in the case of use of bayonet locks for

Attachment of the nozzles can even be done without tools.

A further embodiment of the invention provides that at least one connection block

Has lubricant bypass segment with lubricant lines, each having a lubricant connection channel of the terminal block with a lubricant channel of the

Connect the extruded profile and redirect the lubricant. Refinements of this embodiment of the invention provide that each Schmierumumleitungssegment a

Sheet stack of several stacked sheets and optionally has a seal arranged on the sheet stack, wherein the sheets and the optional seal have recesses which form the lubricant lines. These embodiments of the invention make it possible to remove the lubricant from the

To redirect lubricant connection channels of a connection block to the lubricant channels of the extruded profile.

This allows the lubricant connection channels

For example, be guided along a rear side of the extruded profile, whereby the lubricating device can be designed to save space. The realization of the deflection of the lubricant by recesses in stacked sheets is advantageous because such sheets cost, accurate and can be made flexible for example by laser cutting.

A further embodiment of the invention provides that each lubricant channel of the extruded profile is connected to a switching valve arranged outside the extruded profile. The switching valves allow a dosing of the lubricant flows to the nozzles. The arrangement of the switching valves outside the extruded profile simplifies the maintenance and, if necessary, the replacement of the

Switching valves and thereby simplifies the maintenance of the lubricating device.

A further embodiment of the invention provides that at each of the two opposite profile ends of the extruded profile, a terminal block with the

Extruded profile is connected, each terminal block having lubricant connection channels, which are each connected to a lubricant channel of the extruded profile. Preferably, both terminal blocks have one

Vehicle media connection channel on with each

Carrier medium channel of the extruded profile is connected.

As a result, the extruded profile is sealed at both profile ends and also a two-sided supply of

Carrier medium and lubricant allows.

A further embodiment of the invention provides a

Nozzle protective frame, which is arranged on the extruded profile around the nozzles and having frame recesses for the nozzles. Due to the nozzle protection frame, the nozzles can advantageously be protected against damage, for example in the case of a strip breakage of the rolled strip or by so-called high-rise cobs (cobbles).

In a method according to the invention for producing a lubricating device according to the invention is the

Extruded profile produced by in one
