Definitions
- the invention generally relates to the technical field of rolling a metallic material to be rolled, in particular one in a nip between two work rolls
- a lubricant is used.
- liquid or gaseous treatment media are used in the rolling of metallic rolling stock, for example a metal strip, for the purpose of lubrication and cooling.
- These treatment media vary depending on the type of rolling process: during hot rolling, where the rolling stock is heated to several 100 ° C
- Cold rolling in which the temperature of the rolling stock before the rolling process is usually below 100 ° C, the lubrication in the nip is usually done by a cold rolling oil, in addition, a cooling liquid is used.
- the invention is based on the object to provide a method and apparatus for applying a lubricant when rolling a metallic rolling stock, in which the lubricant consumption is minimized.
- the medium used for roller gap lubrication is not a rolling fluid but a spray, that is to say a mixture of rolling oil and a carrier gas.
- the lubricant is divided in an atomizer into finely distributed liquid drops and by means of the
- Carrier gas entered into the nip can either by spraying on the surface of the work rolls, and / or on the surface of the incoming into the roll gap
- Lubricant as a spray the lubricant consumption can be kept relatively low.
- the droplet-form lubricant wets very selectively only ene
- the decisive factor is merely that a sufficient amount of oil for lubrication reaches the nip; This can basically be done by spraying on the surface of the work rolls or on the surface of the incoming
- the concentration of the lubricant in the nip is significantly higher. This increases the efficiency of the lubricant used, because just as much rolling oil passes into the rolling gap as required depending on the type of rolling stock to reduce friction in the nip is. Seen in the width direction of the rolled strip, the invention enables a uniform application of the lubricant. This reduces the risk that in the nip in the width direction different friction conditions
- the desired final thickness of the metal is comparatively low and it can easily lead to a local breakage of the lubricating film.
- a good surface quality of the metal strip is sought, which requires adequate lubrication in the nip.
- Another advantage is the fact that the lubricant is used in pure form, that is not in the form of an emulsion, so that an emulsifier in the lubricant is not required. This results in the advantage that the oil is relatively easy from
- Coolant e.g. Water
- Coolant e.g. Water
- Circulation can be performed.
- Cross sections can overlap in the edge area. In this way, viewed over the width of the rolled strip, a fan-shaped overall spray can be generated, with which the lubricant homogeneous and targeted in the nip
- spray nozzles which have at least two outlet openings. Depending on the shape of these at least two
- Outlets can be very well a uniform surface concentration of the lubricant during the order
- nozzles that are spherical have curved mouthpiece. On this curved
- Mouthpiece are two with respect to an axis of symmetry
- a spray can be formed with a comparatively small number of nozzles, which applies the lubricant evenly.
- the cross section of these sprays
- the spray is formed from a juxtaposition of individual spray jets, each of these spray jets in its
- Seen width direction is approximately parallel to the axis of the two work rolls.
- a carrier medium for the lubricant droplets can be used in a simple embodiment of the process air.
- Figure 1 is a schematic vertical section through a
- Roll stand the arrangement of the invention Apparatus for introducing a lubricant into the roll gap
- Figure 2 shows a spray bar with lined up
- Figure 3 is a sectional view of a
- Atomizing device including spray nozzle
- Figure 4 shows an embodiment of the mouthpiece of a spray nozzle in a spatial and in a sectional view
- Figure 5 is a detailed view of the rolling gap lubrication in a comparative representation between lubrication with emulsion and lubrication with rolling oil.
- FIG. 1 shows in a highly simplified representation a vertical section through a rolling stand.
- the rolling stand consists essentially of the two work rolls 2 'and 2' ', and the respective support rollers 3' and 3 ''. in the
- Rolling gap 8 is between the two work rolls 2 'and 2' 'a rolled strip 28 in the direction indicated by the arrow from left to right passed.
- the device 1 according to the invention is sketched in each case on the upper side and the underside of the rolled strip 28, which sprays an atomised rolling oil in the direction of the roll gap 8. The atomization of the rolling oil takes place in one
- Atomizing device 4 which is supplied via lines 6 and 7 rolling oil or air. As will be explained in more detail below, in the atomizing device 4 is a mixture of air and
- Spray nozzles 5 is applied as a spray. This spray is deposited on the surface 21 of the work rolls 2 'and 2' 'and / or on the surface 23 of the rolled strip 28, whereby the desired reduction of the
- Friction conditions in the nip 8 is effected.
- rolling oil is collected together with the coolant and recycled by means of a conveying and reprocessing plant.
- Each spray nozzle 5 is in each case via a first line 6 rolling oil and via a second line 7 air
- Each spray nozzle 5 generates a spray jet 9, which is formed flat in cross section 15 seen.
- FIG. 3 shows a sectional drawing of FIG
- Atomizing device 4 As already stated, this atomizing device 4 in each case via a connecting line 6 rolling oil and via another connecting line 7 air
- Apertures can be adjusted in a wide range. These orifices in the inlet of air and oil are in the
- Atomizer 4 interchangeable. That's it possible to produce a suitable mixture of air and liquid particles as required.
- This mixture is fed via a short connector of a spray nozzle 5.
- the spray nozzle 5 is spherically curved in the region of an orifice 18. In the area of the spherical curvature 12, two outlet openings 10 are formed. Each of these
- Outlet openings 10 is formed by a slot in the region of the mouth 18.
- the preparation of this slot in the spherical curvature 10 can be easily done by a cut with a saw blade.
- FIG. 4 shows two views of the mouthpiece 18: in the upper illustration, the mouthpiece 18 is in one
- the mouthpiece 18 is convexly curved outwards.
- the curvature 12 is a circular arc.
- a corresponding curvature is also formed on the inner wall of the mouthpiece 18. At the zenith of curvature 12 are two through cuts
- the planes of the incisions 10 are at an angle 30 to each other.
- the slot width 14 of these cuts is advantageously between about 0.6 to 0.7 mm.
- a spray 9 is formed, which has a flat cross-sectional area and a substantially homogeneous
- Distribution of the lubricant concentration has.
- Figure 5 illustrates in a highly simplified representation of the lubrication in the nip, the upper diagram shows the lubrication with emulsion according to the state of Technique, the lower illustration, the invention
- Cost advantage Another advantage results from the greatly reduced friction in the nip, whereby the rolling forces and rolling moments for the rolling process can be reduced. Especially during cold rolling, a very good surface quality of the rolled strip can be achieved.
