Definitions
- Cooling device for cooling a metal strip
- the invention relates to a cooling device for cooling a metal strip after forming in a cold rolling mill.
- the cooling device disclosed therein comprises a plurality of nozzles, which are arranged below the metal strip to be cooled and in each case inject a coolant from a common tank at a right angle onto the underside of the metal strip. After rectangular contact with the underside of the coolant at the bottom of the metal strip initially differs radially or is displaced radially on the underside until it falls back some distance from the nozzle again from the bottom of the metal strip into the tank. In the radial displacement, individual particles of the sprayed cooling medium are displaced with a component of movement in the direction of the metal strip, while other particles are displaced with a component counter to the direction of the metal strip.
- the invention has the object, further to form a known cooling device, a known use for the cooling device and a method for operating the known cooling device to the effect that the heat dissipation is much more effective and efficient.
- the solution provides that a flat plate is provided, which is arranged in an operating position parallel to the surface of the metal strip in the outlet of the cold rolling mill; and that the nozzle is arranged in the operating position for injecting the cooling medium at an acute spray angle into a cavity between the O- ber Design of the metal strip and the opposite plate with an injection direction against the running direction of the metal strip.
- the claimed spraying of the entire cooling medium under the acute spray angle ⁇ against the running direction of the metal strip is advantageously achieved that preferably the entire amount of the sprayed cooling medium delivered by the counter-rotating metal strip shear forces and to form a caused by the shear forces turbulent flow field of the cooling medium in contributes to the shallow cavity between the surface of the metal strip and the opposite plate.
- the present invention brings about advantageous legally enough that an equal amount of the cooling medium allows a much greater heat transfer, ie a removal of a larger amount of heat than was possible in the prior art; insofar the subject of the invention is more efficient than comparable prior art.
- the claimed acute-angled impact of the cooling medium on the O- ber Design of the metal strip that the cooling medium is moved immediately after leaving the nozzle with a moving component against the direction of the metal strip.
- the reflection losses occurring here at an acute angle are substantially lower than in the case of a vertical impact, and therefore the expansion of the coolant counter to the running direction on the surface of the metal strip, ie the effective cooling length, is considerably greater than in the prior art.
- the inventively formed turbulent flow field in the cavity counter to the running direction is much longer / deeper than in the prior art, whereby a much better heat transfer is achieved and more heat can be removed from the metal strip.
- the claimed device is much more effective than the device known from the prior art.
- the surfaces of the metal strip are advantageously also completely or at least partially freed from previously applied rolling emulsions.
- the cooling device according to the invention is particularly advantageous to use in the outlet of scaffolding, in which only minimal quantities of lubricant are deposited on the belt in the inlet.
- Lubricators for targeted friction coefficient adjustment can be optimally used by belt cleaning and media separation.
- the cooling device comprises a plurality of nozzles, which are preferably arranged in at least one nozzle bar transversely to the direction of the metal strip.
- This arrangement of a plurality of nozzles advantageously a larger areal extent of the turbulent flow field is also achieved transversely to the strip running direction; its cooling effect is thereby further improved.
- the nozzles are built into the plate.
- the cooling device advantageously comprises a control or regulation device for controlling or regulating the cooling performance of the cooling device by suitably individually varying the pressure and / or the flow speed with which the cooling medium leaves the individual nozzles, the amount of the injected into the cavity Cooling medium or the injection direction.
- a control or regulation device for controlling or regulating the cooling performance of the cooling device by suitably individually varying the pressure and / or the flow speed with which the cooling medium leaves the individual nozzles, the amount of the injected into the cavity Cooling medium or the injection direction.
- the claimed control or regulating device at any time allows an optimal desired temperature control of the metal strip during a rolling process.
- the control is advantageously supported by a process model.
- a three-dimensional adjustment of the spray direction of the cooling medium advantageously not only allows a variable adjustment of the acute spray angle ⁇ in a plane perpendicular to the plane of the metal strip, but also an adjustment of the azimuth angle ⁇ in a plane parallel to the plane of the metal. tallbandes.
- the variable adjustment of the azimuth angle ß is particularly advantageous for the nozzles in the edge region of the metal strip, because then can be achieved by adjusting the nozzle with an injection direction which is slightly inclined towards the center of the metal strip, the less coolant from the region of the metal strip is displaced and flows more or less unused.
- the device may comprise a positioning device for variably positioning the plate in the operating position or a maintenance position outside of the strip run.
- the maintenance position is much more convenient for maintenance purposes, especially when the nozzles are integrated into the plate, than the operating position.
- the maintenance or rest position is preferably approached automatically in the event of a fault or after completion of a rolling process. A disturbance of the rolling program is particularly present when a tape rupture has occurred, the z. B. is signaled by a signal of the falling strip tension. The retraction of the plate from the tape is then required to eliminate tape scrap.
- the nozzles and the plate can be provided both opposite to the top of the metal strip as well as opposite to the underside of the metal strip.
- the plate is slightly wider than the metal strip and has the plate at its edges parallel to the direction of the metal strip protruding edges, which the edges of the metal strip in the operating position - if also encompass a minimum distance.
- These edges on the plates also counteract the problem described above that the cooling medium in the edge region to flow off too fast and would not have a large cooling effect.
- the edges meet the laterally draining water and thus contribute to an improved cooling performance of the cooling device.
- the lateral outflow of the cooling medium is particularly effectively prevented if the edges of a plate facing the upper side of the metal strip and the edges of a plate facing the underside of the metal strip overlap in the edge regions of the metal strip and, in particular, if there is a seal between them Edges is present. Then, a lateral outflow of the cooling medium is advantageously completely prevented and the cooling medium can flow only in the rolling direction or against the rolling direction. The cooling effect is then particularly large.
- the cooling device according to the invention advantageously also causes an expansion of the power spectrum of (cold) rolling mills, in particular when used in cooperation with a reversing stand or as intercooler cooling between two adjacent rolling mills of a rolling train.
- the cooling device according to the invention allows due to the functional principle described above, a very effective cooling, that is, a strong cooling per unit time. This strong cooling prevents the strip between the stitches is too warm and thus advantageously allows an increased rolling speed and / or a higher and / or faster consecutive stitch loss than in the prior art. In this way, the performance of the cold rolling mill is significantly increased.
- Figure 1 shows the outlet of a cold rolling mill with a leaking metal strip and a transfer table arranged thereunder;
- FIG. 2 nozzles installed in the transfer table
- FIG. 3 shows a plate according to the invention with nozzle bars in the form of a
- FIG. 4 shows the cooling cassettes in the operating position
- Figure 5 shows a cross section through the cooling cassettes in the operating position with laterally overlapping edges
- FIG. 1 shows the outlet of a cold rolling stand 300 with a metal strip 200 running to the left.
- a plate 500 in the form of a transfer table is arranged under the metal strip.
- a nozzle beam 110 with a plurality of individual nozzles 112 is arranged.
- FIG. 2 shows the arrangement of the nozzles 112 and of the nozzle bar 110 in the transfer table 500.
- the nozzles in the transfer table are aligned so that they receive a cooling medium 400 at an acute angle of injection ⁇ against the underside of the metal strip opposite it Spray direction L.
- shearing forces act on the particles of the cooling medium involved, these shearing forces in the cooling medium causing the formation of a turbulent flow field.
- the turbulent flow field is formed in a shallow cavity H between the underside of the metal strip 200 and the top of the transfer table 500.
- the gap height S of this flat cavity H on the one hand must not be too small to direct contact of the metal strip 200 with the transfer table 500th to avoid.
- the gap height S may not be too large, because the larger the gap height, the larger the required amount of cooling medium in order to achieve a desired cooling performance.
- the cooling capacity of the cooling device according to the invention can be individually controlled by means of a control or regulating device 120 by each of the individual nozzles 112, the pressure or the flow velocity with which the cooling medium 400 leaves the individual nozzles, the amount of cooling medium and / or the three-dimensional injection direction R of the cooling medium is suitably adjusted or varied.
- the efficiency and efficiency of the cooling device according to the invention can be further improved in that the azimuth angle ⁇ at the nozzles 112-n in the center of the nozzle beam 110 to zero, but at the nozzles in 112-1, 112-N near the edges of the Metal band is set non-zero. Concrete It is advisable to adjust the nozzles near the edges of the metal strip in such a way that the cooling medium is injected slightly towards the middle of the metal strip on its underside.
- the cooling medium ejected from these nozzles is most effectively involved in the formation of the turbulent flow part and only as little as possible of the cooling medium dispensed by these nozzles beyond the edges of the metal strip transversely to the running direction L of the metal strip in the direction of the arrows V shown in Figure 1 without contributing to the cooling, flows.
- the cooling device according to the invention allows a cooling capacity of up to 30,000 VWm 2 K.
- FIG. 3 shows the plates 500 according to the invention, each with a nozzle bar 110; This arrangement is also referred to below as a cooling cassette.
- Figure 3 shows a cooling cassette for the top of the metal strip 200, denoted by the suffix I at the reference numerals, and a cooling cassette for the underside of the metal strip, denoted by the addition Il to the reference numerals.
- Reference numerals 510-1 and 510-11 denote the edges at the edges of the plates.
- FIG. 3 also shows the positioning devices 600-1 and 600-11 assigned to the cooling cassettes, which enable pivoting of the cooling cassettes from the maintenance or rest position shown in FIG. 3 into an operating position shown later in FIG.
- spindles 700 can be seen in FIG.
- FIG. 4 shows the already mentioned operating position of the cooling cassettes 500-I, 500-II, in which the cooling cassettes or the plates are positioned parallel to the underside and / or upper side of the rolled metal strip 200.
- FIG. 5 shows a cross section through the cooling cassettes in the operating position. It can be seen that the lateral edges 510-1, 510-11 of the upper and lower cooling cassettes enclose the metal band 200 at its edges. In this way, a lateral flow of cooling water is difficult, whereby the cooling effect of the cooling device is improved overall. By a seal 520 between the edges of the upper cooling cassette 500-1 and the lower cooling cassette 500-11, the lateral outflow of the cooling medium can even be completely prevented, whereby the cooling effect is maximized. The cooling water can then emerge only in the rolling direction or against the rolling direction from the frame formed by the cooling cassettes.
- Figure 6 shows the upper cooling cassette 500-1 and the lower cooling cassette in the maintenance or rest position similar to Figure 3, but from a different perspective.
