Definitions
- the invention relates to a device for continuous Cooling a heat-treated wire according to the preamble of claim 1 (see, for example, SU-A-797814).
- Heat treatments are common to manufacture wires to give the desired properties.
- a known method for this purpose is inductive annealing, in which the wire to be treated in a short-circuited loop is passed through a toroidal transformer and the secondary winding of the transformer.
- the of the primary winding the voltage induced in the transformer leaves in the shorted Secondary winding to flow a current at the appropriate Selection of the corresponding parameters for heating the Wire leads to the desired annealing temperature.
- Annealing temperatures can be achieved in the free atmosphere will lead to unwanted surface changes, at least the part of the annealing line on which these temperatures are applied covered with protective gas. That's why before winding up a quick cooling required to outside the annealing range To prevent surface changes and also in the Wrapping to avoid shrinkage stresses.
- DD 210 621 From DD 210 621 is an annular nozzle for stripping the cooling water known from rolling, whose housing is an incoming Walzgut to funnel - shaped tapered nozzle head has, in the one centrally adjustable in a main body in the longitudinal axis arranged, the Walzgut enclosing and at the free end is provided conically expiring guide piece. Between Nozzle head and guide piece is a cone-shaped annular space formed, which ends in an annular gap, from which an am rear end of the nozzle supplied Abstreifmedium (pressurized water or air) is blown onto the incoming wire. about an adjusting thread between the guide piece and the nozzle head the size of the. Annular gap can be adjusted, and with a lock nut can fix the desired setting.
- Abstreifmedium pressurized water or air
- a similar annular nozzle is known from DE-OS 24 34 109 A1.
- the cooling water flows out of a conical spray gap around a hollow truncated cone or funnel-shaped cooling nozzle body around in the form of a hollow cone-shaped beam, against the inlet cone of a wire guide nozzle is directed through which guided the emerging from the cooling nozzle body wire becomes.
- the cooling water enters through a side opening in an annulus, which is in the cone-shaped spray gap continues, and flows through a side housing opening again from.
- the invention is therefore the object of a device for effective cooling of heat-treated wires with low To create space immediately before the short-circuit roll can be arranged and thus the loop resistance minimal affected.
- cooling nozzle By integrating a cooling nozzle with a cooling chamber leaves the cooled wire in a small space to the desired Further processing temperature, such as for winding on a Wire roll, cool.
- a particularly effective cooling can be achieve by the countercurrent process, wherein the cooling medium supplied to the wire against its feed direction becomes.
- the wire runs axially through the cooling nozzle, the a concentric with the wire ring opening, from which Cooling medium, for example water, emulsion or cold air, flows counter to the incoming from the cooling chamber in the nozzle wire. From the cooling chamber, the cooling medium can then escape again or aspirated and reused.
- Cooling medium for example water, emulsion or cold air
- the cooling nozzle with one at one end tapered core and a sleeve with a corresponding Inner cone formed, in which the cone of the core protrudes, so that a cone-shaped annular space is formed, the in an annular gap at the inlet opening of the wire ends.
- the opposite end of this annulus is preferably in a distribution annulus for the cooling medium over, in the radially opens an inlet opening for this medium, resulting in a short length leads.
- the annular gap adjustable by For example, the core formed slidably relative to the sleeve becomes. With the help of a screw thread between core and Sleeve can achieve this easily. To fix the desired Setting one can still have a lock nut on the Provide thread.
- the conical sleeve can expediently form so that their part surrounding the cone tip protrudes into another sleeve, with which it is preferably screwed and which forms the cooling chamber. Through these runs the to be cooled Wire, entering from the opposite side of the cone, through, and the cooling medium flows after leaving the Nozzle against the wire. Through one in the cooling chamber opening outlet can leave it again.
- a threaded connection allowed between core and cooling chamber sleeve expediently an adjustment of the axial length of the cooling chamber, and here, too, can serve a lock nut for fixation.
- the device according to the invention consists of a few, relatively easy to manufacture parts that are easy to compact Assembly unit, which is a highly efficient and in wide range adjustable cooling annealed wires allows.
- a cooling medium suitable liquid or gaseous Media used so that also from this point of view from versatile design options with regard to the application given are.
- the invention contains Cooling device, a nozzle, which by two conical Parts, namely by a trained with an inner cone 4 Conical sleeve 6 and one formed with an outer cone 8 Core 10 and an opening 2 is formed. With a dash-dotted line is a wire 12 indicated, which in the drawing from right to left through the opening 2 passes.
- the outer cone 8 of the core 10 is with a something smaller angle than the inner cone 4 of the conical sleeve 6 is formed, so that between these two cones a conical annulus 14 is formed, which is thinner towards the cone tip, so that its cross-sectional area not only due to the diameter reduction, but also as a result of the thinner lateral surface reduced and that of the large diameter side incoming cooling medium towards the cone tip even stronger is accelerated, whereby the nozzle effect is enhanced.
- cooling medium passes through an inlet port 20 into an annular distribution chamber 22nd a, between a cylindrical portion 24 of the core 10 and a cylindrical bore 26 of the conical sleeve 6 is formed becomes. From this distribution chamber 22, the cooling medium enters the wide end of the annular space 14, in which it due to the accelerated cross-sectional reduction is accelerated and with correspondingly higher speed from the narrow end of the Annular space formed annular gap 3 exits and thereby the opposite the flow direction in the passage opening 2 incoming Wire 12 flows around and effectively cools. The cooling medium passes then into a cooling chamber 28, through which the wire 12th passes through, and leaves the cooling chamber through an outlet opening 30, as the arrow 18 illustrates.
- an insulating sleeve 54 are provided, through which the wire is guided, as shown in Figure 3, in which because of the far-reaching match with figure 1 only a few reference numbers entered are.
- the wire 12 enters the cooling chamber 28 through an inlet opening 32 in an end wall 34 of a cooling chamber sleeve 36 is formed.
- a die 56 are used as shown in FIG.
- the outlet opening 30 is through a lateral opening of the Cooling chamber sleeve 36 is formed.
- the cooling chamber sleeve 36 provided with an internal thread 38, in which the conical sleeve 6 with its inner cone 5 containing Stub 40 is screwed.
- One on this too Threaded locknut 42 allows a fixation of both sleeves 6 and 36 set in one by means of the thread 38 mutual position. In this way can be the axial length of the cooling chamber and thus the residence time of Adjust the wire in this.
- Another adjustment parameter is the conical annulus 14, by more or less deep immersion of the outer cone 8 can be adjusted in the inner cone 4. This happens also with the help of a thread, namely an external thread 44, with which the core 10 in an internal thread 46 of the conical sleeve. 6 is screwed. Again, the desired position can be fix with the help of a lock nut 48.
- the radial inlet and Outlet openings 20 and 30 for the cooling medium expediently formed with threads, in which nipple for Hoses or lines can be screwed.
- a coolant can be e.g. Liquids such as water or suitable Use emulsions that are recycled in a cycle can. But you can also with - optionally cooled - Working with compressed air, the mentioned relaxation effect at the nozzle brings additional cooling. Also at the Invention applied countercurrent principle ensures good efficiency in a small space.
