Definitions
- the present invention relates to a device for heat treatment, a use of a device and a method for heat treatment.
- DE 10 2014 108 471 discloses a method for quenching workpieces, in which a fluid cooling medium in the form of individual drops is introduced into a gaseous cooling medium. The workpiece is acted upon by the combined cooling medium, in such a way that the droplets of the fluid cooling medium are transported by means of the gaseous cooling medium to the workpiece in order to arrive at the workpiece to the plant.
- This object is achieved by a device according to claim 1, by a use according to claim 8 and by a method according to claim 9. Further advantages and features will become apparent from the dependent claims and the description and the accompanying figures.
- a device for heat treatment in particular for quenching metals or materials with a fluid idstrom, comprises means for generating or transporting a fluid stream and a conditioning device, wherein the conditioning device is formed at least in two stages and designed such that the temperature the fluid flow is lowered in at least two stages.
- the temperature of the fluid flow is thus sequentially, in particular in at least two steps, adjustable / changeable, in particular reducible.
- the metal or workpiece is a metal or workpiece made of aluminum or an aluminum alloy, wherein the workpiece or the material / metal is quenched, for example, after a heat treatment at about 500 ° C and subsequently aged at about 200 ° C. becomes. In particular, it is for example a T6 or T7 heat treatment.
- the device can also be used with other materials or materials, such as steel.
- Decisive here is the two-stage temperature change, in particular the two-stage temperature reduction, which allows to provide extremely high Abkühlgradienten.
- the fluid flow is meant in particular a coolant flow which is gaseous.
- the conditioning device does not change the state of aggregation of the fluid flow. Conveniently, it is thus ensured that when the fluid stream impinges on the materials / workpieces to be cooled, there is a gaseous fluid flow. This can be prevented with advantage that, for example, in any undercuts of the workpieces to water retention or Wasserstromrungen.
- the device for generating or transporting the fluid flow may be a fan, for example a fan or a fan a fan. It is also possible to use compressors, such as reciprocating compressors, flow compressors and / or turbocompressors.
- the device may also be designed such that it comprises one or more of the aforementioned devices for generating or transporting the fluid flow.
- the conditioning device is designed to increase a heat capacity of the fluid flow.
- it is not just about the temperature or the temperature level of the fluid flow, but also about its heat capacity, which can be increased with advantage by the conditioning or by the process control.
- a first stage is based on heat transfer between the fluid stream and a coolant, while a second stage is based on a change in the state of matter of a coolant which removes heat from the fluid stream.
- the first stage is formed by a heat exchanger and the second stage by a Zumischeinrich- device, wherein the admixing device is designed to mix the fluid flow, mix a liquid medium, in particular to inject or inject.
- a first temperature reduction takes place by a heat exchanger and a second temperature reduction by a fluid injection.
- the admixing device comprises, for example, a suitable injection system comprising one or more injection or injection nozzles or generally a mixing unit.
- droplets in a range of about 5 to 100 ⁇ , preferably in a range of about 10 to 80 ⁇ , injected.
- the admixing unit comprises one or more valves for controlling or regulating the admixture of the medium. It is also possible to use an ultrasonic atomizer.
- the way in which the medium is introduced is not critical here. It is crucial that it is introduced in the liquid state, since the enthalpy of vaporization is to be used in order to obtain the Cool fluid flow. In other words, the fluid flow is thus deprived of heat which is needed for the evaporation of the introduced liquid medium, for example in the form of the drops.
- the medium is water and the fluid stream is air or an air stream.
- Typical flow rates of the fluid flow are in a range of about 5 to 60 m / s.
- the heat exchanger may be a DC or a countercurrent heat exchanger.
- the heat exchanger is flowed through by a coolant, which may be liquid and / or gaseous.
- the fluid flow can also consist of nitrogen or argon or comprise at least one of the aforementioned components.
- the heat exchanger in relation to a flow direction of the fluid flow, is arranged in front of the device for generating or transporting the fluid flow. Conveniently, as it were, a "pre-cooling" realized.
- the admixing device is arranged downstream of the device for generating or transporting the fluid flow, with respect to the flow direction of the fluid flow.
- the at least one heat exchanger before the device for generating or transporting the fluid flow for example, the blower, arranged and the admixing device thereafter.
- the great advantage is that by the arrangement of the heat exchanger, a pre-cooling can be achieved.
- Transporting the fluid stream usually requires a temperature increase
- This at first sight "detrimental" temperature increase can now be ideally converted into an advantage in connection with the admixing device, since this temperature increase results in more liquid medium, in particular water, being added to the fluid flow can.
- the temperature of the fluid flow can now be lowered again in one step, namely by the water injection, wherein at the same time, by the addition of water, whose heat capacity is increased.
- significantly higher cooling gradients can be achieved than merely lowering a temperature level of a fluid flow or coolant flow.
- heat exchangers for example two, three or more, which are connected in series, for example, before and / or after the device for generating or transporting the fluid flow.
- the positioning of the heat exchangers or else of the admixing device or, if appropriate, of several mixing devices or at least several admixing units, which make it possible to add water to the fluid flow at different locations or positions, is free.
- the heat exchanger is accordingly arranged, relative to a flow direction of the fluid flow, downstream of the device for generating or transporting the fluid flow.
- a corresponding sensor or detection system is provided in order to detect the physical properties such as pressure, temperature, humidity, etc. of the fluid flow and z. B. to be able to determine exactly how far a temperature level should be lowered in order to inject a certain amount of water, etc.
- the device expediently comprises a control device which is designed to detect at least the moisture content of the fluid flow,
- these data are used to adapt, control and / or regulate the at least two stages of the conditioning device.
- the device makes it possible to increase the achievable quenching gradients.
- it is possible to achieve very defined and controllable quenching gradients, in particular at the same volume flow.
- the same volume flow is particularly important because it ensures that the components or materials or workpieces are always flowed around the same. So it is not easily possible to increase the cooling power by increasing the volume flow, since the flow and thus the heat transfer to the component, etc. change.
- a means can be advantageously provided by the admixing device to be durable, more or less independent It has been shown that mechanical properties can be improved by this method: mechanical strength parameters such as yield strength and tensile strength can be increased with comparable static and dynamic deformation properties.
- the device thus has the advantage that, for example, a basic conditioning takes place via the heat exchanger, while a fine adjustment is carried out via the admixing device, in which case changes with regard to the fluid flow, which is sucked in, for example, from an external environment, can be compensated.
- the system also offers the advantage that the heat capacity of the fluid flow can be increased in an ideal manner, as a result of which significantly higher cooling gradients are possible than hitherto known.
- the invention is further directed to a use of a device according to the invention for quenching materials, components or workpieces.
- metal in particular aluminum or aluminum alloys.
- the invention is directed to a method for heat treatment, in particular for quenching metals, comprising the steps:
- the temperature change is such that the temperature and the heat capacity of the fluid stream are changed.
- a first stage is expediently based on heat transfer between the fluid stream and a coolant, for example using a heat exchanger, and the second stage on a change in the state of aggregation of a medium, which extracts heat directly from the fluid flow.
- a medium such as water
- the method further comprises the steps:
- Figure 1 a schematic view of a device for heat treatment.
- FIG. 1 shows a schematic view of a device for heat treatment, comprising a device 20 for generating or transporting a fluid flow F.
- the reference symbol S is a flow direction outlined. Seen in the flow direction S, in front of the device 20, a heat exchanger 40 is arranged. As seen in the flow direction S after the device 20, a mixing device 60 is arranged, which is designed to introduce a medium M in the fluid flow F. The thus conditioned fluid flow F can then be applied to a workpiece or to a material or a component 80 in order to cool it, in particular quench it.
- two-stage conditioning device which comprises the heat exchanger 40 in a first stage and the admixing device 60 in a second stage.
- the device has the advantage that, for example, a basic conditioning takes place via the heat exchanger, while a fine adjustment is carried out via the admixing device, in which case changes with regard to the fluid flow, which is sucked in, for example, from an external environment, can be compensated.
- the system also offers the advantage that the heat capacity of the fluid flow can be increased in an ideal manner, as a result of which significantly higher cooling gradients are possible than hitherto known.
