Definitions
- Pre-process heating is often required to the metal components then provided with a coating, for example to be able to.
- the heating of the metal components and their coating usually take place in a completed Chamber, often in a vacuum chamber.
- After treating the Metal components must be cooled, which is why offers to open the chamber easily and the metal components thereby exposing to the ambient temperature. This will, however an uncontrolled thermal shock applied to the metal components, which is why it seems advisable to place the components in the chamber with an inert cooling gas, often called quench gas is referred to cool by the chamber with the inert Cooling gas is flooded.
- EP-A-0 119 186 and FR-A-5 766 95 describe a method for cooling highly heated ones targeted metal components in the areas of the metal components according to the size of their mass are acted upon with an inert cooling gas to such an extent that a uniform Cooling of the entire metal component occurs.
- a treatment device for cooling metal components is further out DE-A-1 274 151 and DE-C-3 405 244 are known.
- the invention has for its object a method for Cooling of metal components heated up in a chamber to propose, regardless of the design of the metal components even cooling of the whole Metal component can be reached.
- the invention is based on a method for cooling metal components that have been heated up in a chamber from in the chamber with the highly heated
- An inert cooling gas is introduced into metal components, and Areas of metal components specifically so different according to the size of their mass are heavily charged with the inert cooling gas, that even cooling of the entire metal component entry provides according to the invention that the areas of metal components with relatively large Mass to be provided with enclosures and the enclosures of areas of different sizes for be individually charged with the inert cooling gas.
- metal components are not just that pure metal components but also coated metal components, how to understand ceramic metal components.
- the different levels of exposure to the individual areas of the metal components to be treated with the inert Cooling gas can be carried out in different ways; for example it is possible through a targeted attachment of more or less gas supply nozzles for the inert cooling gas near the individual areas of the metal components a different amount of exposure to the cooling gas to reach.
- the housings can be compared with Realize little effort, especially if you at the same time to hold the metal components in the chamber be used.
- metal components can be very different design and different Cool mass distribution.
- Metal components are advantageously foot and Provide the top plate of the gas turbine blades with housings, because these parts compared to what lies between them Blade of the turbine blade has a relatively large mass exhibit.
- the method according to the invention also offers the advantageous one Possibility of customizing the metal components on the inside to act with the inert cooling gas, whereby a uniform Cooling of the component is also promoted.
- the invention is also based on the object of a treatment device for cooling metal components with a to propose the chamber containing metal components with which constructively and technically proportionate even cooling of the metal components with little effort can be achieved.
- the solution to this problem is in a treatment facility for cooling metal components with the metal components receiving chamber seen with a reservoir for an inert cooling gas, wherein the metal component has at least two areas, in the invention the chamber has at least two housings, the chamber for areas of the Metal component, which is a relative to other areas of the metal component have a large mass, each has a separate housing, every enclosure is provided with an inlet opening, and the inlet openings are individually connected to the reservoir.
- a major advantage of the treatment device according to the invention is that this is relatively simple can be produced because - usually existing facilities with chamber - only additionally with housings for the metal components with connections of their inlet openings are to be provided.
- the treatment device 1 shown has a chamber 2, preferably a vacuum chamber, in which, with additional devices, for the sake of clarity in the FIG. Not shown, a metal component 3 is highly heated, for example, has been heated to 1100 ° C to carry out a coating.
- the housing 4 is an inlet opening 9 with a inert cooling gas filled in the direction of arrow 10 a gas supply control device 11 and a tube 12 in the housing 4 streams.
- a pipe 16 and an inlet opening 17 in the housing 6 this also filled with the intertening cooling gas that is not over shown column on the edge of the further housing 6 - as in the case of 4 - in the interior of the chamber 2 can flow out.
- each enclosure 4 or 6 via a gas supply control device 11 or 15 can be supplied individually with the cooling gas, it is possible to make each enclosure 4 or 6 as strong by itself with inert cooling gas, as is the case with regard to the masses of the areas surrounded by housings 4 and 6 5 or 7 of the metal component 3 to achieve a uniform Cooling is required. If you also take into account caused by the inert gas in chamber 2 Cooling of the area 8 of the metal component 3, then by operating the gas supply control devices accordingly 11 and 15 achieve that the metal component 3 itself cools evenly overall.
