Übersetzung für "Air quenching" in Deutsch

This can take place using air or by quenching with water.

This can take place, for example, using air or by quenching with water.

In particular, this is done directly with the process heat of the forming process and by air quenching.

The new formation of dioxins and furanes is prevented by a subsequent air quenching.

The quenching air A which is fed-in directly after the combustion zone, cools off the hot gases and prevents a further increase of nitrous oxides by freezing-in the NOx -formation reactions.

However, because quenching air is fed-in, such post-reactions are "frozen" before the reaction partners enter the mixing chamber.

This effect can be further enhanced by the provision that the entire mixing air can be fed-in exclusively through the burners with the fuel supply switched off, and in the form of quenching air through the openings of the primary combustion chamber into the mixing chamber.

Then, no further openings for supplying combustion air or mixing air are provided in addition to the openings for the entry of quenching air.

The openings 20 for the entry of the quenching air A are oriented radially and pass through the flame tube shell 21 and the refractory lining 24.

Provided below the common container are two blowing or ventilating boxes 41, which are each supplied with quench air from a quenching chamber 40A, 40B, and two spinning chambers 42, while the groups of filaments 43 are wound into yarn packages 45 on bobbin tubes 44.

In the wall parts 32 of the hollow chamber 30 and in the side walls of the ribs 31 there are openings 33 and 34 for the exit of hot air (during transport) and of cold air (during quenching).

Provided in the course of the waste-gas line is a quench (20) for the abrupt cooling of the waste gas by cold quenching air acting on it.

The waste-gas piping as claimed in claim 2, wherein means are provided for eddying the quenching air.

The nozzles 7, from which pressurized air exits to create the air bearings, are placed obliquely in such a way that they point away from the heating zone 2 to the quenching zone 3, by which it is prevented that cooled air from the quenching zone 3 flows in the direction toward the heating zone 2 .

It is also conceivable to use air as the quenching gas, in particular air that is cooler than the flame 35 .

Thus, it has been found that in conventional air quenching, the tensile strength and yield strength of castings consisting of the alloy processed according to the invention is lower compared to castings which consist of standard alloys.

There are two kinds of tempered glass production processes: One is to process ordinary flat glass or float glass under specific process conditions by quenching or air-cooling quenching.

It includes a combination of primary (afterburner chamber, air quenching) and secondary measures (highly efficient fibrous filter).

The hot gas flow, which is cooled down to the turbine entry temperature, then leaves the mixing chamber 1 through its outlet opening 10 and flows through the transition section 11 to the inner housing of the gas turbine, as indicated by the arrows H. In full-load operation, only the hot gas jets (which already carry the mixed air supplied as the quenching air A with them) are mixed together in the mixing chamber 1.

The casting which is obtained after casting and solidification undergoes a heat treatment in which it is initially solution annealed at 530-545° C. The casting is cooled down in an accelerated manner from the solution annealing temperature using water or in an air stream, wherein quenching with water in particular is considered as advantageous in respect of the desired high strength, but cooling in an air stream is recommended in case the casting tends to form cracks during a relatively fast cooling procedure due to its complex shaping.

The purified quench air is withdrawn from the gas purification system via pumps (18).

In other cases, the article can be cooled in air or quenched with water.

This variant, in the case of leaks or pressure variations, prevents an immediate flowing-out of the contaminated quench air into the surroundings.

The area below the passage is preferably not sealed off from the ambient air, so that the quench air is only partially sucked by the passage, but spinning fumes which could dirty the passage are blown out laterally further upwards.

This outlet orifice must therefore be configured in such a way that, in addition to the high rate of passage of the filaments formed, it also permits a good seal against an exit of the contaminated quench air in the interior of the spinning shaft.

This object is achieved by spinning such polymers into a closed spinning shaft, quenching the filaments formed and by subsequent special purification of the quench air conducted out of the shaft.

It has been shown that the used quench air must be purified by contact with an adsorbent for said troublesome gases and/or vapors.

Alternatively, the aluminum sheet metal blank is after being heated to the heating temperature first cooled down in air or quenched with a medium, and is subsequently cold-formed in a tool.
