Definitions

  • the invention relates to a heat treatment plant for Solution annealing of aluminum alloy components in the Aviation industry according to existing manufacturing regulations, especially of flat or formed boards Components of specified minimum and maximum dimensions, the components being subjected to a heat treatment, quenching, Undergo cleaning and drying processes, where a a conveyor belt and / or transport rollers in Feed area of the components downstream furnace with a conveying the components through the continuous furnace Conveyor belt and / or transport rollers and with a heater for heating the components to solution annealing temperature is equipped, the continuous furnace a liquid Device for quenching containing quenching medium the components is arranged downstream, with the quenching device a cleaning and drying system connects through which the components by means of a conveyor belt are feasible, and wherein the conveyor belts and / or transport rollers are components of a conveyor system for unpaved mounting and for transporting the Components through the entire system.
  • part of aluminum alloys the strength through special heat treatment methods such as B. solution annealing after the forming process can be increased.
  • the Al alloys are used, for example in a salt bath or air circulation oven at approx. Annealed 500 ° C to 520 ° C.
  • For the heat treatment is a manual binding of the parts to frames or storage in baskets necessary.
  • After the annealing process is carried out an immediate quench in water from always below 20 ° C or for thin components in an air stream. Subsequently can cause an artificial aging process with certain alloys by storage in an oil bath or in a electrically heated air circulation oven at approx. 100 ° C to 200 ° C for 1/2 to 24 hours.
  • the metal Salt residues adhering from the salt bath oven are careful to remove as they attack the metal.
  • US-A-4225121 is a plant for the heat treatment of Components described, the components of a heat treatment, Quenching and subjected to a cleaning process become.
  • the system has a conveyor system with several conveyor belts and / or transport rollers, one of the task area of the components downstream furnace with a Heating for heating the components, a quenching device and one downstream of the quenching device Cleaning system.
  • the cleaning system is included Another continuous furnace for heating the components to one temperature below the above heating temperature on, which eliminates existing stresses within the components become.
  • the components are made by all systems using a conveyor belt of the above Conveyor system led.

  • the stove is a one downstream quenching basin containing liquid quenching medium, the heated metal cross member over a inclined plane can be immersed in the quenching medium.
  • the inclined plane can be rotated in the immediate vicinity of the furnace attached to a wall of the quenching basin and also into the horizontal by means of a wire rope and a winch Location can be raised.
  • EP-A-0232241 is a device for thermal Treatment can be seen in the case of a container with a water bath is provided.
  • the water surface in the tank can assume different heights above the bottom of the container.
  • In the container is a step-shaped heels Conveyor belt system led, the exit of the Conveyor belt by a relatively steep increase in the lowest level of the conveyor belt system.
  • With the known device is thus a deterrent heated components possible at different levels.

  • the conveyor system 1 in the transfer area between continuous furnace 10 and quenching device 14 is designed such that the components under one predetermined angle without bubbles into the quenching medium 13 immerse.
  • the conveyor belt 3 of the continuous furnace runs 10 in its end region under a predetermined Angle of about 15 ° from its horizontal position.
  • On downstream conveyor belt representing a sliding device 4 forms a slope with a in the transfer area adjustable angle from 45 ° to 75 ° with respect to the horizontal.
  • the quenching device 14 is connected a cleaning system 19 and a drying system 20, through which the components by means of a conveyor belt 7 led to the removal area, not shown in the drawing become.
  • the cleaning system 19 has a water spray device 21 for water spraying of the components to be cleaned and a catch basin 22 with a downstream glycol separator 23 on.
