Problems solved by technology

[0006] However, although the effect of regressive heat treatment is excellent, it is difficult for conventional heat treatment furnaces to quickly heat up, keep warm, and cool down in a short period of time, which also makes regressive heat treatment still unable to be quickly popularized.

Abstract

The invention discloses a combined aging furnace for aluminum alloy material regression aging heat treatment, which comprises a furnace body, the furnace body is composed of a plurality of medium and low temperature aging furnaces, a high temperature regression treatment furnace and a medium converter which are assembled together, and the medium and low temperature aging furnaces and the high temperature regression treatment furnace are communicated with the medium converter through channels; the plurality of automatic furnace doors are respectively arranged on the corresponding channels; the plurality of heating devices are respectively arranged in the corresponding furnace bodies; the material conveying mechanism is used for realizing circulation of materials to be subjected to aging treatment in different furnace bodies; the forced cooling device is arranged on the intermediate converter; and the control device is connected with the automatic furnace door, the heating device and the material conveying mechanism and is used for realizing automatic transfer and aging treatment of the material. According to the method, the rapid heating and cooling process of the aluminum alloy material in the aging treatment process can be achieved, and the aluminum alloy material regression aging heat treatment process requirements can be completely met; and meanwhile, production of various complex aging processes can be completed.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy heat treatment equipment, in particular to a regressive heat treatment equipment for Al-Zn-Mg 7-series aluminum alloy materials. Background technique [0002] With the rapid increase of aluminum profiles in industrial applications, the requirements for the mechanical properties of materials are also gradually increasing, especially for auto parts and aerospace fields. In order to improve the lightweight of final products, aluminum alloy products with higher strength are often required . Compared with the traditional 6-series aluminum alloy materials, Al-Zn-Mg 7-series aluminum alloys are more popular in these fields because of their higher mechanical properties. [0003] However, due to the large number of strengthening phases inside the 7-series aluminum alloy, it is easy to form continuous corrosion channels on the internal grain boundaries of the finished material, resulting in signific...
