Abstract

The present invention belongs to the technology field of solid solution heat treatment, in particular relates to a vertical quenching furnace used for the solid solution heat treatment on the aluminium alloy pipe, the stick, and the proximate matter. The present invention consists of a cylinder furnace body whose two sides are arranged with fan chambers symmetrically. The underside of the furnace body is arranged with a hydraulically powered furnace door, one side of the furnace body is arranged with a hydraulic lifting device, the materiel pothook of the hydraulic lifting device is arranged in the furnace body through the top of the furnace body, and a plurality of pull rod fixing air guide sleeves are arranged on the inner wall of the furnace body. A circulating fan, an inner wall upper top loading, and an electric heater with the suspending slot structure are arranged in a fan chamber, a stream guidance device is arranged between the fan chamber and the hearth. The present invention occupies small area, the workpieces receives heat evenly, the heating time and the quenching transfer time of the workpieces can be reduced, and the workpiece performance can be improved.

Description

Technical field: [0001] The invention belongs to the technical field of solid-melt heat treatment, and in particular relates to a vertical quenching furnace for solid-melt heat treatment of aluminum alloy tubes, rods and profiles. Background technique: [0002] Currently used for solid-melt heat treatment of aluminum alloy, it is heated by electric heating elements on the furnace wall, mostly in a horizontal structure, and its disadvantages are that the aluminum alloy is heated unevenly, and the quenching transfer time is long, which affects the performance of the aluminum alloy, The equipment takes up a lot of space. Invention content: [0003] The object of the present invention is to provide a vertical quenching furnace with uniform furnace temperature and short quenching transfer time. [0004] The technical solution of the present invention is: a vertical quenching furnace, which is characterized in that it is composed of a cylindrical furnace body with fan chambers ...
