Abstract

The invention discloses a non-oxidation vacuum annealing furnace for nonferrous metal. The vacuum annealing furnace comprises a furnace frame (1) and a trolley (14), wherein an insulated fiber module (2) is fixed at the upper part of the furnace frame (1); a track (5) is fixed at the lower part of the furnace frame (1); and wheels (8) and a motor (9) are mounted on a base of the trolley (14). The vacuum annealing furnace is characterized in that a pre-vacuumizing pipe (4) and a protection gas inlet pipe (12) are fixed on a furnace cover (3) and are communicated to an inner container (13); the insulated fiber module (17) of the trolley (14) is against an insulated fiber module (2) of the furnace frame (1) to form a closed hearth (16); and the inner container (13) and an electrical heating element are arranged in the hearth (16). According to the vacuum annealing furnace, high-quality high-aluminum fiber cotton and the 321 stainless steel inner container are adopted, the outlet of a furnace door is sealed and locked, a direct-current fan is mounted in the hearth, and the pre-vacuumizing pipe is added to the furnace cover to ensure non-oxidation and heat treatment quality of workpieces in a treatment process.

Description

technical field [0001] The invention relates to the technical field of heat treatment furnaces, in particular to non-ferrous metal oxidation-free vacuum annealing furnaces. Background technique [0002] For the annealing heat treatment of metal materials, such as the annealing heat treatment of copper, stainless steel, small alloy materials, etc., the existing technology mostly adopts ordinary bell type furnace or well type oxidation annealing furnace, which has poor furnace temperature uniformity and cannot guarantee that the product will be processed during the processing process. in the absence of oxidation. Contents of the invention [0003] In view of the deficiencies in the annealing heat treatment of the above-mentioned metal materials, the purpose of the present invention is to provide a non-ferrous metal oxidation-free vacuum annealing furnace, which constitutes a furnace rack and a trolley structure equipped with thermal insulation fiber modules, and is equipped ...
