Embodiment Construction

[0037] Below in conjunction with accompanying drawing the present invention is described in further detail, please refer to Figures 1 to 2 .

[0038] The present invention relates to an embodiment, including a circulating fan, a cold air device, a heating device, an exhaust device, a 90° steering deflector, an equalizing air box, an arc-shaped louver frame, an air duct separation frame and an air guide tube;

[0039] The circulation fan is installed on the heat treatment furnace, and the gas outside the furnace is introduced into the furnace;

[0040] The 90° diversion deflector, the air channel partition frame and the pressure equalizing air box are arranged in the furnace cavity of the heat treatment furnace to jointly form an annular air channel;

[0041] The air guide tube communicates with the annular air channel, and guides the gas sent by the circulating fan into the annular air channel;

[0042] The 90° turning guide device is used as a part of the annular air chann...

Abstract

The invention relates to a gas circulation flow-guiding system used for a heat treatment furnace. The gas circulation flow-guiding system comprises a circulation fan, a cold air device, heating devices, an exhaust device, a 90-degree veering flow-guiding device, a pressure-equalizing air distribution box, an arc-shaped shutter frame, an air duct separation framework and air guiding cylinders. Thetemperature uniformity of the furnace is improved, so that the performance consistency of products is better guaranteed; and the gas circulation flow-guiding system has the modular design characteristic, mounting is easy, structural extension is facilitated, and upsizing development of the heat treatment furnace equipment is facilitated.

Description

technical field [0001] The invention belongs to the field of heat treatment furnace gas circulation diversion, and is mainly applied to aging and annealing heat treatment furnaces of metal plates / profiles. . Background technique [0002] The gas circulation diversion system of the present invention can be used for aging and annealing heat treatment of metal plates / profiles, and the processed products can be used in high-end industries such as aviation, aerospace, and automobiles. In order to meet the high standard requirements of product application performance on material hardness, strength, toughness and fatigue resistance, the temperature uniformity of the product during heat treatment plays a vital role. The effective volume of the furnace body increases, resulting in uneven furnace gas circulation, uneven heating of the product, and the stability of the furnace temperature cannot be guaranteed, and the performance of the product after heat treatment cannot reach the in...
