Problems solved by technology

[0008] Therefore, at present, one heating furnace cannot meet the above-mentioned requirements at the same time, so for production enterprises, it is usually necessary to build multiple heating furnaces for different heating and heat treatment requirements. Therefore, the equipment investment of enterprises is very high

Embodiment Construction

[0025] The multifunctional heating furnace of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] As shown in FIG. 1 , the multifunctional heating furnace includes a furnace body 1 , a quenching transfer mechanism 2 and a quenching pool 3 .

[0027] As shown in FIGS. 1 and 2 , the furnace body 1 is composed of a furnace bottom 11 , a furnace roof 12 , left and right side walls 13 , and front and rear walls 14 . The outer layer of the furnace body is made of 4mm ordinary steel plate welded with a large profile steel frame, the inner lining of the furnace body is 2mm 1Cr13 steel plate, and the lining plate of the furnace bottom is 4mm thick 1Cr13 plate to increase the strength of the furnace bottom lining plate. The insulation material aluminum silicate fiber felt + rock wool board is filled between the inner and outer steel plates of the furnace, with a total thickness of 300mm, which is called t...

Abstract

The multifunctional heating furnace includes one furnace body and one quenching bath. The furnace body has a heat insulating lining layer in such a thickness as to ensure the average temperature raise of the furnace wall not higher than 25 deg.c, a blower in the top to form circulating airflow inside the furnace body and to ensure the temperature homogeneity within 3 deg.c, a heater, a conveying chain belt, and a temperature control system. The quenching bath outside the furnace body is provided with one transfer mechanism to transfer blank or workpiece from inside the furnace body to the quenching bath. The multifunctional heating furnace may be used in different types of heat treatment.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a heating furnace capable of performing various heat treatments on aluminum alloys. Background technique [0002] Generally, for aluminum alloy blanks or workpieces, heating or heat treatment, such as quenching, aging treatment, annealing, etc., is sometimes performed according to different uses. Generally speaking, the requirements for heating temperature and furnace temperature uniformity required for the production of aluminum alloy billet heating and forging, annealing and aging heat treatment of forgings and rings are different. The general aluminum alloy heating and heat treatment temperature requirements are as follows: [0003] Aluminum alloy billet heating temperature: 460-530°C, uniform furnace temperature: ≤±10°C. [0004] Quenching temperature of aluminum alloy workpiece: 460~540℃, uniform furnace temperature: ≤±3℃. [0005] Annealing temperature of aluminum alloy workpiece: 310...
