Continuous heat treatment furnace for aluminum alloy

Abstract

The invention discloses a continuous heat treatment furnace for an aluminum alloy and belongs to the field of heat treatment furnaces. According to key points of the technical scheme, the continuous heat treatment furnace comprises a heat treatment furnace device, a feeding inlet, a discharging outlet and a rotating cylinder. An aluminum alloy transmission device is fixedly installed inside the heat treatment furnace device, the feeding inlet is fixedly formed in one side of the aluminum alloy transmission device, and the discharging outlet is fixedly formed in the other side of the aluminum alloy transmission device. According to the continuous heat treatment furnace for the aluminum alloy, by adopting combination of the rotating cylinder, rotating sand streaks, rotating chains and rotating gears, the aluminum alloy is effectively driven to be rotationally heated, so that the uniformity of heat treatment of the aluminum alloy is ensured, the phenomenon of nonuniform heat treatment ofthe aluminum alloy is avoided, and the working efficiency of heat treatment of the aluminum alloy is improved; by adopting flat burners of rectangular-array-shaped structures, the aluminum alloy is effectively subjected to uniform heat treatment; and by adopting a sealing door, the heat treatment furnace device is effectively sealed when conducting heat treatment, and the internal temperature of the heat treatment furnace device is increased.

[0003] The Chinese patent with the authorized notification number CN104561476A discloses a continuous high-temperature heat treatment furnace, which includes: a furnace body, a carbon tube heating element is arranged in the center of the furnace body; an inlet section and an outlet section are respectively arranged on opposite sides of the furnace body and connected to The carbon tube heating element is axially connected; the inlet of the inlet section is an open end, and a burner is arranged on the periphery of the opening end; the outlet of the outlet section is provided with a sealing cover, and a protective gas inlet is also arranged on the outlet section; and the propulsion system , including a motor and a precision lead screw driven by the motor, the propulsion system is used to push the material from the inlet section through the carbon tube heating element to the outlet section. This continuous high-temperature heat treatment furnace can not only realize continuous heat treatment of materials, but also effectively Prevent the oxygen in the outside air from entering the furnace to oxidize the materials and heating elements. Compared with the batch heat treatment furnace, it can greatly save energy consumption and improve production efficiency. However, when the existing continuous heat treatment furnace heat treats aluminum alloy, it is easy to cause The phenomenon of uneven heat treatment increases the heat treatment time of aluminum alloy and reduces the working efficiency of heat treatment furnace
