Aluminum alloy aging furnace

Abstract

The invention provides an aluminum alloy aging furnace. The aluminum alloy aging furnace a heat treatment chamber which is used for containing an aluminum alloy trolley and being communicated with a hot air circulating system of the heat treatment chamber, wherein the hot air circulating system comprises an air extraction pipeline, an air inlet pipeline and a heater and an air blower arranged between the air extraction pipeline and the air inlet pipeline; a first guide device and a second guide device which are positioned at both sides of the an aluminum alloy containing area are arranged in the heat treatment chamber; the upper ends of the first and second guide devices respectively form a first guide port and a second guide port together with an air inlet duct; and arc-shaped guide surfaces are respectively formed on the first and second guide devices. By arranging the air blower and a circulating air duct, hot air blown into the furnace body can be utilized circularly, thereby reducing energy consumption and improving the use rate of the hot air; by arranging the first and second guide devices symmetrically distributed at both sides of the heat treatment chamber, the heat distribution in the furnace body is more uniform, thereby ensuring the aging quality of aluminum profiles.

Description

technical field [0001] The invention relates to the field of alloy manufacturing, in particular to an aluminum alloy aging furnace with high thermal efficiency. Background technique [0002] The application of aluminum continues to grow due to its light weight, high lightness, weather resistance, good formability and renewable properties. This trend is particularly evident in the automotive industry, household appliances and construction industries, where complex Aluminum is in great demand for shape and higher strength. [0003] In the production process of aluminum profiles, the aluminum profiles need to undergo aging heat treatment after extrusion molding to obtain better mechanical properties of the aluminum profiles; the traditional diesel aging furnace has a large heat storage loss and low heat utilization rate; and due to poor temperature control accuracy Good, the poor sealing of the furnace body can easily cause uneven hardness of the aluminum profile, and the acid...
