Heat treatment furnace for heat treatment of aluminum alloy workpiece

Abstract

The invention provides a heat treatment furnace for heat treatment of an aluminum alloy workpiece. The heat treatment furnace for heat treatment of the aluminum alloy workpiece comprises a furnace body, a heat insulation layer and a glue layer. The furnace body is provided with a working cavity, the heat insulation layer is attached to the inner wall face of a shell of the furnace body, and therefore heat dissipation of temperature in the working cavity is reduced. The heat insulation layer is formed by splicing and / or stacking multiple heat insulation components. The glue layer is attached tothe inner surface of the heat insulation layer. Since the glue layer is attached to the inner surface of the heat insulation layer, the multiple heat insulation portions are connected into a whole, heat is prevented from flowing out of the gap between the two heat insulation portions, therefore, the heat insulation effect of the heat insulation layer on the furnace body is improved, heat dissipation in the working cavity is further reduced, secondary heating time can be shortened, production efficiency is improved, the energy consumption of the heat treatment furnace can also be reduced, andthe using cost of heat treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a heat treatment furnace for heat treatment of aluminum alloy workpieces. Background technique [0002] At present, in related technologies, multiple pieces of insulation cotton are covered between the inner shell and the outer shell of the furnace body of the heat treatment furnace to achieve the effect of heat preservation in the heat treatment furnace. The heat in the heat treatment will flow out of the gap, which not only increases the reheating time of the heat treatment furnace, reduces the working efficiency of the heat treatment furnace, but also increases the energy consumption of the heat treatment and increases the use cost of the heat treatment furnace. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies. [0004] For this reason, the present invention...
