Heat treatment device for ultra-long aluminum alloy extruded profile

Abstract

The invention relates to the technical field of heat treatment of aluminum alloy extruded profiles, in particular to a heat treatment device for an ultra-long aluminum alloy extruded profile. The heattreatment device comprises a heat treatment device body, the heat treatment device body is composed of a heating furnace, a heat preservation box, a water cooling box and an ultra-long profile, the heating furnace, the heat preservation box and the water cooling box are linearly distributed from left to right, a heating host is arranged at the upper end of the inner cavity of the heating furnace.The heat treatment device has the beneficial effects that through matching of the heating furnace, the heat preservation box, an air cooing section and the water cooling box which are linearly distributed, thus the interrupted heat dissipation of the ultra-long profile is achieved, the temperature difference change of adjacent positions is greatly lowered, and the profile defects caused by temperature difference stress are reduced; and a first limiting block and a second limiting block which are symmetrically distributed front and back are arranged, thus the position of the profile is limited, a motor-driven rotating roller is utilized to drive the profile to rotate slowly, so that the profile is evenly heated and dissipated, and the quality of heat treatment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of heat treatment of aluminum alloy extruded profiles, in particular to heat treatment equipment for super-long aluminum alloy extruded profiles. Background technique [0002] Aluminum alloy extruded profiles require a heat treatment process when they are processed thick. However, due to the different lengths of the produced aluminum alloy extruded profiles, the heating methods during the heat treatment process are also different. [0003] For super-long aluminum alloy extruded profiles, it is difficult to find a heating furnace with a corresponding length, so segmental heating is required. The existing segmental heating method, due to the large temperature difference between different positions during the heating process, the position with a large temperature difference It is prone to cracks or even breakage, and there are problems of uneven heating and heat dissipation during the heating process, which can...

[0003] For super-long aluminum alloy extruded profiles, it is difficult to find a heating furnace with a corresponding length, so segmental heating is required. The existing segmental heating method, due to the large temperature difference between different positions during the heating process, the position with a large temperature difference It is prone to cracks or even breakage, and there are problems of uneven heating and heat dissipation during the heating process, which will easily lead to a decline in the quality of heat treatment of aluminum alloy profiles

[0004] To this end, a heat treatment equipment for super-long aluminum alloy extruded profiles is provided to solve the problems of large temperature difference and uneven heating during heat treatment of ultra-long aluminum alloy extruded profiles
