Problems solved by technology

However, considering the difference in the precision of the aging furnace and the wall thickness of the product, when artificial aging is actually carried out, a single-stage aging process at low temperature and long time is often used, so that the energy consumption and cost of artificial aging remain high.

Embodiment 1

[0029] In this example, according to the two-stage energy-saving aging process in the present invention, the 6063-T5 profile of the model N1621a is aged, and the mechanical properties after aging are qualified. The details are as follows: P1. The side widths of the strips are quite different, and the spacing between the profiles can meet the requirements of hot air circulation during the aging process without being too large. Before loading into the aging furnace, the measured value of Webster's hardness is in the range of 2HW to 4HW. P2. The distance between the profile and the top of the aging furnace should be about 50cm, and the distance between the material baskets should be about 30cm. P3. During the double-stage energy-saving aging process test, the temperature accuracy of the aging furnace has been measured many times, which meets the process requirements of ±5°C. After loading the profiles into the aging furnace, set the holding temperature at 175°C. Before the agin...

Abstract

The invention discloses a 6063-T5 aluminum profile two-stage energy-saving aging process. The process includes the following steps that P1, the Vickers hardness is supposed to reach above 2HW before a 6063 aluminum profile is put in an aging furnace; P2, the aluminum profile of which the Vickers hardness meets the requirement is put in the aging furnace; P3, the thermal insulation temperature is set to 175 DEG C, and after the furnace temperature reaches the set temperature, heat preservation is conducted for 40 min; P4, the thermal insulation temperature is reset to 195 DEG C, and after the furnace temperature reaches the reset temperature, heat preservation is conducted for 30 min; P5, after 30-min 195-DEG C heat preservation is finished, a power source of the aging furnace is switched off, and the aluminum profile is braised in the furnace for 40 min; and P6, after 40-min braising is finished, a furnace door is opened and the aluminum profile is pulled out of the furnace for air cooling to the room temperature. Compared with a traditional single-stage aging process, the 6063-T5 aluminum profile two-stage energy-saving aging process can reduce the energy consumption by over 30%, shorten the manual aging time by over 20% and improve the tensile strength by over 10% and the yield strength by nearly 20% of the profile at the room temperature.

Description

technical field [0001] The invention relates to the technical field of artificial aging of aluminum profiles, in particular to a two-stage energy-saving aging process for 6063-T5 aluminum profiles. Background technique [0002] In recent years, with the continuous downturn of the domestic construction industry, the market for aluminum alloy extruded profiles for construction has shrunk. In order to improve the market competitiveness of enterprises, it is imperative to reduce costs. At the same time, resource constraints and room temperature effects of globalization also force companies to save energy and reduce consumption through technological innovation. [0003] For architectural aluminum profiles, 6063-T5 is the alloy state used, and its traditional artificial aging process is a single-stage aging process at 165-190°C for 2-6 hours. Different aluminum extrusion enterprises have different artificial aging temperature and holding time in the specific implementation proce...
