Embodiment 1

[0014] The heat treatment process of the alloy comprises the following steps:

[0015] (1) Annealing treatment: the aluminum alloy composite foil is formed by cold rolling of 4343 alloy casting billet and 3003 alloy casting billet. The 3003 alloy casting billet is the core material, and the 4343 alloy casting billet is the cladding material. The ratio is 11%. Put the aluminum alloy composite foil into the heat treatment furnace, vacuum the heat treatment furnace, fill it with nitrogen, raise the temperature of the heat treatment furnace to 450°C, and keep it warm for 8 hours;

[0016] (2) Quenching treatment: raise the temperature of the heating furnace to 550°C and keep it warm for 3 hours, then quickly quench the aluminum alloy composite foil into a salt bath furnace at 100°C and keep it warm for 2 hours. The time does not exceed 20s;

[0017] (3) Aging treatment: put the quenched aluminum alloy composite foil into a heat treatment furnace, heat the heat treatment furnace t...

Abstract

The invention provides a thermal treatment technology of an alloy. The thermal treatment technology comprises annealing treatment, quenching treatment, aging treatment and secondary thermal treatment. According to the thermal treatment technology, through homogenizing annealing, chemical components, structure and performance of aluminium alloy composite foil are homogenized, plasticity can be improved by 20%, extrusion force is reduced by 20%, extrusion speed is increased by 15%, and surface treatment quality of the material is improved; and through thermal treatment, metal deformation resistance is reduced, mill load is reduced, remaining rolling oil on the surface is eliminated, composite precision of a product can be improved through relatively low metal deformation resistance and relatively small rolling composite deformation degree, and equipment load is reduced.

Description

technical field [0001] The invention relates to the field of alloy heat treatment, in particular to a heat treatment process for alloys. Background technique [0002] In recent years, with the rapid development of the automobile industry, especially the lightweight process of modern automobiles, the heat transfer aluminum alloy composite foil for automobiles in my country has also developed rapidly. Due to the strategic needs of energy saving, emission reduction and sustainable development, the heat Higher technical requirements are put forward for the selection of exchanger materials, anti-corrosion and bonding technology. The heat exchangers of household air conditioners also put forward strict requirements for heat transfer performance, pollution resistance and corrosion resistance, reliability and service life. Aluminum alloy composite foils still cannot meet the requirements. Emerging markets have technical requirements for high performance products. Contents of the inv...
