Abstract

The invention belongs to the technical field of aluminum alloy manufacturing, and relates to a heat treatment processing technology for a6082 aluminum alloy medium-thickness plate. An original technology sequence of an aluminum alloy ingot subjected to soaking-sawing and surface milling-hot rolling-solid solution and quenching-stretching-aging is adjusted as the ingot subjected to sawing and surface milling-soaking and hot rolling-solid solution and quenching-stretching-aging, through changing the technology sequence, the consumption of saw blade in the sawing and surface milling process is reduced, the production efficiency is improved, and the performance is not affected.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy manufacturing, and relates to a heat treatment process for a 6082 aluminum alloy medium and thick plate. Background technique [0002] 6082 aluminum alloy uses magnesium and silicon as the main alloying elements, and the main strengthening phase is the intermetallic compound Mg 2 Si, which can be strengthened by heat treatment, has moderate strength. Because of its good formability and machinability, it is widely used in the field of rail transit. 6082 aluminum alloy ingot for rail transit through - soaking - sawing and milling - hot rolling - solution quenching - stretching - aging. When the alloy is cast and solidified, element segregation occurs between the grains and inside the grains. Through the homogenization treatment, the inhomogeneity of chemical composition and structure inside and outside the grain can be eliminated or reduced, and the thermoforming of the ingot can be improv...
