Embodiment 1

[0036] Embodiment 1: a kind of preparation method of mirror-faced aluminum sheet strip material for automotive interior parts, comprises the following steps:

[0037] (1) Melting and casting, adopting the method of semi-continuous casting, the casting temperature is 690±5°C, the stable production speed of the ingot is 50mm / min, the cooling water temperature is ≤30°C, and the thickness of the obtained ingot is 500~650mm;

[0038] (2) Heat treatment, using the integrated heat treatment of homogenization and heating. First, the obtained aluminum alloy ingot is slowly heated to 630°C at a heating rate of 30°C / h, and then heat-preserved for 16h; then cooled to 500°C and held for 10h. heat treatment;

[0039] (3) Hot rolling, the hot rolling process is divided into the initial stage of hot rolling, the stable stage of hot rolling and the end stage of hot rolling. %; when the thickness of the plate reaches about 280mm, it enters the stable stage of hot rolling. At this time, it is n...

Embodiment 2

[0049] Example 2: (1) Melting and casting, using the method of semi-continuous casting, the casting temperature is 690±5°C, the stable production speed of the ingot is 50mm / min, the cooling water temperature is ≤30°C, and the thickness of the obtained ingot is 500~650mm ;

[0050] (2) Heat treatment, using the integrated heat treatment of homogenization and heating. First, the obtained aluminum alloy ingot is slowly heated to 610°C at a heating rate of 30°C / h, and then heat-preserved for 10h; then cooled to 510°C and held for 4h. heat treatment;

[0051] (3) Hot rolling, the hot rolling process is divided into the initial stage of hot rolling, the stable stage of hot rolling and the end stage of hot rolling. %; when the thickness of the plate reaches about 280mm, it enters the stable stage of hot rolling. At this time, it is necessary to increase the reduction rate to reach 10%~25%; when the thickness of the plate reaches about 50mm, it enters the end stage of hot rolling, an...

Abstract

The invention provides a mirror aluminum plate strip for automobile interior parts and a preparation method of the mirror aluminum plate strip. The aluminum strip preparation method comprises the following steps of melting casting, homogenization and heating integrated heat treatment, hot rolling, cold rolling, mirror rolling and finished product annealing. An aluminum strip metal structure is small in grain size, random in texture distribution and uniform in second phase distribution. The aluminum strip is free of surface shading defects and has a mirror effect, the roughness is lower than orequal to 0.02 microns, the glossiness is higher than or equal to 750 GU, the tensile strength is 100 to 130 MPa, the yield strength is higher than or equal to 70 MPa, and the elongation is higher than or equal to 30%. All performance indexes of the aluminum strip meet the requirements for the use of the automobile interior parts.

Description

technical field [0001] The invention belongs to the field of aluminum alloy materials, and in particular relates to a mirror-faced aluminum strip for automobile interior parts and a preparation method thereof. Background technique [0002] As an Al-Fe alloy, 8000 series aluminum alloy has gradually entered people's field of vision due to its low price, light weight, good heat resistance, and excellent electrical conductivity, and is widely used in packaging, construction, and electromechanical fields. Mirror aluminum refers to an aluminum plate with high reflectivity that makes the surface appear mirror effect through rolling technology. It is widely used in the appearance and structural parts of various high-end civil products, and has a good application prospect. In recent years, the competition in the passenger car market has become increasingly fierce. The beautiful appearance of vehicles has become an important means for various car companies to attract consumers and in...
