Embodiment 1

[0060] Attached image 3 Magnesium / aluminum laminates were prepared by the method shown:

[0061] 1) Billet: AZ31 magnesium alloy plate with length and width of 200mm (length) × 50mm (width) × 2mm (height) is selected as double plate 1 and 1060 of 200mm (length) × 50mm (width) × 2mm (height). The aluminum plate is used as the base plate 2, and the surface of the metal plate is polished and cleaned with a steel wire brush with a diameter of 0.3mm. riveting;

[0062] 2) Heating: heating the assembled slab 3 in an argon atmosphere protection environment for 20 minutes, and the heating temperature is 350°C;

[0063] 3) Drum-shaped corrugated roll rolling: the slab 3 is rolled and compounded by using a two-roll mill equipped with an upper roll that is a drum-shaped corrugated roll 5 and a lower roll that is an ordinary flat roll 6. The average diameter of the upper and lower rolls is: D= 150mm, drum height H and roll body length L were 2mm and 150mm respectively, rolling reducti...

Abstract

The invention relates to the field of processing of metal laminated plate belts, in particular to a method for rolling a magnesium-aluminum laminated plate by a drum-shaped corrugated roller. The method comprises the following steps of selecting a magnesium alloy plate with the same length and width as a clad plate and a pure aluminum or aluminum alloy plate as a base plate, cleaning the surface of the metal plate, buckling and assembling the ground surfaces of the base plate and the clad plate together, or buckling and stacking and assembling together. In the first pass, when the drum rolleris used for rolling the magnesium-aluminum laminated plate, a stress peak value can be formed on the lowest metal interface of the laminated plate, and the combination of the middle part of the laminated plate and the wave trough of the wave interface is promoted. In the second pass flattening process, a stress peak value is formed on the edge part of the laminated plate with poor bonding and themetal interface at the wave peak part during the first pass rolling of the plate, large plastic deformation is generated at the same time, and the bonding of the edge part of the laminated plate is promoted. According to the process, rolling is carried out twice in sequence, the bonding of the whole interface is promoted, and the bonding strength of the interface of the laminated plate is improved.

Description

technical field [0001] The invention relates to the processing field of metal laminated strips, in particular to a method for rolling magnesium-aluminum layered laminated plates with drum-shaped corrugated rolls. Background technique [0002] Magnesium alloy has the advantages of low density, high specific strength, high specific stiffness, good thermal and electrical conductivity, and good cutting performance. It is known as "the green engineering material of the 21st century" and is currently the lightest metal structure material that can be used in industrial applications. . However, its disadvantages of poor corrosion resistance greatly limit the wide application of magnesium alloys in various industries. Aluminum alloy, which is also a light metal, has good corrosion resistance and plastic formability, and has good surface repairability and modification. Aluminum is also the most widely used alloy in magnesium alloys to improve strength and corrosion resistance. eleme...
