specific Embodiment

[0020] Specific embodiment: rolling of 0.05mm thick magnesium or magnesium alloy foil

[0021] The 1 mm cast-rolled plate was heated to 450°C and kept for 5 hours for homogenization heat treatment to soften it, and then warm-rolled on a two-roll mill. The surface of the roll is preheated to about 150°C, warm-rolled in multiple passes, and kept at 350°C for 15 minutes to eliminate deformation and hardening, until the cast-rolled sheet is turned into a 0.3mm thick foil. Cut the foil blank into 500mm×500mm×500mm pieces, clean each piece separately, and evenly coat the kerosene-dissolved polyethylene solution on both sides. The 5 layers of lubricant-coated foil blanks are neatly stacked, and two 5154 aluminum plates with a size slightly larger than the foil blanks and a thickness of 0.5 mm are used as the cladding plates. The side of the aluminum plate is bent, and the gap formed by the two aluminum plates is equivalent to the core stack. After packaging, the small holes with a diam...

Abstract

The invention provides a rolling method of magnesium or magnesium alloy foils. According to the rolling method, firstly, magnesium or magnesium alloy thin plates are rolled into thin plates with the thickness being 0.3mm to be used as foil blanks. The foil blanks are cut into sheets with the same dimension, the sheets are cleanly cleaned, two surfaces of each sheet are coated with polyethylene solution, and a plurality of foil blanks are overlapped and are covered by aluminum plates to obtain overlapped rolling bags. The overlapped rolling bags are subjected to multi-step crossed rolling by a magnesium alloy block type warm rolling and cold rolling method, after the preset thickness is reached, covering edges are cut, and the foils are separated. The thickness of produced magnesium or magnesium alloy foils is very coincident, for example, 0.05mm pure magnesium foils meet the requirement of certain loudspeaker vibrating diaphragms. A block type rolling method of the magnesium or magnesium alloy overlapped rolling bags is characterized in that the production arrangement is flexible, and the method is suitable for producing plate belt materials with lower yield and variable variety specifications. The method has the advantages that the production rate and the qualified rate are higher, the cost is low, the equipment is simple, and the investment is low.

Description

Technical field [0001] The invention relates to a method for producing magnesium or magnesium alloy foil, in particular to a method for producing magnesium or magnesium alloy foil by cumulative rolling. technical background [0002] The density of magnesium alloy is about 1 / 4 of that of steel and 2 / 3 of that of aluminum. It is similar to plastics. It has high specific strength and specific rigidity, good thermal conductivity, good damping and shock absorption, excellent machining performance, stable part size and easy Recycling and other advantages, with excellent value and broad application prospects, it is known as "the most promising green engineering material in the 21st century". Magnesium alloys have now been widely used in industries such as automobiles, aviation, aerospace, metallurgy, chemicals, communications, electronics and sporting goods. Especially since the early 1990s, increasingly pressing energy and environmental issues have greatly stimulated the development o...
