Method for preparing aluminum alloy matt plate

Abstract

A method for preparing an aluminum alloy matt plate relates to an aluminum alloy plate preparing method and solves problems, such as a great number of procedures, great raw material loss, low finished product rate, disappointing mechanical property of the product and easy generation of silking and pine lines on the surface, which exist in present aluminum alloy matt plate production. The method for preparing the aluminum alloy matt plate is as follows: first, casting an ingot and homogenizing annealing; second, hot rolling and curling; third, cold rolling and annealing; and then obtaining the aluminum alloy matt plate. The method has the advantages of simple and easily-implemented procedures, low raw material loss, high finished product rate, good mechanical property of the product, and no generation of silking and pine lines on the surface.

Description

technical field

[0001] The invention relates to a method for manufacturing an aluminum alloy plate. Background technique

[0002] As a new type of aluminum alloy material, aluminum alloy matt sheet is more and more used in architectural decoration, packaging, automobile , home appliances and electronics industries, the market demand is growing rapidly. However, the domestic development technology for aluminum alloy matt plates is still immature, and the commonly used electrochemical matte method and matte treatment method after polishing have many process links, large loss of raw materials, and the yield of finished products is only 60%. Defects such as low mechanical properties, surface silk lines, and many pine lines are difficult to meet the needs of use, which restricts the development of related industries to a certain extent.
