Oxidation 1090 mirror aluminum mirror machining method

Abstract

The invention discloses an oxidation 1090 mirror aluminum mirror machining method. The oxidation 1090 mirror aluminum mirror machining method comprises steps that mirror raw materials have a tensile strength not lower than 10 MPa and an elongation rate not lower than 6% and have no surface color difference, and the thickness of the mirror raw materials is not lower than 1.5 times of that of finished aluminum products; the viscosity of rolling oil is not higher than 2.0 cst, the convexity of an upper working roller is 2%, and the convexity of a lower working roller is 0%; the total number of mirror rolling passes is not less than 6, a mirror rolling step including rough-rolling the mirror raw materials for 2-4 passes through a working roller with the surface roughness not higher than 0.002 mu m at a single-pass machining rate of 10-13% and then finish-rolling the mirror raw materials through a working roller with the surface roughness lower than 0.002 mu m at a single-pass machining rate not higher than 11%, and lastly, performing edge cutting, tension leveling, cleaning and film laminating to obtain oxidation 1090 mirror aluminum. The oxidation 1090 mirror aluminum mirror machining method is applicable to industrialized mass production, low in production and control difficulty and cost, significant in product market competitiveness and remarkable in economic benefits.

Description

technical field [0001] The invention belongs to the field of mirror aluminum processing, and in particular relates to a mirror processing method of 1090 mirror aluminum for oxidation. Background technique [0002] Mirror aluminum is a special product with surface quality control as the core among processed aluminum products. According to the different processing methods of its finished products, it can be roughly divided into oxidation plates and non-oxidation plates. At the beginning of this century, mirror aluminum for anodic oxidation The preparation process, get rid of the mechanical polishing method and upgrade to the rolling method, and first achieved success in Germany's Anlu and Japan's Sumitomo; my country's domestic mirror aluminum processing began to form a complete industrial chain in 2010, but so far, the products are concentrated in non-oxidized aluminum. For low-end products such as 1100 and 1060 products used in aluminum alloys and 1070 and 1080 used in oxidati...

[0002] Mirror aluminum is a special product with surface quality control as the core among processed aluminum products. According to the different processing methods of its finished products, it can be roughly divided into oxidation plates and non-oxidation plates. At the beginning of this century, mirror aluminum for anodic oxidation The preparation process, get rid of the mechanical polishing method and upgrade to the rolling method, and first achieved success in Germany's Anlu and Japan's Sumitomo; my country's domestic mirror aluminum processing began to form a complete industrial chain in 2010, but so far, the products are concentrated in non-oxidized aluminum. For low-end products such as 1100 and 1060 products used in aluminum alloys and 1070 and 1080 used in oxidation, relevant units in Zhejiang and Henan, which represent the highest level of mirror aluminum processing in China, have made beneficial contributions to the processing of 1070 and 1080 mirror surfaces based on hot rolling. Attempts and breakthroughs, but no breakthrough has been made for the oxidation plate with aluminum purity of 1085 and above, which represents the high-end level of mirror panels
