Aluminum alloy band for jalousie and manufacturing method thereof

Abstract

The present invention discloses an aluminum alloy strip steel rolled stock used for a window blind and the production method thereof. The present invention is characterized in that the strip steel rolled stock includes the components and the weight mixing proportions of the material that iron is 0.26-0.34 percent, silicon is 0.05-0.15 percent, copper is 0.005-0.04 percent, manganese is 0.005-0.04 percent, chromium is 0.21-0.28 percent, magnesium is 2.20-2.48 percent, titanium is 0.025-0.045 percent, rare earth metal is 0.10-0.20 percent, and the residual is aluminum; the production method of the aluminum alloy strip used for the window blind comprises smelting, casting, head cutting and surface milling, homogenization annealing, hot rolling, intermediate annealing, cold rolling, intermediate annealing, cold rolling, draw bending and straightening, stabilizing treatment, and vertical cutting and strip separating. Compared with the prior art, the present invention has the remarkable advantages that the surface quality is good, the size accuracy is high, the shape of strip steel rolled stock is smooth, and the tensile strength, the product forming performance, and the arc stability better conform to the demand to the window blind.

Description

technical field [0001] The invention relates to an aluminum alloy strip for blinds, and also provides a manufacturing method of the aluminum alloy strip. Background technique [0002] As a sun protection device commonly used in modern offices and homes, blinds not only effectively prevent the interference and damage caused by the sun's ultraviolet rays to people's daily work and life, but also can beautify the indoor environment with its unique shape. Among them, the commonly used aluminum alloy shutters have the advantages of beautiful appearance, durability, high regeneration rate, and recyclability. As a decorative material, it is more and more popular in office and home decoration. However, with the continuous improvement of people's requirements for interior decoration materials, the existing aluminum alloy strips for shutters have disadvantages such as low dimensional accuracy, poor shape quality, poor formability and arc stability, and the aluminum alloy strips used i...
