Embodiment Construction

[0014] A method for preparing an aluminum alloy profile for solar photovoltaics, comprising the following steps:

[0015] (1) Put aluminum ingots, magnesium ingots, and scrap aluminum into the smelting furnace for smelting. The melting temperature is 730°C. When it is more than 80% melted, put in Al-Mn, Al-Cr and other intermediate alloys. After they are all melted, Adjust the temperature to 740°C, add 0.3% hexachloroethane and 0.1% sodium fluorosilicate to the melt weight and refine for 15 minutes. After refining, electromagnetically stir for 10 minutes and let stand for 25 minutes. B-La master alloy, heat preservation 6min, slag removal, sampling analysis, strict control of the weight percentage of each element composition of the aluminum alloy solution meets the following requirements: Si0.2-0.5, Fe0.05-0.1, Cu0.1-0.15, Mn0 .1-0.2, Mg0.5-0.8, Cr0.2-0.3, Ti0.05-0.1, Zn0.04-0.08, Nb0.03-0.06, Ta0.024-0.045, Po0.02-0.04, B0.004 -0.008, La0.03-0.05, Eu0.02-0.03, Tb0.01-0.02, t...

Abstract

The invention discloses a preparation method of a solar photovoltaic aluminum alloy profile. The aluminum alloy profile is composed of the following elements, by weight, 0.2-0.5% of Si, 0.05-0.1% of Fe, 0.1-0.15% of Cu, 0.1-0.2% of Mn, 0.5-0.8% of Mg, 0.2-0.3% of Cr, 0.05-0.1% of Ti, 0.04-0.08% of Zn, 0.03-0.06% of Nb, 0.024-0.045% of Ta, 0.02-0.04% of Po, 0.004-0.008% of B, 0.03-0.05% of La, 0.02-0.03% of Eu, 0.01-0.02% of Tb and the balance Al. The aluminum alloy profile provided by the invention has excellent mechanical property, processability and corrosion resistance, and is durable in use.

Description

technical field [0001] The invention relates to a method for preparing an aluminum alloy profile for solar photovoltaic, and belongs to the technical field of aluminum alloy material processing. Background technique [0002] Solar energy is a new type of inexhaustible pollution-free green energy. It is one of the seven emerging industries that my country has determined to focus on. Made of durable 6063 aluminum alloy material by extrusion, it is a new market for the application of 6063 aluminum alloy material and has been promoted and applied globally. However, due to the characteristics of the 6063 aluminum alloy itself and the unreasonable heat treatment process, the mechanical properties of the material are insufficient, the corrosion resistance is low, and the processing performance is poor, which greatly limits the wider application of the material. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing an aluminum...
