Abstract

The invention relates to the technical field of waste aluminum recycling, and discloses a method for processing and preparing high-strength aluminum alloy doors and windows by using recycled aluminum.The invention uses waste aluminum as a raw material to replace part of pure aluminum, adds other alloy elements, and processes and prepares recycled aluminum ingots to be further extruded, processedand formed into aluminum alloy doors and windows. The prepared recycled aluminum ingots are superior in mechanical properties to the widely used aluminum alloys on the market, which have a tensile strength of more than 320MPa, an elongation of more than 15%, and an elongation of more than 228MPa; and the price cost is reduced. The invention obtains the aluminum alloy doors and windows by adoptinga semi-continuous casting process; the added waste aluminum has a high composition, but the aluminum alloy doors and windows with excellent performance can be produced; and therefore, the renewable utilization rate of waste aluminum is improved, the production cost is reduced, and the problems of irrational aluminum industry structure and backward development of the secondary aluminum industry aresolved.

Description

technical field [0001] The invention belongs to the technical field of waste aluminum recycling, and in particular relates to a method for preparing high-strength aluminum alloy doors and windows by processing recycled aluminum. Background technique [0002] As a renewable resource, waste aluminum is of great significance to the improvement of economic and social benefits. With the development of the economy, the status and role of aluminum and its alloys in the national economy are second only to steel, and their usage and scope are expanding day by day. Primary aluminum can no longer meet the needs of the society. On the one hand, bauxite is increasingly depleted, and on the other hand, aluminum smelting consumes a lot of energy, which aggravates the energy crisis. Therefore, it is particularly important to effectively recycle and utilize various waste materials and use scrapped parts in the aluminum processing industry. On the other hand, a large amount of energy is con...
