Abstract

The invention discloses a manufacturing process for aluminum alloy for doors and windows, which comprises the following main steps: raw material smelting, remelting and refining, hot forging treatment, slag removal, annealing treatment and solid solution. The present invention provides a manufacturing process for aluminum alloy doors and windows. Adding rare earth elements cerium and lanthanum to the steel can reduce the oxygen and sulfur elements in the molten steel so that the impurities in the finished steel are reduced. The oxygen blowing decarburization And high temperature denitrification can improve the machining performance of the alloy. At the same time, put the aluminum alloy raw material into the vacuum induction furnace for calcination, with high heat conversion efficiency, safe and reliable, and avoid impurities in the air from entering the aluminum alloy and affecting the purity of the aluminum alloy. .

Description

technical field [0001] The invention belongs to the field of material manufacturing, and in particular relates to a manufacturing process for aluminum alloys for doors and windows. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. Aluminum alloy is currently the most widely used alloy. [0003] Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industr...
