ALUMINIUM ALLOY FORHEAT-EXCHANGER FIN AND METHOD MANUFACTURING THE FIN HAVING ADVANCED STRENGTH AND FORMING

摘要

The present invention relates to a method for manufacturing a heat exchanger fin material used in an air conditioner (air conditioner, etc.) for cooling and heating.;The present invention is Si: 0.11 to 0.15wt.%, Fe: 0.1 to 1.0wt.%, Mn: 0.15 to 0.40wt.%, Ti: 0.01 to 0.10wt.%, Unavoidable impurities: 0.10wt.% Or less Preparing an aluminum alloy composed of balance aluminum, preparing a slab from the aluminum alloy, and heat-treating the slab at a temperature of 500 to 600 ° C. for 1 to 20 hours, and then at a temperature of 400 to 500 ° C. A homogenization treatment step of maintaining the temperature for 30 hours, hot rolling the homogenized slab into a plate shape, and cold rolling the hot rolled plate to a rolling reduction ratio of 80% or more to produce a thin plate, and The thin plate is characterized by consisting of a step of temper treatment at a temperature of 200 ~ 3000 ℃.;According to the present invention, when manufacturing the heat exchanger fin for air purification, the temperature range that satisfies the properties of H26 qualities is widened to improve the workability by improving the workability and improving the quality and the productivity of the reheating treatment. Energy savings are also provided.
