Semi-continuous casting process using direct water cooling casting method. Direct water-cooling method of cooling intensity is large, the cooling speed, the cast structure refinement, supply 6061T6 aluminum Which is good, increase density tissue, thus improving the mechanical properties and heat treatment ingot effect. Control the casting temperature 710-730 ℃, good quality 6061T6 aluminum Which supply, casting speed 50-70mm / min, 6061T6 aluminum manufacturer, cooling water pressure 0.1-0.3MPa. In order to reduce the tendency of hot cracking, 6061T6 aluminum, to improve the chemical composition of the alloy, use of Al-Ti-B wire line addition, addition rate of 1700-2000mm / min. Electrophoretic coating in aluminum processing advantages are significant. Following is a brief introduction to the advantages of electrophoretic coating of aluminum: 1, can freely control the thickness of the aluminum electrophoretic coating film thickness generally domestic and foreign control 7 microns and 12 microns in two sizes. 2, aluminum electrophoretic coating treatment process requirements are very strict, for enhancing industrial aluminum yield very good. 3, quality electrophoretic coating film is very good. Acrylic resin using amino resin becomes solid, ensures high decorative effect coating and high resistance to erosion corruption, and because of the transparent resin has high performance, very effective highlights the aluminum metal texture, Decorative demand can also be obtained in accordance with matt, sand, pearl and other decorative effects.
