Equipment: aluminium alloy Quenching furnace, aluminum alloy aging furnace, continuous roller hearth quenching furnace
Aluminum alloy quenching furnace is mainly used for aluminum wheel hub Aluminum plate Rapid quenching (solution) treatment of aluminum castings and various aluminum alloy standard parts. Main functions of aluminum alloy quenching furnace: large and medium-sized aluminum alloy products spare parts Solution treatment and aging treatment. Aluminum alloy T4 is solution treated, aluminum alloy T5 is directly aged at low temperature, and aluminum alloy T6 is artificially aged after solution treatment,
Solution treatment: it refers to heating the alloy to the high-temperature single-phase zone and maintaining the constant temperature, so that the surplus phase can be fully dissolved in the solid solution and then cooled quickly (water-cooled) to obtain supersaturated solid solution heat treatment technology.
Incomplete artificial aging: adopt lower aging temperature or shorter holding time to obtain excellent comprehensive mechanical properties, that is, obtain higher strength, good plasticity and toughness, but the corrosion resistance may be relatively low. Aluminum alloy quenching furnace, vertical solution furnace
Complete artificial aging: adopt higher aging temperature and longer holding time to obtain higher hardness and tensile strength, but lower elongation.
