Homogenization annealing: heating to 475~490℃; holding for 12~14h; furnace cooling. 2) Complete annealing: Heating at 350~400℃; depending on the effective thickness of the material, the holding time is 30~120 minutes;
Cool in the furnace to 300℃ at a speed of 30~50℃/h, and then air-cool. 3) Rapid annealing: heating 350~460℃; holding time 30~120min; air cooling. 4)Quenching and aging: Quenching 495～
505℃, water cooling; natural aging at room temperature 96h.
Aluminum plates and rods for ships
Aluminum plates and aluminum rods are increasingly used in the shipping industry, such as small ships, motorboats, large to 10,000-ton giant wheels, civilian to military, high-speed hovercraft, etc.
For deep-water submarines, from fishing boats to ocean mining ships, aluminum alloy materials with excellent performance are used as hulls, superstructures and various facilities, pipes and vessels.
Using aluminum to build ships can not only save resources and energy, protect the environment, and obtain huge social benefits, but also bring considerable economic benefits.
