Embodiment 1
[0035] This embodiment provides a method for preparing a high-performance aluminum alloy radiator plate. The alloy composition of the aluminum alloy plate is composed of the following components according to mass percentage: Si: 0.06%, Cu: 0.17%, Fe: 0.12%, Ti: 0.015 %, the balance is Al and unavoidable impurities, wherein Fe:Si mass ratio=2. By controlling the iron-silicon ratio of the main impurity component of the melt to not less than 1.9, the internal cracks of the slab are reduced, the processing deformation rate of the finished product is reduced, and the copper content is controlled to improve the mechanical properties of the aluminum alloy sheet.
[0036] The preparation method of aluminum alloy radiator plate, the steps are as follows:
[0037] (1) Smelting and casting: batching according to the designed alloy composition.
[0038] (2) Cleaning of raw materials: Clean and dry the surface of each raw material to ensure that the raw materials are free of moisture and ...
Embodiment 2
[0049] This embodiment provides a method for preparing a high-performance aluminum alloy radiator plate. The alloy composition of the aluminum alloy plate is composed of the following components according to the mass percentage: Si: 0.07%, Cu: 0.12%, Fe: 0.15%, Ti: 0.015 %, the balance is Al and unavoidable impurities, wherein Fe:Si mass ratio=2.14.
[0050] The preparation method of aluminum alloy radiator plate, the steps are as follows:
[0051] (1) Smelting and casting: batching according to the designed alloy composition.
[0052] (2) Cleaning of raw materials: Clean and dry the surface of each raw material to ensure that the raw materials are free of moisture and debris; when drying, heat at 120°C at a rate of 10°C / min for 2 hours.
[0053] (3) Smelting and casting the aluminum alloy after batching, including:
[0054] When smelting, first raise the speed of 8°C / min to 740°C to make it completely melted, then put in the preheated aluminum-copper alloy, and then lower i...
