Embodiment Construction

[0025] Below in conjunction with specific embodiment, further illustrate the present invention. These examples should be understood as only for illustrating the present invention but not for limiting the protection scope of the present invention. After reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent changes and modifications also fall within the scope defined by the claims of the present invention.

[0026] It can be seen from Table 1 that ZL205A alloy requires the content of impurity element iron to be below 0.15%. The alloy uses high-purity aluminum as the raw material, so the impurity element iron brought in by the crucible and smelting tools must be strictly controlled during the smelting process.

[0027] In the following embodiments of the present invention, the control of the alloy to the impurity element iron is achieved by protecting the surface of the cru...

Abstract

The invention relates to a method for preventing the iron increase in a ZL205A alloy melting process. The method comprises the following steps: 1, selecting and preparing a coating: selecting a composite coating of an HGS-1 coating and an aluminum alloy T-1 coating as a coating for a crucible and a melting tool; and 2, coating a protection layer: a, removing an oxidization layer on the surface of the crucible and the melting tool; b, preheating the crucible and the melting tool in a resistor furnace to 120-150DEG C, and starting to coat the protection layer; c, coating with a first layer of the HGS-1 coating with the thickness of 1-2mm, and coating with a second layer the HGS-1 coating of 1-2mm after the first layer is completely dried; and d, coating with a layer of the aluminum alloy T-1 coating with the thickness of 0.5-1.0mm after the second layer is completely dried. According to the invention, control requirements of a harmful element iron by the ZL205A casting aluminum alloy are realized, indexes of the ZL205A casting aluminum alloy can reach GB requirements, and mechanical performances of the ZL205A casting alloy subjected to thermal treatment can satisfy the GB requirements.

Description

technical field [0001] The invention relates to a method for preventing iron increase in the smelting process of cast aluminum alloy, in particular to a method for preventing iron increase in the smelting process of ZL205A alloy. Background technique [0002] ZL205A is an aluminum-copper-manganese high-strength cast aluminum alloy, which has the highest tensile strength among cast aluminum alloy materials. The material has good comprehensive mechanical properties after heat treatment in T5 state. The alloy castings can be used to manufacture parts that bear heavy loads, and have gradually been widely used in important fields such as aerospace, aviation, and nuclear industries. [0003] ZL205A alloy uses high-purity aluminum as raw material, so strict control is required in the smelting process to prevent harmful impurity elements from the charge, crucible and smelting tools. Iron, as the most harmful element in the alloy, should be controlled as much as possible during the s...
