Abstract

The invention discloses a ZL205A alloy smelting process. The ZL205A alloy smelting process comprises the following steps of S1, carrying out grading refining and rotary blowing, firstly, carrying out rotary blowing by using C2Cl6 and TiO2, and then, carrying out rotary blowing by using pure C2Cl6 and argon; S2, carrying out grain refinement, firstly, adding an Al-4Ti intermediate alloy, and adding an Al-5Ti-B intermediate alloy after refining and degassing are completed; and S3, carrying out vacuum degassing and ceramic net filtering, specifically, after refining degassing and grain refinement of the alloy melt are completed, carrying out filtering through vacuum degassing and a ceramic net. According to the ZL205A alloy smelting process, graded refining and rotary blowing are adopted, the gas content in the alloy melt is strictly controlled through graded refining and argon rotary blowing, and a high-purity ZL205A alloy melt is prepared; and the main body content of a Ti element is controlled by adding the Al-4Ti intermediate alloy, and after refining and degassing are completed, the Al-5Ti-B intermediate alloy is added to complete the overall grain refinement of the alloy melt.

Description

Technical field [0001] The present invention relates to the technical field of metal smelting, and more particularly to a process of ZL205A alloy melting. Background technique [0002] ZL205A is aluminum-copper-manganese-based high-strength cast aluminum alloy, and is the highest tensile strength in the cast aluminum alloy material. The material has good comprehensive mechanical properties after the material is thermally treated T5. The alloy castings can be used to manufacture parts with large loads, and have gradually widely used in important areas such as aerospace, aviation, nuclear industry. [0003] The existing ZL205A alloy smelting method not only does not get high purity alloy, and the obtained alloy quality is relatively low, and it is impossible to meet the needs of actual production. Therefore, it is urgent to develop a ZL205A alloy melting process to solve the prior art. problem. Inventive content [0004] It is an object of the present invention to provide a proces...
