[0031] According to another aspect of the present invention, a method for preparing the above-mentioned corrosion-resistant alloy for high-temperature fans is also provided, please refer to figure 1 , figure 1 It is a flowchart of a method for preparing a corrosion-resistant alloy for a high-temperature fan of the present invention, and the method for preparing a corrosion-resistant alloy for a high-temperature fan includes the following steps:
[0032] Step S1: Raw material preparation: Raw materials are accurately proportioned according to the design composition, and each raw material is prepared with brand-new materials. The surface of all raw materials is polished and baked before use; among them, the raw material nickel needs to be baked at 780°C for more than 4 hours, and the raw material chromium needs to be baked for more than 4 hours. Baking at 400°C for more than 2 hours, raw silicon needs to be baked at 700°C for more than 4 hours; the batching process needs to stri...
