This is because it can break the solid and dense oxide film on the surface of the melt into fine particles, which is beneficial for the hydrogen in the melt to escape from the particle gaps of the oxide film and enter the atmosphere.<\/li>\n<li>Third, the existence of the flux layer can isolate the contact between water vapor in the atmosphere and the aluminum melt, making it difficult for hydrogen to enter the aluminum melt, and at the same time, it can prevent the melt from oxidizing and burning.<\/li>\n<li>Fourth, the flux can absorb the oxides in the aluminum melt, so that the melt can be purified.<\/li>\n<\/ul>\n<p>In short, the role of <a href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/refining-flux\/\">\u062a\u062f\u0641\u0642 \u0627\u0644\u062a\u0643\u0631\u064a\u0631<\/a>\u00a0to remove inclusions is mainly achieved by adsorption, dissolution and chemical interaction with oxide films and non-metallic inclusions in the melt.<\/p>\n<p>In the process of melting aluminum and aluminum alloys, hydrogen and oxide inclusions are the main substances that pollute the aluminum melt. Aluminum can easily form alumina with oxygen. At the same time, it is very easy to absorb gas (H), its content accounts for 70-90% of the total gas in the aluminum melt. The main defects in cast aluminum alloys-pores and slag inclusions are due to the residual gas and Caused by solid particles such as oxides. Therefore, in order to obtain high-quality melt, it is not only necessary to select the correct and reasonable melting process, but also the refining and purification treatment of the melt is also very important.<\/p>\n<p>\u0647\u0646\u0627\u0643 \u0623\u0646\u0648\u0627\u0639 \u0639\u062f\u064a\u062f\u0629 \u0645\u0646 \u0645\u0648\u0627\u062f \u0627\u0644\u062a\u0630\u0648\u064a\u0628 \u0627\u0644\u0645\u0633\u062a\u062e\u062f\u0645\u0629 \u0641\u064a \u0635\u0647\u0631 \u0633\u0628\u0627\u0626\u0643 \u0627\u0644\u0623\u0644\u0648\u0645\u0646\u064a\u0648\u0645\u060c \u0648\u0627\u0644\u062a\u064a \u064a\u0645\u0643\u0646 \u062a\u0642\u0633\u064a\u0645\u0647\u0627 \u0625\u0644\u0649 \u0641\u0626\u062a\u064a\u0646: \u0639\u0627\u0645\u0644 \u0627\u0644\u062a\u063a\u0637\u064a\u0629 (\u0645\u0627\u062f\u0629 \u0627\u0644\u062a\u0630\u0648\u064a\u0628 \u0627\u0644\u062a\u064a \u062a\u0645\u0646\u0639 \u0623\u0643\u0633\u062f\u0629 \u0627\u0644\u0645\u0627\u062f\u0629 \u0627\u0644\u0645\u0646\u0635\u0647\u0631\u0629 \u0648\u0627\u062d\u062a\u0631\u0627\u0642\u0647\u0627 \u0648\u0627\u0645\u062a\u0635\u0627\u0635 \u0627\u0644\u063a\u0627\u0632\u0627\u062a) \u0648\u0639\u0627\u0645\u0644 \u0627\u0644\u062a\u0646\u0642\u064a\u0629 (\u0645\u0627\u062f\u0629 \u0627\u0644\u062a\u0630\u0648\u064a\u0628 \u0627\u0644\u0645\u0633\u062a\u062e\u062f\u0645\u0629 \u0644\u0625\u0632\u0627\u0644\u0629 \u0627\u0644\u063a\u0627\u0632\u0627\u062a \u0648\u0627\u0644\u0634\u0648\u0627\u0626\u0628). \u0648\u062a\u062e\u062a\u0644\u0641 \u0645\u0648\u0627\u062f \u0627\u0644\u062a\u063a\u0637\u064a\u0629 \u0648\u0639\u0648\u0627\u0645\u0644 \u0627\u0644\u062a\u0646\u0642\u064a\u0629 \u0628\u0627\u062e\u062a\u0644\u0627\u0641 \u0633\u0628\u0627\u0626\u0643 \u0627\u0644\u0623\u0644\u0648\u0645\u0646\u064a\u0648\u0645 \u0627\u0644\u0645\u0633\u062a\u062e\u062f\u0645\u0629.<\/p>\n<p><strong>However, any flux used in the aluminum alloy smelting process must meet the following conditions.<\/strong><\/p>\n<ul>\n<li>The melting point should be lower than the melting temperature of the aluminum alloy.<\/li>\n<li>The specific gravity should be less than that of aluminum alloy.<\/li>\n<li>It can absorb and dissolve the inclusions in the melt, and can remove the gas from the melt.<\/li>\n<li>It should not chemically interact with metal and furnace lining.
