tested <strong data-start=\"1740\" data-end=\"1775\">granular aluminum refining flux<\/strong> was developed to improve the interaction between the flux and molten aluminum through controlled reaction and stable particle characteristics.<\/p>\n<h3 data-start=\"1920\" data-end=\"1975\">Improved Oxide Capture Through Activation Technology<\/h3>\n<p data-start=\"1977\" data-end=\"2073\">Oxide inclusions in molten aluminum can reduce melt cleanliness and may lead to casting defects.<\/p>\n<p data-start=\"2075\" data-end=\"2269\">The activation technology used in the refining flux helps improve oxide capture ability during refining, allowing oxide inclusions to combine with the flux and separate from the molten aluminum.<\/p>\n<h3 data-start=\"2276\" data-end=\"2321\">Uniform Granules Improve Flux Distribution<\/h3>\n<p data-start=\"2323\" data-end=\"2409\">The particle design of refining flux affects its flowability and reaction consistency.<\/p>\n<p data-start=\"2411\" data-end=\"2562\">With uniform granules and good flow characteristics, the flux can be added more evenly into molten aluminum, supporting a more stable refining process.<\/p>\n<h3 data-start=\"2569\" data-end=\"2626\">Controlled Reaction Reduces Excessive Melt Disturbance<\/h3>\n<p data-start=\"2628\" data-end=\"2756\">An uncontrolled refining reaction may cause excessive agitation of molten aluminum and increase the risk of secondary oxidation.<\/p>\n<p data-start=\"2758\" data-end=\"2944\">The gradient reaction technology helps control the reaction process, allowing the flux to react progressively rather than producing an overly intense reaction immediately after addition.<\/p>\n<h3 data-start=\"2951\" data-end=\"3006\">Sodium-Free Formula Helps Maintain Alloy Composition<\/h3>\n<p data-start=\"3008\" data-end=\"3119\">For aluminum alloys such as 6061, controlling impurity elements is important for maintaining alloy performance.<\/p>\n<p data-start=\"3121\" data-end=\"3252\">The sodium-free formulation avoids additional sodium input during refining and helps prevent unwanted changes in alloy composition.<\/p>\n<p data-start=\"3121\"

data-end=\"3407\">During the refining process, the aluminum dross showed a dry and loose structure.<\/p>\n<p data-start=\"3409\" data-end=\"3424\">After refining:<\/p>\n<ul data-start=\"3426\" data-end=\"3618\">\n<li data-start=\"3426\" data-end=\"3485\">The dross layer was easy to separate from molten aluminum<\/li>\n<li data-start=\"3486\" data-end=\"3517\">Skimming operation was

data-start=\"4012\" data-end=\"4085\">After refining, the hydrogen content of the molten aluminum was measured:<\/p>\n<p data-start=\"4087\" data-end=\"4125\"><strong data-start=\"4087\"
