17 6月 Alu Refine Agent
Alu Refine Agent is a white powder or granular flux. It is prepared by drying a variety of inorganic salts and mixing them in a certain proportion. It is mainly used to remove hydrogen from the aluminum liquid and float the slag for oxidation.
Due to the low density, high specific strength, good conductivity, beautiful outer tube, and moderate price of the aluminum alloy, the hydrogen atoms in the solution spontaneously form hydrogen during the production process, and hydrogen and inclusions solidify in the aluminum alloy solution.
Bubbles are formed during this process, leading to defects in the aluminum alloy member. Due to the presence of impurities and gases in the aluminum alloy solution, refining treatment is essential.
Alu Refine Agent formula characteristics
Some components in the aluminum alloy refining agent are easily decomposed at high temperature, the generated gas easily reacts with hydrogen, and has strong adsorption force with the slag and quickly escapes from the melt.
Other components have the effect of removing slag. Aluminum alloy refining agent is white powder or granular flux.
After drying with various inorganic salts, it is prepared by mixing in a certain ratio.
It contains organic compounds that effectively decompose N2 and CO2 gases.
The refining agent uses its main component, NaNO3, in which graphite does not undergo chemical reactions, and at high temperatures, its own heat generates gases N2, CO2, NO, etc. that will not melt in the aluminum alloy liquid. Perform refining and purification actions.
Alu Refine Agent detection technology
Aluminum alloy refining agent formula testing process: sample preparation ―professional instrument analysis ―engineering analysis
Aluminum alloy refining agent composition testing formula identification: analysis of the name and content ratio of the raw materials of the aluminum alloy refining agent, as well as in-depth analysis of standard products and effects preparation and development services.
Granulated Flux is prepared by mixing various inorganic salts in a certain proportion after drying treatment. It is mainly used to remove hydrogen and floating oxidized slag inside the aluminum liquid.
Function: The particle refining agent is mainly used to remove the hydrogen in the aluminum liquid and floating oxidized slag, so that the aluminum liquid is more pure, and also has the role of the slag cleaning agent.
Features: Part of the components in the granular refining agent are easily decomposed at high temperature, the generated gas is easy to react with hydrogen, and has strong adsorption force with the slag, and quickly escapes from the melt. Other components also have the function of slag cleaning agent.
Scope of application: Applicable to commonly used aluminum alloys (alloys with high magnesium content and aluminum-magnesium alloys cannot be used), and pure aluminum smelting, degassing refining and slag removal.
Usage: Sprinkle the granular refining agent on the liquid surface, quickly press it into the aluminum liquid, stir it fully and let it stand, slag slag; for example, with the help of a spray machine, use an inert gas to spray the refining agent into the aluminum liquid.
Dosage: The general dosage is about 0.3% of the weight of the aluminum liquid, depending on the purity of the aluminum liquid.
Packaging: Corrugated carton packaging, 20 or 25 kg per carton, 2.5 kg per sachet. Can also be packaged according to user requirements.
Storage: Store it dry. If it gets wet, you can continue to use it after drying.
