Flux Removes Sodium In Liquid Aluminium which has become the focus of melt purification.<\/strong> The gas content and inclusion content in the melt of aluminum and its alloys directly affect the performance of the casting.<\/p>\n

Aluminum Indonesia uses direct-reading spectrometer, XRD, hydrogen measuring instrument, OLYMPUS-BX51 metallographic microscope and electronic universal testing machine to observe and analyze the microstructure, determine the comprehensive mechanical properties of materials and other comprehensive evaluation melt purification effects.<\/p>\n

The research results show that: 1) Through the screening and optimization of molten salt composition, the aluminum alloy composite refining system based on chloride (50wt%NaCl+50wt%KCl), cryolite (Na3AlF6), C2Cl6, and rare earth fluoride (CeF3) has been preliminarily determined Agent.
\nFlux Removes Sodium In Liquid Aluminium which which can make A356 achieve the following purification effects
\nThe residual gas content of aluminum alloy is 0.15vol.%, and the gas (hydrogen) content of the melt is 0.12mL\/100gAl.
\nCompared with the untreated, commercially available common flux, the obtained composite refining agent with the best formula reduces the gas (hydrogen) content by about 3 times and 2 times, and reduces the gas impurity content by about 4 times and 2 times, and the pinhole degree The grade has been reduced by about 4 times and 2 times, the tensile strength of the alloy has been increased by 19.5% and 9% respectively, the elongation \u03b4 has also been improved, and the mechanical properties of the alloy have been improved.

\"Flux<\/p>\n

The process of Flux Removes Sodium In Liquid Aluminium<\/strong>
\nThe cryolite in Flux Aluminium<\/a> can form a transparent colloid with Al2O3, which can dissolve Al2O3.
\nThis reduces the amount of fine Al2O3 remaining in the melt, thereby reducing the Al2O3\/[H] interface, prompting the rapid overflow of H2 bubbles, and also reducing the melt gas content and porosity.
\nThe active rare earth elements replaced in Flux Aluminium, as a surfactant, can improve the trapping effect of cryolite on Al2O3, which is more conducive to the dissolution of Al2O3 by cryolite flux in the refining agent, and it is also beneficial to promote gas overflow.
\nThe trapped and dissolved Al2O3 floats to the surface of the melt with the flux overcoming the viscosity of the aluminum melt, forming slag, covering the surface of the melt, which can isolate the air from the melt, and effectively prevent the melting after purification. The body inhales again.
\nTherefore, there is a phenomenon that the gas decreases with the decrease of impurities.<\/p>\n
