Refine Fluxes

11 8月 Refine Fluxes

Refine Fluxes is a mixture of chloride salts and other inorganic salts (usually after remelting and crystallization dehydration treatment), and there are two kinds of powder and block.
The principle of powdered refining is to use protective gas (chlorine, argon, or their mixture) as a carrier to send the powdered scouring agent below the surface of the aluminum water, and through chemical reaction, inert gas is produced in the aluminum water to adsorb hydrogen bubbles. And high wettability adsorbable material to absorb small particles of impurities.

The purpose of Refine Fluxes is to remove hydrogen and impurities 0.12mm/100gAl
There are mainly the following types of refining agents: one is gas refining agents, which are typically nitrogen, chlorine, argon, or their mixtures.

Its refined principle
With graphite rotors or other facilities that go deep into the aluminum water surface, the large amount of gas diverges into dispersed small bubbles before entering the aluminum water. As a large number of bubbles diffuse and move up in the aluminum water, the hydrogen bubbles and the aluminum water are taken away. Small particles of impurities, so as to achieve the purpose of refining.

Refining Flux, the main component is generally a mixture of chloride, nitrate and other inorganic salts (usually after remelting and crystallization dehydration treatment). There are two types of powder and block. The refining principle is to protect the gas ( Chlorine, argon, or their mixture) as the carrier, the powdered scouring agent is sent below the surface of the aluminum water, and through chemical reaction, inert gas is generated in the aluminum water to adsorb hydrogen bubbles and high-infiltration adsorbables to adsorb small particles Impurities.

The refining effect of molten aluminum has an important influence on the formation of pores, shrinkage holes and inclusions and directly affects the physical and mechanical functions of aluminum alloy castings. There is no high-quality aluminum liquid, even if the subsequent processing and advanced defects occur…

The purification treatment of molten aluminum is one of the measures to ensure high-quality aluminum alloy products and the main method to improve the overall quality of aluminum alloys.
