Granulated Fused Refining Flux is a new type, high-efficiency and eco-friendly flux, it is used in aluminium smelting and casting, the main functions is removing the alkali metals, non-metallic inclusions and reduce the metal lost.
The difference between traditional powder form flux and granulated fused refining flux are that the granulated fused refining fluxes has obvious technical advantage and economic benefits, at the same time, during the reaction with the aluminium melt, the granulated fused refining flux release no-toxic gas and less fume, which greatly improves the production environment.
Based on the above advantages, granulated fused refining flux has attracted more and more attention in the aluminium smelting industry, and there is a tendency to gradually replace traditional powdery fluxes.
The working of granulated fused refining flux:
1.The internal components of Granulated fused fluxes are evenly distributed; depend on the special characteristic of the granules and the difference of the working time of each component, so that the molten flux can fully cover the various sizes of the slags in the molten aluminium during the floating process.
2.The granulated fused refining flux adopt the technology of the surface active adsorption, which can effectively change the surface activity of the flux covered slag mass, so that the flux coated on the furnace of the slag has a strong binding tendency with inert gas, it has a very low affinity with the aluminium melt, thereby improving the slag removal efficiency, achieve better separation of aluminium slag from the aluminium molten.
3.Cover Function: the flux can form a protective file on the aluminium molten to protect the melt react with the air, while maintaining the surface heat of the melt, so that the flux can be separated from aluminium without the addition of exothermic components to heat up, thereby effectively avoiding the exothermic reaction of the melt caused by the exothermic reaction of the melt.
