The molten salt used in the flux configuration is a non-metallic salt, which is the object of aluminum melt purification and slagging. In order to avoid secondary slagging of the flux itself, the amount of flux must be minimized, which requires improving the efficiency of flux purification, and after the high efficiency flux is completed, all components are easily separated from the aluminum melt.
The amount of refining flux produced by AdTech according to the current domestic flux product standards is usually 2Kg/ton aluminum, which is almost 400% of the consumption of similar foreign products. Excessive flux usage indicates the low efficiency of the flux. The basic means of configuration to improve flux efficiency is still the precise configuration based on phase diagram analysis and calculation, to accurately grasp the slag-gas interaction mechanism in the aluminum melt, and fully consider the effect of flux on the removal of Na, Li, and Ca alkali metals.
High efficiency flux must focus on the target of aluminum melt purification. The target of slagging is mainly the fine dispersed slag in the aluminum melt. The slagging and degassing focuses on slagging. The target for removing alkali metals and alkaline earth metals is concentrated in Na, Li, Ca. Excessively dispersed purification targets will hinder the working efficiency of the flux. The large-sized slag in the aluminum melt has no effect on the air content of the aluminum melt, and it is easy to remove by physical means such as slagging and filtration. It does not need to be used as a flux configuration. Consider the removal object. In addition to Na, Li, Ca, other alkali metals and alkaline earth metals appear in the aluminum melt with a very small probability, and the flux configuration under normal circumstances does not need to be considered.
High efficiency flux purification is conducive to the improvement of production efficiency and the control of production costs, and has always been the focus of the industry. With the increasingly fierce market competition, efficient refining flux will undoubtedly be favored by aluminum processing enterprises.
