He new generation of self-sinking refining flux, with its environmental friendliness, high efficiency and ease of use, is widely favored by users. Especially when used in the pouring ladles of the wheel hub industry, its advantages are further demonstrated. In the production of wheel hubs, gas and flux refining are combined in the smelting furnace fordegassing refining, which improves the purity of the molten aluminum and achieves better results (gas degassing and flux removal of oxide inclusions). In the pouring ladle, The molten aluminum transferred from the smelting furnace, along with the remaining molten aluminum from the original pouring ladle, will generate large amount of oxides suspended in the molten aluminum under the impact of the molten aluminum.
