Description

Technical Field

[0001] The utility model relates to the technical field of aluminum liquid impurity removal, in particular to an aluminum liquid refining and impurity removal device. Background Art

[0002] Aluminum plays an extremely important role in national economy and national defense construction. Hydrogen is the only gas that can be dissolved in large quantities in molten aluminum. The defects such as pores and looseness caused by the solidification and precipitation of hydrogen in molten aluminum directly affect the quality, organization and performance of aluminum products. There are three main types of impurities that affect the purity of aluminum: dissolved hydrogen, inclusions and some impurity elements. Hydrogen in molten aluminum can cause pores in die-cast aluminum; inclusions and impurity elements have a great influence on the properties of aluminum and its alloys, which can lead to a decrease in melt fluidity, reduce alloy casting performance, and ultimately lead to the formation of cracks and hard spots in aluminum. It can be seen that the removal of hydrogen and impurities in molten aluminum is very important. The current impurity removal device mostly uses manual cleaning of impurities floating on the surface of molten aluminum, which is prone to the problem of incomplete cleaning, thereby affecting the purity of subsequent molten aluminum impurity removal. For this reason, we propose an aluminum liquid refining and impurity removal device. Utility Model Content
