The main function of the flux used in the purification of aluminum melt is to remove the slag (? impurity) ?, ? to reduce the hydrogen content, ? to reduce the aluminum loss. ?

In the secondary refining process of aluminum alloy smelting and casting, ? aluminum alloy granular flux is a new, ? fast, ? environmental protection additive. ? Compared with the traditional powdered flux, ? has obvious technical advantages and economic benefits. ? its main functions include: ?

Removal of slag inclusion (? miscellaneous) ? : ? oxides and other solid particles that may be present in the aluminum melt can cause major defects in cast aluminum alloys, ? such as pores and slag inclusion. ? granular aluminum alloy flux can help remove these impurities ? thereby improving the quality of the melt. ?

Reduce hydrogen content: ? aluminum is easy to form oxides with oxygen, ? is also easy to absorb gas, ? hydrogen content accounts for 70% to 90% of the total gas in aluminum melt. The hydrogen content in aluminum melt can be significantly reduced by refining and purifying ? granular aluminum alloy flux ?. ?

Reduce aluminum loss: ? In the smelting process, ? aluminum material is further oxidized in a high temperature environment, ? to produce alumina and hydrogen, ? to increase the content of oxide inclusion and gas. ? The use of flux purification treatment ? can effectively reduce the loss of aluminum liquid and impurity content. ?

In summary, ? the flux used for aluminum melt purification treatment ? significantly improves the purity and quality of aluminum alloy melt through its specific chemical and physical effects, ? thus ensuring the performance and durability of aluminum alloy products.
