The lithium removal agent produced by our company is made of a variety of sodium free salts and inorganic compounds mixed and dried in a certain proportion, which is mainly suitable for lithium removal treatment with high lithium content in liquid aluminum

• Properties: white powder (5kg/ bag)

• Processing temperature: 700℃ ~ 780℃

• Recommended dosage: Add 0.3% ~ 0.5% by weight of aluminum water

When the content of lithium is less than 10PPM, the amount of lithium removal agent is increased as appropriate (if the content of lithium needs to be removed is particularly small, resulting in a small amount of lithium addition, which can not fully reflect the aluminum liquid will cause the effect of lithium removal is not ideal, so the amount is increased as appropriate)

Usage method：

After adjusting the alloy composition, the lithium removal process is carried out, and the scum on the surface of the liquid aluminum is first removed, and the temperature of the liquid aluminum is 700℃ ~ At 780℃, the delithium agent is loaded into the duster, and 99.99% nitrogen is used as the carrier to spray the delithium agent into the aluminum liquid through the duster tube. The duster tube should move evenly in the horizontal direction deep into the bottom of the aluminum liquid, paying special attention to the dead Angle position in the furnace, so that the delithium agent and the aluminum liquid are fully reflected, the process is about 15 minutes, and then fully stirred, standing for about 5 minutes. Then remove the liquid aluminum surface scum, the removal of lithium process is complete. Then sample analysis, such as lithium content exceeded the above process again
