The sodium-free calcium removal agent produced by our company is made of a variety of salts and inorganic compounds that do not contain sodium and calcium according to a certain proportion, which is mainly suitable for the removal of calcium in aluminum liquid with high calcium content

• Properties: white powder (5kg/ bag)

• Processing temperature: 700℃ ~ 780℃

• Recommended dosage: Add 0.2% ~ 0.3% of the weight of aluminum water, when the calcium content is less than 10PPM, increase the dosage of calcium-removing agent as appropriate

(The less calcium content, the more difficult it is to remove calcium, such as the amount of calcium removal agent added less, can not fully react with aluminum liquid will cause calcium removal effect is not ideal, so increase the amount as appropriate)

Usage method：

After adjusting the alloy composition, calcium is removed, and the scum on the surface of the liquid aluminum is first removed, and the temperature of the liquid aluminum is 700℃ ~ At 780 ° C, the calcium remover is loaded into the duster, with 99.99% nitrogen as the carrier, the calcium remover is sprayed into the aluminum liquid through the duster tube, the duster tube should go deep into the bottom of the aluminum liquid to do horizontal movement evenly, pay special attention to the dead Angle position in the furnace, to make the calcium remover and the aluminum liquid fully react, the process is about 15 minutes, and then fully stirred, standing for about 5 minutes to remove the aluminum liquid surface float Slag, this calcium removal process is complete. Then sample analysis, if the calcium content exceeds the standard repeat the above process
