1、 Product Features:

AKJ2 is a composite environmentally friendly granular aluminum and aluminum alloy refining agent, which combines various efficient active salts and auxiliary additives on the basis of conventional refining components, and has stronger hydrogen removal ability and slag aluminum separation effect. High particle strength, low dust content, and uniform distribution during the spraying process. The composite formula can significantly reduce the surface tension of the melt, promote the aggregation and floating of inclusions, especially suitable for the production of aluminum alloys with high cleanliness requirements. The product meets environmental requirements, with low smoke volume and no harmful gas release.

2、 Applicable scenarios

Suitable for refining processes that require high melt cleanliness, such as high-quality recycled aluminum, high-end cast aluminum alloys, aerospace and automotive aluminum alloys. The same applies to aluminum alloys with high magnesium content, and the slag aluminum separation effect is excellent.

3、 Dosage

The recommended addition amount is 0.1% to 0.2% (mass fraction) of the aluminum liquid, with a typical recommended value of 0.18%. For high gas content or high inclusion melts, it can be appropriately increased to 0.25%.

4、 Usage method

After the melt is completely melted and the slag is pre scraped, control the temperature of the aluminum liquid within the range of 720 ℃ to 750 ℃. Using a powder sprayer with dry nitrogen or argon gas as the carrier, spray AKJ2 particle refining agent to the bottom of the melt pool. The jet pipe should move at a constant speed to cover the entire bottom area of the melt pool, ensuring sufficient contact between the refining agent and the melt. Adjust the pressure of the carrier gas and the speed of the powder feeder to evenly add the refining agent and maintain a slight rolling state of the melt, avoiding excessive disturbance. After all refining agents are injected, continue to maintain the carrier gas blowing for 1-2 minutes to promote the upward movement of bubbles and inclusions. Stop blowing air and let it stand for 5-10 minutes to thoroughly remove surface floating debris. For smelting processes with high waste ratios, the above refining process can be repeated once to ensure optimal refining results.
