[0002] The refining agent is a white powder or granular flux prepared by mixing and preparing a plurality of inorganic salts after drying treatment in a certain proportion, and is mainly used for removing hydrogen and floating oxide inclusions in the aluminum liquid. Some components in the refining agent are easily decomposed at high temperature, and the generated gas is easy to react with hydrogen. In addition, the inclusions have strong adsorption force and quickly escape from the melt. Other components have the effect of slag remover.

[0003] The patent with the authorization announcement number CN216367601U discloses an aluminum alloy die casting refining agent spraying device, which comprises a cover plate and a movable shaft. The movable shaft is arranged below the cover plate. The lower end of the movable shaft is fixedly sleeved with a gear. The movable shaft is coaxially and integrally connected with a centrifugal disc above the gear. A throwing guide strip is fixedly installed on the upper side of the body of the centrifugal disc around the shaft. When the patent is used, the powder-like refining agent is loaded into the hopper. When the shaft is stirred, the centrifugal disc and the throwing guide strip throw the refining agent into the refining furnace. However, during the aluminum alloy refining process, the refining furnace is divided into solid and liquid layers. The impurities in the aluminum alloy solution precipitate and float above the aluminum alloy solution. Therefore, after the refining agent is thrown into the smelting furnace, the impurities hold the refining agent and float above the aluminum alloy solution, which prevents the refining agent from contacting and reacting with the aluminum alloy solution, thereby easily causing the refining agent to have an undesirable effect on the removal of impurities in the aluminum alloy solution.
