The new generation of self-settling refining agent, with its environmental protection, high efficiency, easy to use and other characteristics, is welcomed by the majority of users, especially in the wheel industry on the use of casting ladle, but also reflects its advantages. In the hub production, gas and flux refining are combined in the melting furnace for degassing refining, which improves the purity of the aluminum liquid and achieves a better effect (gas degassing, flux removal oxidation slag inclusion). In the transfer ladle, the aluminum liquid transferred from the melting furnace and the original remaining aluminum liquid in the transfer ladle will produce a large number of the most compounds floating in the aluminum liquid under the impact of the aluminum liquid
• Traditional practice: The slag cleaning agent is injected with aluminum liquid, plus rotary degassing, because the specific gravity of the slag cleaning agent is small, the opportunity to enter the aluminum liquid is very small, and the role of degassing on the oxide in the aluminum liquid is relatively small, so that the upper aluminum liquid quality is good, the middle is slightly worse, and the lower part is poor
• Self-sedimentation refining agent is successfully developed in this case, without changing the existing production process, deep removal of the bottom of the liquid aluminum oxidation slag, the resulting lava flow in the rotation of the stirring more evenly dispersed in the liquid aluminum, in the floating process, gas degassing, the flux to remove the liquid aluminum oxidation slag, in order to obtain better quality of liquid aluminum
• Character: gray-black, blocky
• Processing temperature: 720℃ ~ 760℃
• Recommended dosage: 0.1% ~ 0.3%
Major advantage
1, both gas refining and flux refining combined advantages, good degassing effect
2, small amount of addition, simple and convenient operation, reduce the labor intensity of workers
3, the utilization rate of flux is high, and the degassing and slag removal of melt are effectively realized
Usage method
Throw the bulk refining agent directly into the ladle to finish the reaction
