Sucking during the melting process

During the melting process of A356 alloy, the content of water vapor, the water content of the water vapor, the water content of the alchemy and the residue in the air, the water absorption of the stove, the middle bag and the tool Compressed water content. In contact with the aluminum alloy liquid, the aluminum fluid can cause the following reaction:
2AL (L)+3H2O (G) Y-AL2O 3+6 [H]
This reaction is fierce, when the moisture content is 10-21? At the same time, the above response is still underway. Even if the aluminum surface is protected by the aerobic membrane, this reaction can be performed. The density of the oxide film is different and the response speed is different. Due to this reaction, the residue and gas content in aluminum liquid increased rapidly. According to calculations, 1 grams of aluminum fluid and 1 gram of water steam can generate -a12032 and 1224cm322 of 1.9 grams of standard state. Why is lithium modified aluminum hydrogen increase fast, not mostrum aluminum liquid hydrogen increase? After the aluminum liquid is added, the oxide film on the surface of the aluminum fluid always becomes loose, accelerated the above response, and the hydrogen increased rapidly. Therefore, many pinholes appeared in the castings. Instead, money can make the surface oxide more dense, so the casting is not easy to produce pinholes.
