Rotary Degasser with Nitrogen<\/strong><\/p>\n

Rotary Degasser is the purpose of spraying Nitrogen into molten aluminum to remove hydrogen.
\nAdem\u00e1s, la desgasificaci\u00f3n tambi\u00e9n se considera un m\u00e9todo muy eficaz para hacer flotar las impurezas.
\nTwo main theoretical modes have been proposed to explain the principle of degassing. The macro mode considers that the removal of each impurity is similar in nature. The microscopic mode, that is, according to this theory, due to the higher vapor pressure of Hidr\u00f3geno de aluminio<\/a>, the dissolved hydrogen diffuses into the gas in the injected aluminum liquid.
\nEn teor\u00eda, una inclusi\u00f3n con un di\u00e1metro de 10 micras entra en contacto con una burbuja, se adsorbe en ella y flota hasta la superficie del l\u00edquido.<\/p>\n

Durante el proceso de fundici\u00f3n, el aluminio met\u00e1lico reacciona con el vapor de agua para generar hidr\u00f3geno gaseoso, que se disuelve en el aluminio l\u00edquido. Cuando el aluminio l\u00edquido se solidifica, el hidr\u00f3geno gaseoso se separa del aluminio l\u00edquido.
\nIf the hydrogen content in the aluminum liquid is too high, the pores are easily formed in the casting, and the mechanical properties of the casting will be degraded. In severe cases, the castings will be scrapped. Hydrogen is a harmful gas in the aluminum liquid. The pre-furnace detection of the hydrogen content of the aluminum liquid is to ensure the quality of the casting. Important process.
\nEspecially in the precision die casting process, the use of aluminum liquid degassing tanks to remove hydrogen and slag will become indispensable.<\/p>\n

\"Desgasificador<\/p>\n

The degassing tank is specially designed for the online degassing of those flow tanks with large aluminum flow, high gas content and high inclusions.
\nWith Rotary rotor that can independently control the speed and gas flow, it can provide powerful degassing and refining ability for more aluminum liquid. The equipment is connected with the launder. The Rotary rotor of the equipment can be lifted as a whole and can be rotated at a certain angle. To facilitate the replacement of graphite accessories.
\nThe degassing tank corresponding to each Rotary rotor is provided with a separate slag slag port for easy slag slag separation. The well-insulated heat insulation design provides 24-hour online<\/p>\n
