Moblile Degassers

详情

Product features:
1. Aluminum and aluminum alloy melts contain a large amount of hydrogen, metal and non-metal inclusions; If the above harmful substances cannnot go in time before casting, casting defects such as porosity, inclusion, and looseness will be formed inside and on the surface of the casting, which will seriously affect the physical, chemical, mechanical and deep processing properties of the casting, and produce a large number of waste products.

2. The graphite rotor of the degassing equipment is placed in the alumininum melt, and the quantative refined gas is brought into the melt by a graphite rotor rotating at high speed; After the relatively high-speed shearing of the graphite rotor and the aluminum liquid, fine bubbles are generated and uniformly dispersed in the aluminum melt; Since the partial pressure of hydrogen in the bubble is zero, the partial perssure of hydrogen in the aluminum melt is high, wich promotes the hydrogen in the aluminum liquid to gradually diffuse into the bubble, and the metal and non-metallic inclusions in the aluminum liquid to gradually diffuse into the bubble, and the metal and non=metallic inclusions in the aluminum liquid are adsorbed on the surface of the bubble, and the bubbles and the carried inclusions float, so as to achieve the purpose of removing hydrogen and inclusions in the aluminum liquid.

3. It is suitable for pouring or cucible furnaces, using argon or nitrogen as the refining medium to remove hydrogen, metal and non-metallic inclusions form aluminum melt.
