REFRACTORY PRECAST SHAPES FOR ALUMINUM DE-GASSING SYSTEM
The degassing device is installed in the middle of the aluminum melt casting launder, usually between the furnace discharge port and the filter box, and carries the quantitative refining gas into the melt through the high speed rotating graphite rotor; the relatively high speed of the graphite rotor and the aluminum liquid Shearing, producing fine bubbles and evenly distributed in the aluminum melt; since the hydrogen partial pressure in the bubbles is zero, the hydrogen partial pressure in the aluminum melt is high, and the hydrogen in the aluminum liquid gradually diffuses into the bubbles; meanwhile, the aluminum liquid The metal and non-metallic inclusions are adsorbed on the surface of the bubble, and the bubbles and inclusions float up; thereby achieving the purpose of removing hydrogen and inclusions in the aluminum liquid.
Performance requirements for refractory materials for gas removal tanks:
Good volume stability
Good thermal shock resistance
Not easy to crack
Excellent resistance to aluminum water penetration
