What are the product characteristics and working principle of graphite rotor?

February 01, 2023

Product features: 1, suitable for crucible furnace, casting bag, static box of liquid aluminum purification treatment 2, degassing rate of more than 50%, shorten smelting time, reduce production costs. 3. Rotary essence degasser is divided into mobile and fixed modes, which are suitable for different operating environments.

Graphite rotors work by rotating rotors that break nitrogen (or argon) in the blowing aluminum melt into a large number of dispersing bubbles that disperse in the liquid metal. The gas bubble in the melt depends on the gas differential pressure and surface adsorption principle, absorb the hydrogen in the melt, adsorption oxidation slag, and with the bubble rise and be taken out of the surface of the melt, so that the melt can be purified. Because of the subtle dispersion of bubbles, they are evenly mixed with the rotating melt, and then rotate in a spiral shape and float slowly. The touch time with the melt is long, and it will not form a continuous straight rise of the air flow, and then significantly improve the purification effect.
