he graphite rotor works by breaking nitrogen (or argon) blown into the aluminum melt into a large number of dispersing bubbles, which are dispersed in the liquid metal. Bubbles in the melt by 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 melt surface, so that the melt can be purified. Due to the small dispersion of bubbles, they are evenly mixed with the rotating melt, and then rotate to form a spiral shape and slowly float up. The contact time with the melt is long, and no continuous straight rising air flow will be formed, thus removing harmful hydrogen in the aluminum melt and significantly improving the purification effect. High strength graphite rotors can be used in the following industries:

Graphite crucible, as an indispensable machine and equipment for copper smelter and alloy copper, has excellent characteristics and is widely used in casting industry. To adhere to the excellent effect of graphite crucible, make full use of the advantages of graphite crucible, should pay attention to the operation method of high purity graphite crucible:

Binderless natural graphite powder can be cold-pressed under the pressure of 5~20 MPa. The density and strength of the mold increased with increasing pressing pressure, while the porosity and appearance change after heating at 1200 ° C decreased with increasing pressing pressure.

Graphite rotor is composed by two parts: rotor rod and impeller. Argon or nitrogen is blown into the aluminum melt through the rotor rod and impeller. The graphite rotor with high speed breaks up the argon of the aluminum melt to form many small bubbles and makes them dispersed in the metal liquid, and contacts with the bubbles to generate the adsorption principle to purify the solution. So, how do we maintain the graphite rotor?

The service life of graphite bearings, the service life of rolling graphite bearings is the number of revolutions (or the number of hours working at a certain speed). Definition: The graphite bearing in this life shall have initial fatigue damage (flaking or defect) on any graphite bearing ring or rolling body. But in laboratory experiments or theoretical applications, it can be clearly seen that the theoretical life of the same graphite bearings is different under the same working conditions.
