Density is generally default to 1.7g / cm3, our graphite rotor after antioxidant treatment density can be achieved 1.75-1.78g / cm3, making it long life.
Whether antioxidant treatment, depending on customer demand, the general needs of customers drawings.
The main input for the aluminum solution argon or nitrogen, and rotate 750 degrees below and strongly agitated molten aluminum, making aluminum melt into the argon or nitrogen to break up the formation of many small bubbles dispersed in the liquid metal, while rotating the rotor also contributed to hydrogen within the aluminum melt inclusions spread, making contact with the air bubbles in the melt by gas partial pressure and surface adsorption principle, to absorb the melt hydrogen adsorption oxide slag, and with the bubbles rise and was taken out of the melt surface, the melt to be purified.
1. Without contamination of impurities
2. High resistance to high temperature, lower down oxidation speed.
3. Excellent self-lubrication
4. Remarkable chemical corrosion resistance
5. High thermal conductivity and good thermal stability
6. Adequate mechanical strength and shock resistance
