Zero impurity contamination to molten aluminum.
Superior high-temperature resistance to slow down oxidation rate.
Excellent self-lubricating performance.
Remarkable resistance against chemical corrosion.
High thermal conductivity and good thermal-shock stability.
High mechanical strength and impact resistance.
Operating at temperatures up to 750 °C, the graphite rotor vigorously agitates molten aluminum with continuous injection of argon or nitrogen. Rotational motion breaks the introduced gas into large quantities of micro-bubbles uniformly dispersed throughout the liquid aluminum. Meanwhile, rotation accelerates the diffusion of dissolved hydrogen and solid inclusions within the melt. Following gas partial-pressure difference and surface-adsorption principles, hydrogen and oxide slag are captured by the micro-bubbles. The contaminants float upwards together with bubbles to the melt surface for skimming, thus completing efficient purification of aluminum melt.
