Szilícium-nitrid Si3N4 kerámia D-gázosító tengely alumínium-feldolgozó iparhoz

Product Details

The working principle of the degassing rotor is that the rotating rotor breaks the nitrogen (or argon) gas blown into the aluminum melt into numerous dispersed bubbles and distributes them throughout the liquid metal. These bubbles absorb hydrogen from the melt and adsorb oxides and inclusions. As the bubbles grow, they rise to the surface of the melt and are expelled, thus purifying the melt and effectively removing harmful hydrogen from the aluminum melt. 

Compared to graphite rotors, silicon nitride (Si3N4) ceramic degassing rotor shafts exhibit excellent wear resistance and oxidation resistance. These properties ensure efficient and stable hydrogen removal during prolonged use, significantly reducing the frequency of component replacements and thereby lowering costs. 

Mascera offers both standard and customized silicon nitride ceramic degassing rotor shafts to meet various customer requirements. The structural design of the rotor impeller promotes uniform gas distribution within the molten aluminum, minimizes turbulence caused by the gas, and prevents vortex formation. This superior gas dispersion capability significantly enhances hydrogen removal efficiency, improving the quality of castings.  hydrogen removal efficiency, improving the quality of die cast components.
