AI Technical Summary
The existing aluminum liquid refining rotary mechanism has a simple rotor structure, insufficient stirring effect, insufficient vortex strength, limited bubble dispersion effect, low hydrogen removal efficiency, and aluminum liquid easily sticks to the rotor surface, making cleaning difficult and affecting the refining effect.
Impellers, vertical grooves, and rotating grooves are installed on the rotor, and baffles and nozzles are installed on the rotating rod to control the nitrogen spray angle, forming fine bubbles, enhancing the stirring effect, and reducing aluminum liquid adhesion.
It significantly improves hydrogen removal efficiency and slag removal effect, enhances the mixing reaction efficiency of aluminum liquid, reduces the content of hydrogen and oxide inclusions, and improves the mechanical properties and fatigue life of wheel hubs.
