Combining the spinning rotor degassing equipment self-developed for aluminum alloy melt

the influences of structure

size and location of the bluff body on the diameter

quantity and distribution of bubble were investigated by using the consecutive photographic technology of the digital camera.According to the experimental results

the desirable structure of bluff body is the cuboid

and the optimized ratio between the inner diameter of the crucible

the width and location of the bluff body is 6∶1∶0.7.The spinning rotor degassing equipment self-developed with the bluff body based on the optimized ratio was used to purify and degassing ZL101alloys.It is shown that the effect of purifying and degassing is excited.
