    摘要: Gas is dispersed into molten metal by immersing a shaft-­supported impeller (20, 40) into the molten metal and by pumping gas through the shaft (40) and out of the impeller (20). The impeller (20) is in the form of a rectangular prism having sharp-­edged corners (39) that shear the gas into finely divided bubbles. The particular shape of the impeller (20) provides an especially effective bubble-shearing and bubble-dispersing action.
