| Abstract: | Effect of Na 2CO 3 on the fluidity of liquid aluminum for green sand casting was invesitgated, and the mechanism was analyzed. It is concluded that basicity of molding sand increases and fluidity of liquid aluminum decreases with the rising of Na 2CO 3 content in sand mold, and increase of interface tension of molding sand liquid aluminum causes fluidity of liquid aluminum to decrease. |

| Keywords: | liquid aluminum Na 2CO 3 fluidity interface tensioin |
