| Abstract: | Surface tension is one of important physical properties of melt, and it will affect the forming process of castings. The importance of testing melt surface tension has been attached gradually by metallurgists and foundry men. In this paper, the frequently used methods and devices to test melt surface tension were introduced, and the research tendency was discussed as well. It was pointed out that the main research fields in the future may be on-the-spot testing, high precision static testing and surface tension calculating technology. |
