The New Method for Fast Testing of Surface Tension of Liquid Alloy and Its Application in Foundry Production

摘要

Surface tension of liquid alloy relates to solidification of liquid alloy, inoculation and refining effect. In order to fast evaluate the quality of liquid alloy by surface tension, a new method and a new device for fast testing of surface tension have been developed by authors. In the paper, the principle of the new method and device and their application in graphite shape identification of cast iron and inoculation effect evaluation of aluminium alloy were introduced.
