METHOD FPR DETERMINING THE LIMITING WETTING ANGLE METHOD FPR DETERMINING THE LIMITING WETTING ANGLE OF MELTED METAL OF MELTED METAL

摘要

The present invention relates to a method for determining the limiting wetting angle of melted metal by the shape of a metal drop disposed on a solid plate. The metal drop is formed by pressing out melted metal through a vertical tube after the formation of oxide film on the internal surface of the tube.
