Abstract

Mold powders are easily entrapped in the molten steel and become one of the main sources of the troubles such as frange cracks in DI cans. It is important to know how the mold powders are entrapped and how to aviod these. In order to clarify the phenomena, a hydrodynamical analysis which treated the molten steel flow from the tundish to the mold has been made. The results of such an analysis were checked by some tests which were accomplished by a water model and by the YAWATA No. 3-CC plant. This can be concluded as follows:
(1) The analytical surface velocities and experimental ones show a good fit.
(2) The analytical surface velocities can be used as one of the most useful quality control parameters to classify the grades of the products.
