Abstract: | An impinging gas jet on a molten bath having a slag layer on top is encountered in various metal processing operations. The
impinging region was studied using a physical model consisting of an air jet and water bath. Kerosene and corn oil were used
as the second layer to investigate the role of the slag layer properties on interface shape and bath circulation. The interface
shapes were measured both photographically and by using a surface-tracking resistance probe. The limiting condition at which
the jet breaks through the kerosene or corn oil layer and reaches the water layer was determined experimentally. A phenomenological
model for the prediction of penetration depth is developed for both short and long jet heights for liquid baths with and without
a second liquid layer on top. |
