Study of the Hydrodynamics of a Trof Converter by Numerical and Cold Modeling

摘要

Results are presented from a study made of the hydrodynamics of the liquid bath in a TROF converter to find efficient operating parameters for conducting the blow through an unsubmerged lance. The study was performed on a cold physical model. Investigation of the character of development of the blast jet in the bubbling zone made it possible to establish the main forces associated with the mass of the liquid, friction, and buoyancy and to thus determine the hydrodynamics of the liquid bath.
