Abstract

Gas bubbling and flux injection processes have been extensively used in metallurgical industries for several decades since the processes have been confirmed to be effective in removing impurity elements and non-metallic inclusions from liquid metals and improving the morphology of inclusions. Aiming at more effective use of gas and flux powder for injection refining to obtain higher quality products at lower cost, elucidation of the interfacial phenomena at inert gas-solid particle-liquid metal interfaces has become increasingly important. A new technique is presented to observe in situ the inclusions on steel melt, revealing collision/agglomeration characteristics of the inclusions.
