In a steel refining process, droplets of various sizes are usually generated in the atmosphere above the bath of a top-blown converter. There are two generation mechanisms of droplets which are called splash (made of large droplets) and spitting (made of fine droplets), respectively. In the top-blown converter, molten slag (low density) is placed on the molten metal (high density) so that the metal droplets generated can contain the slag in itself. The amount of molten metal contained in the droplets is responsible for metal loss and refining efficiency. It is therefore of practical importance to predict the amounts of molten metal and slag contained in the droplets which are generated by the splash and the spitting. This study proposes the prediction method of slag concentration in droplets generated in the top-blown converter based on water-model experiment.
