Experimental study on the foaming phenomena in a non-reacting system

The phenomena of foaming in smelting reduction processes has been studied using air-soap solution non-reacting system. It is necessary to study its fundamentals as the control of slag foaming to certain extent is very much desirable for the present iron and steel making processes. This study is concerned with a model study of foaming characteristics when air is passed through a non-reacting soap solution system. Although the soap solution-air system does not necessarily simulate with the actual happenings during in-bath smelting operation at elevated temperatures, it provides with the basic understanding of various factors through which the phenomena of foaming could be expressed. The effects of various operating parameters like foam height, foaming index, foam life, superficial gas velocity etc, on the foaming phenomena height, foaming index, foam life, superficial gas velocity etc, on the foaming phenomena make the present fundamental study on foaming characteristics a significant one.
