Desulphurization of Hot Metal – IspatGuru

Oct 16, 2013· Desulphurization slag contains about 50 % iron. The loss of heat during the desulphurizing process is an important factor since it reduces the sensible heat of the hot metal sent to the converters. The three primary sources of heat loss are radiation from the surface of the hot metal, addition of cold reagents and introduction of cold injection ...
