Use of Alternative Carbon Sources for Slag Foaming in Electric Arc Furnaces

Аннотация

One of the current trends in resource saving in steel making is replacement of conventional carbonaceous materials by recycled carbonaceous materials (RCM), such as end-of-life tires containing carbon black. A “cold model” is used to study the foaming of steelmaking slag, the structure and morphology of products of thermal degradation of RCMs and their effect on the foaming process. The energy efficiency of the foaming process where conventional carbonaceous materials are partially replaced by RCMs is evaluated.
