Skull Formation

Modern production processes of high alloyed and stainless steel grades are subject to the cost-optimized production of raw steel or molten combined with high flexibility. Excellent mixing of the steel melt helps to improve mass and heat transfer in the EAF, in order to accelerate the melting of heavy scrap and alloys, decarburization, homogeneous superheating, alloy distribution, and to avoid skull formation and solid remainders that may obstruct tapping. The RADEX DPP system generates customer benefits by improving EAF processes during high-alloyed stainless steel making. The most important effect of the enhanced steel bath mixing besides improved heat transfer and decarburization is a decreased chromium oxidation. Firstly, chromium oxidation is decreased by improving the homogeneous distribution of carbon and chromium in the melt. Secondary, build-up of chromium-containing solids in the EAF hearth and skull formation is decreased by stronger melt movement. The cost savings of both effects economically justify the application of gas purging in EAF stainless steelmaking. Case studies are presented demonstrating the advantages. Ill.7. Ref. 7. Tab. 3.
