Abstract

Modern steelmaking processes require precise control of the slag operation in order to maximize mass and energy transformation efficiency and to minimize wear of the refractory lining in the metallurgical unit. Regular slag sampling and analysis is state of the art in modern melt shops, although slag optimization is sometimes neglected due to the additional effort and costs. In this paper, the assessment of mass balances and chemical analyses of slags in order to improve the metallurgical processes and lining lifetime in steel treatment ladles and EAFs are presented.
