Formation of optimal slag composition in ladle furnace for improvement of desulfurization properties and optimization of consumption of slag-forming materials
摘要
The objective of this study is to determine the optimal composition of slag formed in the ladle furnace unit with maximum desulfurizing properties. A method of calculating the refining properties of slag that takes into account the ionic nature of oxide melts is proposed. Based on the revealed regularities, slag compositions are selected depending on the technological operation of deoxidizing/alloying. As a result of the implemented measures, sulfur removal performance in the ladle furnace unit was improved, and the costs of slag-forming materials were reduced.
