Influence of FeO content on slag viscosity during splashing. Increasing the resistance of the refractory lining [33-37]

Is this work devoted to one of the most important areas of energy and resource conservation in metallurgy? utilization of converter slag and, as a result, an increase in the resistance of the refractory lining. Studies are presented in which, based on the chemical composition of the slag of the Polish metallurgical plant, using the Riboud and Urbain models, the dynamic viscosity of the slag was determined in the temperature range from 1500 to 1650 ° C, as well as a comparative analysis with the results of the Fact Sage program. In addition, the results of a calculation are given, which allows, with a variable FeO content in the slag from 5 to 30%, to determine its effect on the viscosity of the slag.
