Investigation of Bath/Freeze Lining Interface Temperature Based on the Rheology of the Slag

Abstract Freeze lining is a solidified layer of slag formed on the inner side water-cooled pyrometallurgical reactor, which protects reactor walls from thermal, physical, and chemical attacks. Because freeze lining's high thermal resistance, heat losses strongly depend thickness. In batch process such as fuming, conditions change with time, affecting Determining thickness challenging it cannot be measured directly. this study, conceptual framework based morphology microstructure rheology discussed experimentally evaluated to determine It was found that bath/freeze interface lies just below critical viscosity temperature. The growth primarily controlled by mechanical degradation crystals forming at interface. temperature for in range 1035–1070°C.
