Over recent years, the need to increase productivity in blast furnaces has necessitated an increase in the hot metal temperature, which subsequently intensifies the wear of refractory linings. While there are numerous publications that present comparative tests on hearth refractories, there is a notable deficiency in the literature regarding the underlying reaction mechanisms and the progressive deterioration of these materials. This study aims to identify various reaction mechanisms and enhanced refractory lining deterioration by conducting comparative laboratory tests using two different carbon materials. The results highlight the significant wear mechanisms impacting hearth lining, such as increased liquid flow rates causing accelerated wear processes like 'elephant’s foot' in the tap hole area, and an increased rate of pulverized coal injection leading to reduced permeability and turbulent hot metal flow. Based on the insights gained regarding these wear mechanisms, the study proposes practical operational measures to extend the lifespan of blast furnace campaigns.
