Abstract
Results are presented from an analysis of the temperature of the lining in the shaft and bosh of a blast furnace over a 2.5-year campaign. It is shown that changes in the temperature of the lining over the height and about the circumference of the furnace are affected by changes in the parameters of the raw materials and the smelting process. For example, lining temperature is affected by changes in the charging program, the amount of manganese-bearing materials in the charge, the number of closed tuyeres and their locations, the quality of the charge materials, the chemical and component-by-component composition of the iron-ore-bearing part of the charge, and the distribution of the components of the charge across the furnace.
