A method is provided for on-line monitoring of the wear of a refractory lin- ing of a blast furnace. The method in- cludes determining the wear line of the lining from signals provided by tempera- ture probes located in groups, e.g., group (10, 12, 14), group (16, 18, 20), group (22, 24, 26), embedded at spaced loca- tions across the thickness of the refractory lining. Other methods disclosed include: a method of determining the thickness of a protective layer of solidified metal skull formed on the refractory hearth, a method of determining the conditions of heat trans- fer between a refractory lining and a metal shell of a blast furnace and between the metal shell and cooling water applied to the shell, and a method of extending the life of refractory lining.
