The mathematical model of thermal processes in a hearth laying of the blast furnace allows on the basis of temperatures data in the fixed points of a laying is developed to determine a temperature field on height and radius of fireproof lining and on the basis of the received information to define a furnace hearth profile. The developed mathematical model is realized in the software introduced in the operating metallurgical units for an assessment of a condition of fireproof lining of a blast furnace hearth. Introduction is carried out in five blast furnaces in the People's Republic of China with registration of the relevant acts. Due to universality of the developed mathematical model its software can be introduced in blast furnaces where other models of creation of a fireproof lining wear on the basis of indications of temperature sensors in a laying as the main or duplicating system are already used. In particular, the model was used for an assessment of a condition of a blast furnace No. 5 of Nizhniy Tagil Iron and Steel Works. As a Keynote Paper.
