The monitoring system of the firebrick lining state of the blast furnace devil is offered. The mathematical description, algorithm and program of calculation the temperature fields in any vertical and horizontal cross-section of the devil lining are developed with use of the indications of the temperature sensing transducer (to 1000) in the oven lining. The systems of gathering, processing and information transfer from the temperature transmitters to a program database are used. This monitoring system is established on five blast furnaces of metallurgical plants of China.

The mathematical description and the computer program Devil Erosion of calculation the two-dimensional temperature fields in any vertical and horizontal section of the blast furnace hearth are developed. Calculation is carry out the decision of the equations of heat conductivity with use of indications of the big number of sensing transducers of temperature (to 1000), built in the furnaces firebrick lining between the firebrick blocks. The continuous control of the temperature change in each point allows to define the remained thickness the firebrick lining and to warn, in case of need, the furnace personnel about the beginning of the firebrick lining erosion. The continuous control of change of temperature in the firebrick lining is made on the basis of mathematical model. The system of collecting, processing and transfer information from sensing transducers of temperature or thermal streams in a program database Devil Erosion is used. Programs are installed on blast furnaces of Chinese National Republic: Jinan, Jiyuan and Liuzhou Iron and Steel Works.

The algorithm of a sensors arrangement in the blast furnace laying taking into account classification and the indications analysis of doubtful temperature sensors in 5 blast furnaces of the People's Republic of China is developed. When developing algorithm the adaptation of an arrangement of temperature-sensitive elements in a laying to the developed mathematical model of a laying heat [1, 2] for the purpose of minimization of their quantity and increase in reliability of indications at the expense of increase of density of their arrangement in the most dangerous zones of a laying and an exception of superfluous sensors in the zones being characterized by low degree of wear. The scheme of an arrangement of thermocouples for the blast furnace in volume of 5100 m3 is offered.

This paper presents a two-dimensional description of the temperature field in refractory lining of the hearth in the blast furnace. The mathematical model is based on Fourier differential heat conduction equation. Different solutions of this equation are presented and the optimal quantity and location of thermosensors in the hearth is proposed. This paper also presents a methodology to obtain the heat conductivity of refractory materials.
