Development and Introduction of Monitoring System of Refractory Lining Wear in Blast Furnace Hearth

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.

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.
