Abstract: With the improvement of smelting intensity, the converter equipment is subjected to higher thermal loads, causing thermal failure and reduction of the working life. It is crucial to analyze the temperature distribution in the converter to achieve the optimum one. This paper proposed to develop a full-scale mathematical model of a 150-ton steelmaking converter consisting of the furnace, trunnion ring, suspensions and brackets to accurately reflect the distribution of heat sources. The actual working characteristics of the converter, nature of boundary conditions, and temperature-dependent thermal conductivity of materials were considered in the analysis. The thermal parameters used in the mathematical model were identified by an iterative inverse method. The steady-state heat transfer behavior of the converter was performed in a thermo-solid coupled manner using three-dimensional (3D) finite element method (FEM). The numerical results were validated experimentally. The simulation results indicated that the maximum temperature of the furnace shell was 378 °C. A high-temperature zone appeared in the center of the cylindrical section. The furnace shell temperature was found to be strongly correlated to the lining thickness. The radiation heat from the furnace shell caused a significant temperature gradient in the trunnion ring cross-section. The simulation results also showed that the cooling water velocity had a notable influence on the trunnion ring cooling efficiency. The present study can provide theoretical guidance for the engineering design of the converter, and the modelling strategies can be extended to characterize the temperature field of high-temperature steelmaking equipment.
