| Abstract in different language: | Numerical simulation of industrial reheating furnaces belongs to important procedures for an optimization of their designand processing parameters. A 3D numerical model of a continuous gas burners heated walking-beam furnace is introduced in this paper. The main benefit of the model is a compromise between its complexity and computing speed. The model connects numerical procedures and empirical knowledge. It is based on a Hottel zonal method and a compartment based solution of heat transfer process in solids. It allows specifying charge, heating system and furnace parameters. The solution includes convective and radiative heat transfer in the furnace including a participation of a semi-transparent gaseous furnace atmosphere. A direct measurement of charge temperature course in a walking-beam furnace using thermocouples and thermal box-barrier are introduced. Comparisons of the measurement results with results of numerical simulations are presented. Connection between direct measurement in the furnace and the numerical simulation parameters is discussed. A good agreement between the theoretical and measured data shows, that the model includes the most important physical process. |
