Abstract
Temperature field of steel billets is the most important value for control of the furnace during the reheheating process. This is a non-measurable value. The only way to get this value for control purposes is to develop real-time simulation model of the steel reheating process. Fast-enough algorithms are required to describe complex mechanisms which occur during the reheating process. The aim of the project is to develop algorithms for real-time simulation of the reheating process.
Thermal radiation is a dominant mode of heat transfer in high-temperature reheating furnaces. The carbon dioxide and water vapour formed, as combustion products in the furnace enclosure are significant emitters and absorbers of radiant energy. The geometry of the furnace with charged billets represents complex geometry for thermal radiation calculation. Therefore conventional methods for calculating thermal radiation heat exchange became useless. Problems in thermal radiation are particularly well suited to solution by Monte Carlo (MC) method, since energy travels in discrete particles (photons). This method will be used to treat the enclosure of complex geometry. This method is numerically very intensive and cannot directly be applied in real-time model
The idea for real-time simulation using MC is to divide thermal radiation heat transfer into geometry part (view-factors) and to energy part. The main time-consuming operation in thermal radiation heat transfer is to calculate view-factors. The geometry part will be calculated by MC before the simulation and written in the form of view-factor matrix.
The heat net-heat flux to each suface or volume element in the furnace can then be calculated by coupling this matrix by vector of emitted heat fluxes. This operation is expected to be calculated in real-time. These net-heat fluxes will be used as boundary conditions to heat conduction model, which is going to base on the 3D finite difference method.
