Abstract

Components were developed for the modeling of industrial furnaces in the iron and steel industry like pusher-type and walking beam furnaces. A cell model on the basis of the dynamic pipe model of the Modelica Fluid Library was designed. The cell model computes the heat transfer between furnace walls; flue gas and the processed steel goods. The radiative heat transfer is modeled by a 1-dimensional method based on Hottel’s net radiation method. Furthermore; models for furnace walls; slabs; hearth and the transport of the slabs were designed. The models are suitable for analyzing operation modes and designing control concepts.
