Abstract:
We consider a strip of steel passing through a very long furnace which is heated by electric elements. Annealing of steel involves heating the steel to change its microstucture and such furnaces are used to accomplish this. The problem is to model the temperature within the furnace in order to control the annealing of the steel. A model developed at MISG 2004 for the furnace fails to predict a physical distortion of the steel that can occur near its edges. We look at various modifications of the model in order to explain this.
