Strip Temperature in a metal coating line annealing furnace

We discuss the work done at MISG 2004 on the mathematical modelling of a long, electric radiant furnace used to anneal strips of steel. The strip is passed continuously through the furnace. The annealing process involves heating the steel to certain temperatures and then cooling it, resulting in a change in the crystalline structure of the steel. The furnace settings are often changed to cater for products with different metallurgical properties and varying dimensions. The mathematical model is desired to optimise the running of the furnace, especially during periods of change in furnace operation.
