A Simple Slab Temperature Model

• The model presented in this paper has been used for predicting the slab core temperature in several applications at The Danish Steel Works Ltd. The model has the advantages that it is simple and only contains a minimum of physical parameters, which makes it easy use and adapt to slab temperature measurements. The model has been verified using 11 data sets covering three different slab thicknesses and two different furnaces. The model is used for on-line prediction of the slab temperature of furnace no. 1 and has been used for redesigning the slab temperature control algorithm for furnace no 2. at The Danish Steel Works Ltd. Both applications has lead to significant improvements in the performance of the furnace and the rolling mill control systems.
