A transient thermal model was developed for slab furnaces in Eregli Iron and Steel Works(Erdemir)in Turkey and the model was solved using the FlexPDE computer program.This program uses the finite element method.Program codes were written to solve the temperature distribution of slabs that are put into furnace at 25 ℃ and removed at about 1 250 ℃.To obtain the optimum slab exit temperature variation,the necessary air temperature inside the furnace was calculated to be 1 390 ℃.The slab temperature versus time and the temperature variation inside the slab were depicted.
A transient thermal model was developed for slab furnaces in Eregli Iron and Steel Works (Erdemir) in Turkey and the model was solved using the FlexPDE computer program. This program uses the finite element method. Program codes were written to solve the temperature distribution of slabs that are put into furnace at 25 ° C. and removed at about 1 250 ° C.To obtain the optimum slab exit temperature variation, the necessary air temperature inside the furnace was calculated to be 1 390 ° C. The slab temperature versus time and the temperature variation inside the slab were depicted.
