This paper is based on the heating furnace of Zhao-feng Steel Works, Chengde, and according to the characteristics of the research object, use the method that the mechanism analysis combining with the discrete state space method to build billet one-dimensional mathematical model of steady-state heat conduction. Setting up the objective function of the minimum fuel consumption, taking billet baked surface temperature, the maximum cross-sectional temperature, heating rate and furnace temperature settings as constraints obtained and using a variable tolerance method to obtain the furnace temperature settings for each segment. When the output is constant, the optimal allocation of heat load along the longitudinal direction can be obtained by this model, which has a good guidance for the actual production. |
