This paper investigated a prediction model for slab temperature, a zone temperature setpoint strategy and a dynamic complement method to reduce energy consumption and improve slab heating quality by walking beam reheating furnaces. The model is based on the two-dimensional partial differential equations describing both the unsteady state heat conduction and the corresponding boundary conditions of the heated slab. Hooke-Jeeve method is adopted in solving the optimization problem. PID regulation and expert experiences are applied to the dynamic compensation procedure. Effectiveness of the strategy was verified through simulations.
