System and method for dynamic process modeling, error correction and control of a reheat furnace

摘要

A system and method for controlling the temperature setpoints in a furnace such that a random mixture of slabs with different compositions, sizes, initial temperatures, temperature requirements, and anticipated residence times are all discharged at an appropriate temperature, with emphasis upon ensuring that no slab is insufficiently heated (rejected) per rolling and quality requirements. This is to be accomplished with minimized fuel use. This system can be implemented in a graphical programming environment, where real-time tuning, configuration, logic changes, model replacement, model retraining and other programming changes can be made without interruption of control.
