Comparison of Modeling Methods for Reheating Furnace

The first problem of furnace modeling is the form of furnace temperature distributing. The cubic distributing form is proposed by analyzing other two forms whose advantages are colligated. It can truely reflect furnace's situation and make the optimized enactment convenient. Three methods for steel temperature estimation are discussed with analyzing difficulties, algorithm's astringency, real time character, model's self-adaptability and so on. The furnace model of some steel company is established by mechanical analyzing, and the nonlinear model is translated into a linear one. A reasonable method is proposed by analyzing the reason of morbidity data. The test result shows model's simpleness and practicability, and a good base is got ready for the optimized enactment.
