Research On Intelligent Control For Walking Beam Furnace

With the development of our country socialist market economy, the iron and steel enterprises in the development of the national economy plays a more and more important position. The author of this writing process, is the key to Shougang Group Shougang Group as a case, is the history of our country development is relatively long in an enterprise. It was founded in 1919; with the development of new China has been changing history. This paper introduces the structure and technology of the reheating furnace of Capital Steel Group (Corp.).The paper proposes an intelligent control strategy of the combustion process of reheating furnace, including the fuzzy expert control strategy based on the fuzzy expert rules, according to the technical characteristics of walking beam reheating furnace. The intelligent optimal control system is also established in this paper, fulfills the collective scrutiny in the operation process of reheating furnace, and has the prominent economic and social benefits.The fuzzy expert control strategy based on the valve value in the paper obtains the flux from the temperature warp, the warp ratio and the air-gas ratio. The valve value achieved from the model of the relation between flux and valve value. Meanwhile, the paper has proposed and air gas ratio optimal strategy for the thermal value fluctuation of the gas, has established the prediction model of billet temperature for the furnace temperature optimization with the ameliorated BP neural network model, The practical operation result in the industry offers the evidence that the burning process intelligent control system of reheating furnace can assure the delicacy of the furnace temperature control. The control system increases the speed of temperature adjustment and reduces the energy consume, electricity consumption and the billet combustion loss. As a result, it elevates the productive capacity of reheating furnace, fulfills the collective scrutiny in the operation process of reheating furnace, and has the prominent economic and social benefits.
