Abstract
AbstractBurden distribution affects the whole process of iron-making in a blast furnace (BF), including the distribution of the gas flow, the quality and production of the pig iron, and the consumption of the energy. Gas utilization rate (GUR) is one of the most important indictors to reflect the development of a BF. Designing a control strategy of the burden distribution for the GUR is necessary to improve the utilization of the gas flow, increase the production of the pig iron, and decrease the consumption of energy. Thus, this chapter introduces methods to predict and control the trend of the GUR. First, this chapter introduces the iron-making process of a BF. Based on this, this chapter introduces the development and the influencing factors of the GUR. Meanwhile, this chapter introduces the burden distribution and its impact on the gas flow and GUR. Then, this chapter introduces three different models to predict the GUR, which consider the chaotic characteristic of GUR, the qualitative influence of the operations on the development trend of the GUR, and the quantitative influence of the operations on the value of the GUR, respectively. Finally, this chapter introduces a decision-making strategy to improve the development trend of the GUR. According to some simulations, these methods predict the GUR accurately and change the development trend of the GUR qualitatively.KeywordsIron-making processGas utilization ratePrediction modelDecision-making strategyBurden distribution
