摘    要：以国内外烧结过程控制技术发展状况为背景,论述了烧结过程智能优化控制的方法及应用,即烧结配料优化方法和烧结过程热状态优化控制(包括烧结终点控制和点火燃烧控制)。分析了上述三个优化控制问题的复杂性,指出了采用模糊控制、神经网络、专家系统等智能方法可以实现烧结过程的优化控制。将提出的智能优化控制方法应用于工业现场,运行结果表明:该方法不仅能在满足烧结矿质量要求的前提下,有效降低配料成本,而且显著改善了工况波动情况,提高了烧结机利用系数及烧结矿质量指标,降低了燃料消耗。最后简要展望了烧结过程控制技术今后的发展方向。

Abstract: Based on current development of sintering process control technology,intelligent optimization and control methods and applications to sintering process are dissertated including sintering burdening optimization,burn-through point(BTP) control and ignition combustion control.Analyzing the complexity of above-mentioned three control and optimization problems,it is pointed out that intelligent methods,such as,fuzzy logic,neural netwalk and expert system,are efficient to the control and optimization of sintering process.These methods are applied to industrial field and operation results show that burdening cost is reduced without sacrificing sinter quality,utilization coefficient of sintering machine is increased,sinter quality index is enhanced,fuel consumption is reduced,and great economic benefits are created for steel company.Finally,development direction of sintering process control technology is prospected.
