摘　　要：燃烧控制是实现均热炉群优化控制的基础 ,而燃烧控制的核心是空燃比控制。但煤气热值波动、换热器漏风等现象均会影响空燃比的准确性。笔者从理论上分析了影响空燃比的诸多因素 ,并根据各影响因素的特点 ,综合运用专家系统等方面的知识 ,开发和建立了宝钢初轧厂均热炉群最佳空燃比寻优控制系统。The basis for realizing the optimizing control of soaking pits is combustion control, the key in which is to control the ratio of air to fuel. But the accuracy of the ratio of air to fuel is reduced by some phenomena such as the fluctuation of heat value of gas, the air leakage of heat exchanger and so on. The factors that have influence on the ratio of air to fuel are theoretically analyzed in detail and the control system for optimizing ratio of air to fuel of soaking pits is developed by use of expert system.
