摘　　要：介绍了炉窑控制的当前状况、发展趋势和新的技术方法;详细论述了燃烧控制及交叉限幅工作原理,给出典型控制结构图和限幅器算法及适用范围,并分析其中参数对性能的影响;介绍了热值仪比值优化、热处理炉低温控制和孔板量程修正;讨论了温度设定数学模型,并结合实际描述一套棒材加热炉温度数学模型,其中包括时间待轧和自动待轧策略。The paper introduces the furnace control about the current status, developing trend and new technique. The combustion control, and the principle of dual-cross limiter are discussed, typical control structure and limiter algorithm for their targets are given, as well as the effect of parameters on the quality is analyzed. Meanwhile the ratio optimization with thermo-value meter, the low temperature control and orifice scale-correcting for treatment-heating furnace are introduced. Finally the temperature setting model is discussed, by combining the practice, a kind of temperature model with the strategy of time-wait-rolling and auto-wait-rolling for steel bar heating furnace is described.
