摘　　要：针对合金板带产品在热处理加热过程中对燃烧气氛稳定性、炉温均匀性和控温精度、加热质量等指标要求较高的特性,深入研究脉冲燃烧控制技术,介绍了脉冲燃烧控制的技术特点及系统组成,探讨了特钢大型高温热处理炉上使用的脉冲燃烧控制模型的原理及特性。该炉采用的脉冲燃烧控制技术具有系统安全可靠、运行稳定、控制灵活、精度高的特点,保证了钢板热处理的高质量和稳定性。As the heat treatment process of alloy strip products puts high requirements on the stability of combustion atmosphere, uniformity of furnace temperature, accuracy of temperature control and quality of heating, the pulse combustion control system is studied systematically and the technical features and system composition of pulse combustion are introduced. In addition, the principle and characteristics of the pulse combustion model adopted in the large-scale high temperature heat-treatment furnace for special steel are analyzed. The application results show that the pulse combustion control system is reliable, stable, flexible and precise, which ensures the quality and stability of the heat treatment of plates.
