摘　　要：介绍了一种改进型可变结构差温炉,借助双向智能伸缩与压紧结构设计模式,同一差温炉可实现对多种尺寸轧辊的热处理。基于变结构炉体,设计自适应时序脉冲燃烧控制程序,可针对不同轧辊尺寸与燃烧室容量自主调节控温区烧嘴工作时序,自动计算不同脉冲燃烧状态下的工作周期,实现烧嘴功率与脉冲时序的协调配合,从而有效达成控温目标。工程应用表明:可变结构差温炉可以满足多种型号轧辊的热处理需求,节约设计成本;自适应脉冲燃烧方法可有效提高炉温分布均匀性与控温精度。An improved variable structure differential temperature furnace is introduced.With the help of a bidirectional intelligent expansion and compression structure design mode,the same differential temperature furnace can achieve heat treatment for multiple sizes of rolls.Based on the variable structure furnace body,an adaptive timing pulse combustion control program is designed,which can independently adjust the working timing of the temperature control zone burner for different roll sizes and combustion chamber capacities,automatically calculate the working cycle under different pulse combustion states,achieve the coordination of burner power and pulse timing,and effectively achieve temperature control goals.Engineering applications show that the variable structure differential temperature furnace can meet the heat treatment needs of various types of rollers and save design costs;the adaptive pulse combustion method can effectively improve the uniformity of furnace temperature distribution and temperature control accuracy.
