提高高炉风温不仅直接影响生铁产品的产量和质量,而且是高炉提高煤比(增加喷煤量)和降低燃料比(焦比)的重要措施之一。从热工角度初步分析了高炉热风炉的热工行为;在此基础上,根据热工炉窑3类变量之间的关系,系统分析了热风炉结构参数和操作参数对其出口风温的影响;指出了如何从结构参数和操作参数上提高高炉热风炉风温。
Blast furnace air temperature not only directly affects the output and quality of pig iron products, but also the blast furnace to improve the coal ratio (increase the amount of coal injection) and reduce the fuel ratio (coke ratio) an important measure. Based on the analysis of the relationship among the three types of variables in the thermal furnace, the influence of the structural parameters and operating parameters of the hot blast furnace on the outlet air temperature was systematically analyzed. ; Pointed out how to improve the blast furnace air temperature from the structural parameters and operating parameters.
