为了连续测定烧结混合料、焦粉和高炉灰的水分,美国内陆钢铁公司对电阻湿度计、核子湿度分析仪和红外线湿度分析仪三种设备进行了比较;并决定选用红外线湿度分析仪,为了用这种设备连续、精确和可靠地测定上述三种物料的水分要安装专用装置,并进行校正(批量或连续),以及必要的维护。采用这种四束射线(QB)红外线湿度分析仪”时,烧结混合料的水份波动值可控制在±0.25‰。如果烧结混合料的水份合适,在这种条件下,烧结机的产量可增加5.6%而对烧结矿的质量没有影响。采用红外线连续测定焦粉和高炉灰的水份,并进行补偿,可便于按干量计算将这两种燃料添加到混合料中去。这种控制燃料的方法,可降低燃料消耗,改善烧结操作。
In order to continuously determine the moisture content of the sintering mixture, coke powder and blast furnace ash, the Continental Steel Company compared the three devices of resistance hygrometer, nuclear humidity analyzer and infrared humidity analyzer; and decided to use the infrared humidity analyzer, in order to Continuous, accurate and reliable determination of the water content of the above three materials with this equipment requires the installation of special equipment, and calibration (batch or continuous), as well as the necessary maintenance. With this four-beam (QB) infrared moisture analyzer, the moisture fluctuation of the sinter mix can be controlled to ± 0.25 ‰. If the moisture content of the sinter mix is adequate, the output of the sinter Can increase 5.6% without affecting the quality of sinter.Using infrared continuous determination of coke and blast furnace ash water, and compensation, can be easily calculated by the dry weight of these two fuels added to the mixture to go.This The method of controlling the fuel can reduce the fuel consumption and improve the sintering operation.
