为了控制烧结矿的产量和质量,烧结料层燃烧带的特性是很重要的。所以,研制了一种加热曲线的连续测定装置。通过这种裝置的应用。大概能作25个周期的加热曲线的测定。这种装置由三个部分组成,即一带金属套的热电偶、防护装置及其遥测装置。用这种裝置所获得的加热曲线,有两个指数,即O值和CT值。O值是用900℃以上的积分温度曲线估算的,而CT值是根据达1100℃的峰值温度的冷却速度估算的。到目前为止,应用这种装置所测得的结果可以归纳为如下两点: 1) Q值与落下强度之间存在着相互关系; 2) 烧结矿中FeO含量和CT值与烧结料层的峰值温度间存在着简单的相互关系。
In order to control the yield and quality of the sinter, the characteristics of the sinter zone of the sinter bed are important. So, developed a continuous heating curve measurement device. Through the application of this device. Probably for 25 cycles of heating curve determination. This device consists of three parts, namely a metal sleeve thermocouple, guards and telemetry devices. The heating curve obtained with this device has two indices, O and CT. The O value is estimated with an integral temperature curve above 900 ° C, and the CT value is estimated from the cooling rate at a peak temperature of up to 1100 ° C. So far, the results measured using this device can be summarized as follows: 1) there is a correlation between the Q value and drop strength; 2) the content of FeO and the CT value in the sinter and the peak value of the sinter bed There is a simple correlation between temperatures.
