前言为了测量炼铁高炉上部原料堆积状态(炉内料面轮廓),试用过多种方法。这种堆积轮廓和高炉燃料消耗的关系相当密切。现行的办法是,用被称作检尺的重锤式深度传感器来检测接近炉壁某一点的料面位置。但是,目前还没有能够测量高炉整个料面轮廓的实用装置。例如,虽然使用了重锤式深度传感器的多点机械式轮廓测量计也已在使用,但由于是接触式的,因此,测量精度不好,而且测量速度也慢。采用伽玛射线等辐射线的三角
Preface In order to measure the state of accumulation of the upper part of the blast furnace (surface profile of the furnace), several methods have been tried. The relationship between the accumulation profile and the blast furnace fuel consumption is quite close. The current solution is to use a hammer-type depth sensor called a ruler to detect the position of the surface near a point on the furnace wall. However, no practical device capable of measuring the profile of the entire blast furnace is currently available. For example, although a multi-point mechanical profilometer using a hammer-type depth sensor has also been used, the measurement accuracy is poor and the measurement speed is slow due to the contact type.
