Test method for stratified analysis of magnetizing roasting effect of blocky iron ore

The invention provides a test method for stratified analysis of a lump iron ore magnetizing roasting effect, and aims at solving the problems existing in lump iron ore shaft furnace magnetizing roasting. On the basis of researching the relationship between the blocky iron ore magnetizing roasting effect and magnetizing roasting temperature, time and reducing gas components, the method comprises the following steps: cutting and layering roasted ores, taking surface layer and center roasted ore samples, respectively detecting the TFe and FeO contents, calculating the blocky iron ore magnetizing roasting unevenness, and carrying out layering analysis on the blocky iron ore magnetizing roasting effect. And a technical support is provided for optimization of lump iron ore shaft furnace magnetizing roasting process parameters. 本发明提供了一种分层分析块状铁矿石磁化焙烧效果的试验方法，针对块状铁矿石竖炉磁化焙烧存在的问题，利用实验室竖式电炉模拟竖炉磁化焙烧工艺，在研究块状铁矿石磁化焙烧效果与磁化焙烧温度、时间和还原气体成分之间关系的基础上，对焙烧矿进行切割分层处理，取表层、中心两种焙烧矿样，分别检测其TFe、FeO含量，计算块状铁矿石磁化焙烧不均匀度，分层分析块状铁矿石磁化焙烧效果，为块状铁矿石竖炉磁化
