标准摘要
[中文适用范围]： 本文件规定了一种方法，为评估铁矿石在类似于竖井直接还原工艺中普遍存在的条件下还原时的尺寸退化程度和金属化程度提供相对测量。 本文件适用于块矿和热粘球团矿。 [外文原描述]： This document specifies a method to provide a relative measure for evaluating the degree of size degradation and degree of metallization of iron ores, when reduced under conditions resembling those prevailing in shaft direct-reduction processes. This document is applicable to lump ores and hot-bonded pellets.
英文名称Iron ores for shaft direct-reduction feedstocks — Determination of the low-temperature reduction-disintegration index and degree of metallization
