标准编号：ISO 11257:2022

中文名称：直接还原炉料用铁矿石 低温还原粉化率和金属化率的测定

英文名称：Iron ores for shaft direct-reduction feedstocks — Determination of the low-temperature reduction-disintegration index and degree of metallization

发布日期：2022-03

标准范围

本文件规定了一种方法，用于在类似于竖井直接还原工艺的条件下进行还原时，评估铁矿石的粒度退化程度和金属化程度。本文件适用于块状矿石和热粘结球团。

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.
