标准范围

本文件规定了一种提供相对测量的方法，用于评估当在类似于高炉还原区中普遍存在的条件下还原时从铁矿石中除去氧的程度和容易程度。本文件适用于块矿、烧结矿和热粘结球团。

This document specifies a method to provide a relative measure for evaluating the extent to and ease with which oxygen can be removed from iron ores, when reduced under conditions resembling those prevailing in the reduction zone of a blast furnace.This document is applicable to lump ores, sinters and hot-bonded pellets.
