标准摘要
[中文适用范围]： 该文件规定了一种方法，用于提供评估铁矿石球团矿体积增加的相对测量方法，当铁矿球团矿在无约束床中、在类似于高炉还原区中普遍存在的条件下还原时。 它规定了自由膨胀指数的测定。 本文件适用于热粘合颗粒。 [外文原描述]： This document specifies a method to provide a relative measure for evaluating the increase in volume of iron ore pellets, when reduced in an unconstrained bed under conditions resembling those prevailing in the reduction zone of a blast furnace. It specifies the determination of the free-swelling index. This document is applicable to hot-bonded pellets.
