标准摘要
[中文适用范围]： ISO 4696 的这一部分规定了一种方法，用于评估铁矿石在类似于低温还原区普遍存在的条件下用一氧化碳、二氧化碳、氢气和氮气还原时的尺寸退化程度。 高炉。 ISO 4696 的这一部分适用于块矿、烧结矿和热粘合球团矿。 [外文原描述]： ISO 4696-1:2015 specifies a method to provide a relative measure for evaluating the degree of size degradation of iron ores when reduced with carbon monoxide, carbon dioxide, hydrogen, and nitrogen, under conditions resembling those prevailing in the low-temperature reduction zone of a blast furnace. ISO 4696-1:2015 is applicable to lump ores, sinters, and hot-bonded pellets.
英文名称Iron ores for blast furnace feedstocks — Determination of low-temperature reduction-disintegration indices by static method — Part 1: Reduction with CO, CO2, H2 and N2
