Iron ores for shaft direct-reduction feedstocks — Determination of the low-temperature reduction-disintegration index and degree of metallization
竖井直接还原原料用铁矿石.低温还原分解指数和金属化程度的测定
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.
