ISO 11258:2015规定了一种方法,以提供一种相对测量方法,用于评估在类似于竖井直接还原工艺的条件下还原时,从铁矿石中去除氧气的程度和难易程度。它规定了还原性、最终还原度和金属化程度的测定。
ISO 11258:2015适用于块状矿石和热粘结球团。
ISO 11258:2015 specifies a method to provide a relative measure for evaluating the extent to and ease to which oxygen can be removed from iron ores, when reduced under conditions resembling those prevailing in shaft direct-reduction processes. It specifies the determination of the reducibility, final degree of reduction, and degree of metallization.
ISO 11258:2015 is applicable to lump ores and hot-bonded pellets.
