标准范围

ISO 11258:2007规定了一种方法，该方法提供了一种相对测量方法，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。它规定了还原度、最终还原度和金属化度的测定。ISO 11258:2007适用于块状矿石和热粘结球团。

ISO 11258:2007 specifies a method to provide a relative measure for evaluating the extent 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 reducibilty, final degree of reduction and degree of metallization.ISO 11258:2007 is applicable to lump ores and hot-bonded pellets.
