BS ISO 11258:2015规定了为评估范围提供相对测量的方法 当在类似的条件下还原时，可从铁矿石中去除氧气 轴直接减速过程中普遍采用的方法。它规定了可还原性的测定， 最终还原度和金属化程度。本国际标准适用于块状矿石和热粘结球团。交叉引用:ISO 2597-1ISO 2597-2ISO 3082ISO 5416ISO 9035ISO 11323ISO 9686购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS 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.This International Standard is applicable to lump ores and hot-bonded pellets.Cross References:ISO 2597-1ISO 2597-2ISO 3082ISO 5416ISO 9035ISO 11323ISO 9686All current amendments available at time of purchase are included with the purchase of this document.
