标准范围

ISO 4698:2007规定了一种方法,用于在类似于高炉还原区普遍存在的条件下,在无约束床中还原时,评估铁矿球团体积增加的相对测量。它规定了自由膨胀指数的测定。ISO 4698:2007适用于热粘结球团。

ISO 4698:2007 specifies a method to provide a relative measure for evaluating the increase in volume of iron ore pellets, when reduced in an unconstrained bed under conditions resembling those prevailing in the reduction zone of a blast furnace. It specifies the determination of the free-swelling index.ISO 4698:2007 is applicable to hot-bonded pellets.
