鉴定钢中非金属夹杂物的常见方法电解分离法用电解方法使钢中夹杂物分离出来，它便于确定夹杂物的总量。金相法在金相显微镜下对受检钢样的抛光面进行观察，根据视场内夹杂物的形状、分布、色彩以及各种特征对夹杂物作出定性或半定性鉴定。电子扫描X-射线区域分析此法又叫“电子探针”，既迅速又可靠。金相法鉴定夹杂物的评定标准介绍首先可根据在光学显微镜明场下观察到的夹杂物形态、色彩和分布情况，进行粗略的定性分析，确定夹杂物是脆性的还是塑性的。

举例来说，很多大高炉炉缸断面积利用系数可达到65t/m2.d以上，而300m3小高炉要达到炉缸断面积利用系数65t/m2.d这一指标，其容积利用系数必须达到4.0t/m2.d。为了研究大型高炉生产技术，武钢从2002年起通过开展系统的基础实验研究，力图阐明大型高炉强化冶炼的限制性因素，并确定大型高炉生产的有效技术措施。武钢因受地域资源条件限制，在相当长的历史阶段内，高炉炼铁所用原燃料的质量与先进水平相比存在差距。
