高炉炼铁生产工艺中耐火材料的应用研究

耐火材料在钢铁工业和有色金属工业中得到了广泛的应用。在高炉炉身设计时,应针对不同部分的需求,选用适当的耐火材料。高炉内衬耐火材料的性能是影响高炉长寿能力和降低生产成本的重要因素。为此,本文以高炉耐火材料的使用为切入点,通过对不同组分耐火材料特性的比较分析,探讨耐火材料在高炉内衬上选用路径,为延长高炉使用寿命、降低成本、改善铁水品质提供理论依据。

Theoretical Research on the Import and Export of Iron Ore and Harmful Element Detection Method based on Microwave Digestion Inductively Coupled Plasma Mass Spectrometry Approach

In this paper, we conduct research on the import and export of iron ore and harmful element detection method based on microwave digestion inductively coupled plasma mass spectrometry approach. Our country gradually increased demand for iron ore, iron ore trade, in order to ensure that the quality of the iron ore and taste which must be tested for total iron content. At the same time it also increased the demand for iron ore, although China＇ s iron ore production has been greatly improved. Our proposed approach optimizes the traditional detection method which will be meaningful.
