摘要:

通过与沙钢7.63m焦炉焦炭质量对比,系统地分析了俄罗斯OAO NLMK钢铁公司配入DK型添加剂生产的焦炭性质。研究表明,OAO NLMK钢铁公司焦炭质量低于沙钢焦炭,微观组织中破片组织含量多,灰成分碱金属含量高,基质的反应性高,石墨化程度高。

Abstract:

With comparison of the coke produced from the 7.63m coke oven battery of Shasteel,the properties of the coke produced with addition of DK additive in OAO NLMK Iron & Steel Company in Russia is studied.The result shows that the quality of coke produced in OAO NLMK is not as good as that produced in Shasteel.There are more fragment structures in the microstructure.Alkali metal content in ash is higher.CRI of coke and graphite degree are higher.
