Abstract

Coke is the most important raw material fed into the blast furnace, in terms of its effect on blast furnace operation and hot metal quality. During production of coke, coke fines are generated, which is used in sinter plant. In steel industry wherever excess of coke fines are generated, it becomes problematic to dispose these coke fines. Coke making process has passed through various stages of development over a period of time. Various types of catalyst, non-coking coals and chemical addition have been attempted in coal blend to improve the coke quality and to reduce the cost of coke. A study has been conducted where coke fines has been used in coal blend. This paper presents the salient points of the investigation on the effect of coke fines addition on M₁₀ and M₂₅ value of coke.

混煤中惰性添加及其对焦炭质量的影响

摘要

就其对高炉操作和铁水质量的影响而言，焦炭是送入高炉的最重要原材料。在焦炭生产过程中，会产生焦粉，用于烧结厂。在钢铁工业中，只要产生过量的焦粉，处理这些焦粉就会成为问题。焦炭制造过程在一段时间内经历了不同的发展阶段。为了提高焦炭质量和降低焦炭成本，已经尝试在混煤中使用各种催化剂、非焦煤和化学添加剂。已经进行了一项研究，其中焦粉已用于混煤。本文介绍了焦炭粉添加对M ₁₀和M ₂₅影响的研究要点。 可乐的价值。
