基于模拟高炉环境下焦炭热强度的配煤研究

Study on coal blending for hot strength of coke based on blast furnace simulation

通过模拟高炉反应条件,介绍了评价焦炭质量优劣的方法,并提出了焦炭在模拟高炉喷煤反应条件下的反应性(RI)和反应后强度(I10^600)。研究表明,较高的I10^600是保证高炉顺行、实现高喷煤比的重要条件。

This paper introduced a method for coke quality evaluation based on simulated PCI reaction condition of blast furnace.It also gave reactivity index(RI)and coke strength after reaction(I10^600).The result shows that the I10^600 plays an important role in ensuring smooth operation and realizing high injection ratio for the blast furnace.
