Abstract:

Mixing 40%~50% anthracite with blended coal,the formcoke reactivity index (CRI) is high while its strength after reaction (CSR) is low.After blending coal fines modifier (ZBS),thermal characteristics of formcoke were proved,which shows that ZBS modified anthracite.When mass fraction of ZBS reached 1‰,the mass of coke improved most,in which CRI decreased to 10.65% and CSR increased to 13.52%.
