Abstract：According to coal blending scheme of Tanggang, taking the representative coke as the research object, the influence of ash composition and optical texture on coke thermal property was investigated. The results showed that coke ash composition have a large effect on mineral catalytic index. With the increase of the MCI, the reactivity of coke had a trend to rise, but the post-reaction strength decreased. Coke optical texture had a close relation to anisotropy index. With increasing the OTI, the reactivity of coke had a trend to decrease, but the post-reaction strength rised. The coke ash composition and optical organization were reasonably controlled, which is conducive to perfecting the coke reactivity and post-reaction strength in BF.
