Sell Metallurgical Coke

Both blast furnace coke and foundry coke are made by baking a blend of selected coking coals in certain high temperature without contact with air until almost all of the volatile matter is driven off. The resulting product, coke, consists principally of carbon, as listed in above table. By-products are crude coal tar, light oils, and ammonia, etc. Generally speaking, chemistry, size, and strength have been considered the most important properties for use in the blast furnace. Other important factors are coke reactivity and CSR (coke strength after reactivity), which deal with the amount and size of pores and walls, porosity, and density. Carbon textures and microstructure are two main factors that affect the reactivity, stability, and the coke strength after reaction. To produce high quality blast furnace coke, high quality coals must be used and properly mixed. High quality coals are those coals that, when coked together, produce the highest "stability" and CSR to support the blast furnace burden and allow maximum wind for maximum production. Chinese coke is reportedly having higher CSR in comparison with the steel manufacturer Grade 1 2 3 4 5 6 7 Ash (%max) 10.5 12 13.5 15 10.5 12 13 V.M.(%max) 1.5 1.5 1.9 2.0 1.5 1.5 1.5 F.C.(%min) 88 86.5 84 83 88 86.5 85 S.
