This paper describes the effect of coal pulverization on blast furnace coke making.
Coal pulverization results in a lowering of the bonding power between coal particles, but it improves the dispersed condition of coal particles with different properties. This suggests that coke strength can be increased by coal pulverization if the bonding power between coal particles is compensated for by raising bulk density.
As for formed coke making, the effect of coal pulverization on coke strength is large, because by briquetting, coal is carbonized under high bulk density. Particularly, by making coke structure fine and homogeneous, post-reaction strength is expected to improve.
Carbonization of pulverized coal under agglomerated state makes optical anisotropic texture of coke homogeneous. Coal pulverization has the possibility of changing not only the physical properties but also the chemical properties of coke.
