The thermal degradation behavior of coke in the blast furnace is investigated by experiments with rapid heating and model analysis considering the intraparticle temperature and stress distributions.
It is presumed that the thermal stress is closely related to the expansion and contraction of coke during heating and there exist two types of crack in coke in the blast furnace. One is breakage with exfoliating spherical husk and the other is split from surface to inside.
