The elucidation of the deadman's behavior and interaction between slag–iron–coke within blast furnace hearth are essential for realization low‐carbon safe production. In this review, macrostate deadman, interactions slag–iron–coke, carburizing behaviors, renewal mechanisms comprehensively examined. First, formation state voidage, distribution coke sizes characterized. average particle size ranges from 20 to 30 mm, deadman void fraction 30–50%. Second, as well occurrence mineral layer at interface is elucidated. ash composition content key factors affecting phase composition. Third, influence exerted by critical such physical properties carbon source, molten iron, temperature on analyzed, with also being disclosed. Finally, three future focal areas proposed: characterization intelligent monitoring permeability, analysis layers control, in‐depth carburization in iron. It anticipated that studies will enhance comprehension thereby fostering furnace's sustainable development.
