In the present paper, a study has been made of carbon dissolution from industrial cokes and specially treated cokes in hot metal. With these results obtained together with earlier investigations, a model is now presented, which attempts to explain carbon pick‐up from coke by hot metal. Factors relating to hot metal, coke and experimental conditions are included in the model. An attempt is also made to quantify carbon dissolution behaviour from coke in hot metal in comparison with that of pure graphite. It was determined, that the carburizing ability of cokes can be modified by controlling the ash compositon. The results of the special cokes indicate clearly that the presence of iron oxide is favourable for carburization. Some additives, i.e. CaO, MgO, SiO 2 and Al 2 O 3 reduce significantly the dissolution of carbon.
