摘要：

A study has been made of carbon dissolution from industrial cokes and specially treated cokes in hot metal. With these results together with earlier investigations, a model is presented which explains carbon pick-up from coke by hot metal. Factors relating to hot metal, coke and experimental conditions are included. 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 composition. The results on the special cokes indicate that the presence of iron oxide is favourable for carburization. Some additives, i.e., CaO, MgO, SiO2 and Al2O3 reduce the dissolution of carbon.
