Casting Processes| Резюме: | The results of analysis of process decarburization of Fe–C melts in oxidative conditions are presented. The values of the activation energy of the decarburization of Fe−C melts obtained experimentally of the order E=10 kJ/mol (2,3 kcal /mol) are smaller than apparent activation energy of chemical processes. The results of kinetic possibilities of removal of carbon from Fe–C melts in external diffusion regime of the reaction shows that process of carbon oxidation in melts based on Fe−C at |C|>|C|K in the temperature range from 1720 to 2110 K are limitated by diffusion of oxidizer – oxygen in the gas phase. |
