| Abstract: | In order to improve the cleanliness of molten steel and decrease the effect to products caused by inclusions, the industrial experiments of deoxidation by Mg-alloy were carried out in quality high carbon steel which was based on the results in lab. The total oxygen, the compositions, the morphology and the size of the inclusions with different deoxidation process were investigated. The results showed that the total oxygen in molten steel deoxidizated by Mg-alloy is less than 13×10^-6 and the inclusions are small and dispersive, which indicates that the effect of deoxidation by Mg-alloy is better than Al. |
