| Abstract: | According to the characteristics of aluminum-free deoxidization process for heavy-rail steel optimal deoxidant has been selected. By optimization of steelmaking technology, the content of O] and Al] has been under control effectively. The total oxygen and aluminum in the steel are decreased by less than 20×10^-6 and 40×10^-6 respectively, which fully satisfies the standard technical requirements of heavy-rail steel. |
