摘要：
In this study, direct-reduced iron (DRI) pellets with different carbon contents were produced by gaseous reduction and carburizing. The DRI pellets were then injected to a laboratory slag-steel melt. During injection, infrared radiation gas analysis was used to monitor CO content in the offgas. It was found that carbon transfer to the steel melt can be achieved despite the presence of an oxidizing slag, and DRI injection might be an effective approach to reducing the nitrogen content of EAF steel.
