![]() When the coke particle size was between 0.5-2.5 mm, the gasification dephosphorization rate changed little, about 58%, but when the coke particle size between 2.5-3.5 mm, the gasification dephosphorization rate dropped to 52%. When the amount of the added coke powder is sufficient, increasing mass percent of FeO of slag properly was favorable for the gasification dephosphorization reaction. The gasification dephosphorization rate decreased with the increasing of the slag basicity. The results showed that with the increasing of the experimental temperature, the gasification dephosphorization rate of coke powder gradually increaseed, and the gasification dephosphorization rate at 1 900 K could reach up to 82.35%. Abstract In order to realize the gasification dephosphorization process in converter slag splashing stage which is beneficial to avoid the P enrichment and achieve the recycling of the dephosphorized slag in subsequent furnaces, the experiment of reduction of converter slag by coke powder in the laboratory was carried out. ![]()
