Physical Simulation and Industrial Testing of Bottom-Blown $ O_{2} $-CaO Converter for Steelmaking Process
Abstract Bottom-blowing $ O_{2} $-CaO steelmaking technology has numerous advantages such as low iron and steel consumptions, low dust emissions, and molten steel cleanliness. Responsive to a weak stirring and high iron oxide slag in a 120-ton conventional “combined blowing” converter in a factory,...

| 520 | |a Abstract Bottom-blowing $ O_{2} $-CaO steelmaking technology has numerous advantages such as low iron and steel consumptions, low dust emissions, and molten steel cleanliness. Responsive to a weak stirring and high iron oxide slag in a 120-ton conventional “combined blowing” converter in a factory, a cold model of bottom-blowing $ O_{2} $-CaO was designed. Bottom-blowing and top-blowing parameters on the mixing effect of bottom-blowing $ O_{2} $-CaO converter were studied. Two symmetrical points on 0.4R trunnion connection of the bottom-blowing converter were sought as the optimum hole location. The total flow rate of bottom–blowing and top-blowing was 8.2 and 75 $ Nm^{3} $/h, respectively. The optimum top-blowing position was 400 mm and the optimum solid–gas ratio was found to be 9.0. The optimum scheme under laboratory conditions was converted and applied to a 120-ton bottom-blown $ O_{2} $-CaO converter; subsequently, hundred industrial tests were performed. The stirring strength of the molten bath was enhanced remarkably and the metallurgical effect was improved remarkably. Carbon and oxygen product of the end-point molten steel was reduced by 5.87 × $ 10^{−4} $ while the iron oxide content in the final slag was reduced by 1.99 pct. This laid a foundation for industrial applications of the bottom-blown $ O_{2} $-CaO converter steelmaking technology. | ||

Physical Simulation and Industrial Testing of Bottom-Blown $ O_{2} $-CaO Converter for Steelmaking Process |
| abstract |
Abstract Bottom-blowing $ O_{2} $-CaO steelmaking technology has numerous advantages such as low iron and steel consumptions, low dust emissions, and molten steel cleanliness. Responsive to a weak stirring and high iron oxide slag in a 120-ton conventional “combined blowing” converter in a factory, a cold model of bottom-blowing $ O_{2} $-CaO was designed. Bottom-blowing and top-blowing parameters on the mixing effect of bottom-blowing $ O_{2} $-CaO converter were studied. Two symmetrical points on 0.4R trunnion connection of the bottom-blowing converter were sought as the optimum hole location. The total flow rate of bottom–blowing and top-blowing was 8.2 and 75 $ Nm^{3} $/h, respectively. The optimum top-blowing position was 400 mm and the optimum solid–gas ratio was found to be 9.0. The optimum scheme under laboratory conditions was converted and applied to a 120-ton bottom-blown $ O_{2} $-CaO converter; subsequently, hundred industrial tests were performed. The stirring strength of the molten bath was enhanced remarkably and the metallurgical effect was improved remarkably. Carbon and oxygen product of the end-point molten steel was reduced by 5.87 × $ 10^{−4} $ while the iron oxide content in the final slag was reduced by 1.99 pct. This laid a foundation for industrial applications of the bottom-blown $ O_{2} $-CaO converter steelmaking technology. © The Minerals, Metals & Materials Society and ASM International 2020 |
