  • Publication number: 20220325368
    Abstract: There is provided a method of dynamic control for a bottom blowing O2—CO2—CaO converter steelmaking process. In the process, O2 is adopted as a top blowing gas, a mixed gas O2+CO2 is adopted as a bottom blowing carrier gas to inject lime powders into the converter from a bottom blowing tuyere. The ingredients of the molten steel in the converter steelmaking process are predicted based on the conservation of matter, in combination with the ingredient data of charged molten iron, the ingredient data of the converter gas in the converter blowing process, and working conditions of the bottom blowing device. The top blowing oxygen amount, the bottom blowing gas ratio and the flow rate of lime powder are dynamically adjusted stage by stage according to requirements for target ingredients at the end point of blowing.
