In response to the limitations and optimization needs of the existing process parameters, this study proposes a new optimization scheme for the bottom blowing of argon in the ladle, and combines experimental verification to demonstrate its good effect in improving the quality of steel and reducing ingot defects.The scheme uses the PIMS (Process Integrated Modeling System) software to optimize the flow rate, pressure, and position of the argon blowing, in order to effectively capture and remove impurities such as non-metallic inclusions and oxides in the steel. By simulating the coverage range of argon gas in the molten iron, the optimal flow position and speed of the gas are determined, and a parameter adjustment plan is formulated. The experimental results show that after adopting the new scheme, the content of non-metallic inclusions in the steel is reduced by 25%, the content of oxides is reduced by 19%, and the defect rate of the ingot is significantly reduced.Through conducting fundamental experiments and simulation research, this study has built a feasible optimization scheme for the bottom blowing of argon in the ladle, which has high practicality and universality, and has made a certain contribution to improving the quality and efficiency of the steel industry.【Keywords】 Bottom blowing of argon; Experimental research; Optimization scheme; Quality control.
