  • Publication number: 20250045500
    Abstract: A method for predicting floating times of inclusions during refinements of molten steel includes: predicting a macroscopic multiphase flow field of the molten steel refining, injecting the inclusions into the multiphase flow field uniformly and randomly, determining a capture condition of the inclusions, calculating motion trajectories of the inclusions injected into the multiphase flow field, outputting captured inclusions' information through comparing the motion trajectory of the inclusion and the capture condition, and obtaining an average floating time, a relationship between a removal rate and the floating time, and the complete floating time through analyzing the captured inclusions' information.

  • Publication number: 20230325637
    Abstract: Provided is a method for determining a quantity of a calcium line fed into molten steel based on a minimum Gibbs free energy principle, which relates to an calcium treatment process of molten steel refining for iron and steel metallurgy. The method includes: establishing a connection with a database to read composition information and a temperature of the molten steel in an actual production process; calculating contents of inclusions in the molten steel according to the read composition information; calculating a required quantity of calcium of the molten steel to control the inclusions in a target area under a current condition; and calculating a length of the fed calcium line according to parameter information of the calcium treatment process and the required quantity of calcium of the molten steel. With the method, a scientific and reasonable guidance is provided for the calcium treatment process in the actual production process.
