Numerical Simulation of Melting Kinetics of Metal Particles during Tapping with Argon-Bottom Stirring

Abstract: Molten steel is alloyed during tapping from the melting furnace to the argon-bottom stirred ladle. The metallic additions thrown to the ladle during the ladle filling time are at room temperature. The melting rates or kinetics of sinking-metals, like nickel, are simulated through a multiphase Euler–Lagrangian mathematical model during this operation. The melting rate of a metallic particle depends on its trajectory within regions of the melt with high or low turbulence levels, delaying or speeding up their mel… Show more

“…[37,38] The higher the turbulent intensity, the higher the melting rate of particles. [31,40] Though the effect of gas flow rate, number and configuration of bottom tuyeres on mixing phenomena has been investigated, and the uniform conclusions could hardly be obtained yet. Hence, a numerical model was developed to obtain the optimal bottom tuyere configurations and gas flow rate scheme for a specific GOR furnace.…”
