Numerical Simulation of the Slag Splashing Process in A 120 Ton Top-Blown Converter

Slag splashing operations at the end of converter blow process can improve furnace liner life and operation rate. However, effect factors on slag actual dimensions is yet to be fully understood. A three-dimensional transient mathematical model coupled with response surface analysis has been established investigate effects amount remaining slag, oxygen lance height, top-blowing nitrogen flowrate in a 120 ton top-blown converter. The predicted density validated by experimental data. numerical simulation results show that area ratio increase which greatest splashing. As height decreases, first then decrease. positively correlated ratio. When high, impact not significant. increases increasing as low.
