Numerical Simulation Study of the Melting of Castings in a Blast Furnace Slag Melt Pool
The melting of the material in the blast furnace slag affects the degree of metallurgical reaction.When the solid material is melted in the high temperature molten pool,the internal temperature is high,the monitoring environment is harsh,and the melting process cannot be di-rectly observed.In order to explore the melting law of the additive in the molten pool and optimize the process parameters,it used ANSYS Flu-ent software to simulate the melting behavior,and quantitatively analyzed the influence of material type and material size on the melting process of the additive.The results showed that when the particle size of the material is 0.2,0.5,1.0 and 2.0 cm,the complete melting time of the incineration slag and sludge is 0.208,1.063,3.280,8.845 and 0.146,0.755,2.950,7.520 s,respectively.During the melting process,the temperature difference between the inside and outside of the incineration slag and the sludge generally didn't exceed 30 ℃.It can provide theoretical basis and experimental support for the study of multi-industrial solid waste CO2 mineralization process based on smelting slag.
