- Abstract
A three-dimensional species transport model in continuous casting mold has been developed to describe the interfacial reaction behavior and to clarify the evolution of composition and properties of the mold flux for high-Al steel. The reaction experiment and plant trial were conducted to verify the model predictions. The results show that the interfacial reaction rate is the main factor affecting the composition distribution of the mold flux. The reaction interface above the upflow zone of molten steel has a fast update rate, resulting in a rapid increase in the Al2O3 content in mold flux in this area. In addition, the mold flux near the nozzle stays in the liquid pool for a longer time to react with the molten steel, leading to the accumulation of Al2O3. The Al2O3 content in the solid film is slightly lower than that of the liquid pool due to the solidification of liquid mold flux in the early stage. The interfacial reaction increases the viscosity of the mold flux and reduces the thickness of the liquid film, thereby reducing the flux consumption.
