The Development of an Eulerian Deposition Model in Liquid Metal Flows and Its Application on Nozzle Clogging during Continuous Casting of Steel
An Eulerian deposition model was developed and used to predict the deposition rates of non-metallic inclusions in liquidmetal flows.Effects of parameters such as particle diameter,wall roughness and temperature gradient near the wall on the deposition rates were investigated.Thereafter,the modified Eulerian model was used to calculate the deposition rate of non-metallic inclusions in a tundish nozzle.Furthermore,the deposition rates of different-size inclusions in the SEN were predicted and compared.The results show that both the wall roughness and thermophoresis have a significant influence on the deposition rate of small particles.For larger inclusions,turbophoresis is the main deposition mechanism.In addition,an uneven distribution of the inclusion deposition rates at the inner wall of the SEN was observed.A large deposition rate was found at the regions near the SEN inlet,the SEN bottom and the upper region of two SEN ports.
