AbstractA numerical simulation was used in describing the interfacial behavior between molten steel and liquid slag layer with different flow-control technologies in the slab continuous casting mold, in which the effects of argon gas flow rate, casting speed and current intensity of coils on the interfacial behavior of molten steel and liquid slag with the coupling action of electromagnetic brake (EMBr) and argon gas injection were considered. The relationship between the level fluctuation index of F value and level fluctuation of free surface was also investigated. For a given casting speed with EMBr, increasing the argon gas flow rate can aggravate the local fluctuation of interface so much as lead to the break-Lip of the steel-slag interface, F value increases with increasing argon gas flow rate and the thickness of liquid slag near the meniscus increases linearly with F value. For a given argon gas flow rate with EMBr, increasing the casting speed has helpful for restraining the interfacial fluctuation near the nozzle, and F value also increasing, the thickness of liquid slag near the meniscus reduces linearly with F value. On the contrary, for a certain casting speed and argon gas flow rate, increasing the current intensity of coils can aggravate the steel/slag interfacial fluctuation near the nozzle.
