Fluid flow behaviour in slab continuous casting tundish with different configurations of gas bubbling curtain

Abstract: Fluid flow characteristics in a two strand slab continuous casting tundish with different configurations of argon gas bubbling curtain (GBC) were investigated in physical modelling experiments. It was found from this research that the GBC with a small flow rate acted as a gas dam and could greatly improve the flow characteristics in the tundish. It increased dramatically the peak concentration time and plug flow volume, decreased greatly the dead volume, created surface directed flow and eliminated short circu… Show more

“…A cortina de gás inerte pode servir para diminuir a zona de "curto-circuito", aumentando o tempo mínimo de residência do aço no distribuidor. Zhong et al [4] e Cwudzinski [5] utilizaram diferentes configurações de dispositivos combinados com a injeção de gás inerte em seus estudos. O presente trabalho teve como objetivo estudar o efeito da substituição da barragem pela cortina de gás no escoamento do aço no distribuidor.…”

“…[9][10][11] The principle behind this device is that generating an upper flow to take inclusions toward the slag layer, and the smaller inclusions are easy to float when they were trapped by bubbles. Nevertheless, the potential hazards of pinhole bubble formed in billets may exist in the application of gas curtains.…”
