ժҪ Abstract: Bursting of gas bubbles on the free surface of liquid iron produces iron droplets that are ejected into the surrounding atmosphere. The influence of the freeboard pressure on gas bubble bursting was investigated by collecting and measuring the formed droplets in water and in liquid iron systems. In water modelling it was observed that gas bubbles expanded markedly during the floating up when the freeboard was evacuated but the influence of the freeboard pressure on mass of ejection is not significant when the freeboard pressure varied from 0.01 to 0.1 MPa. On the other hand, in steel melt mass of ejection increased 2-3 times when the pressure was reduced from atmospheric pressure to 66.5 Pa.
