Water Model Study on Removing Inclusion from Molten Steel by Bubble Attachment in RH Degasser

Abstract: In this paper, a water model is established, at geometric similarity ratio of 1:4, to simulate a real 180-t RH vacuum refining device. Removing inclusion from molten steel by bubble attachment in RH degasser is analyzed using the water model. The effects of variables such as bubble size, treatment time,life-gas flow rate, amount and time of NaHCO3 addition are investigated by using high speed video and image-process software.
