Multiphase Flow in a Steelmaking Converter Using an Unconventional Lance

Numerical simulation and application of oxygen lance in 120t BOF of PANSTEEL

“…Along with the rapid development of computer hardware and finite element analysis theory, the numerical simulation technology has been widely used in the converter smelting process. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] By model building and regression test, Lee et al 4,5 and Odenthal et al, 6 had compared the efflux characteristics of two commercial oxygen lances in steel converters and drawed a conclusion that different lances were fitted for different kinds of converter. Odenthal et al 6 used a mathematical model combining with the volume of fluid model (VOF) and discrete phase model (DPM) to describe the molten steel and slag velocity field under six nozzle supersonic jet by Fluent 6.3 software.…”

“…Wang et al 9 simulated four nozzle supersonic jet behaviour. Oxygen lance polymerisation degree was improved through the simulated of Fluent software by Ferri et al 10 The converter oxygen lance was designed on the basis of the simulated results by Sambasivam et al 11 and Barron et al 12 And the control of smoke dust of converter steelmaking and simulated supersonic oxygen jet behaviour were studied by Sumi et al 13 But systematic knowledge of characteristics of fivenozzle supersonic oxygen jet flow is still lacking, especially for the prediction of the impact depth, impact area of the cavity and the bath mixing time induced jetting of oxygen under different operational parameters in a practical steelmaking BOF.…”
