Numerical Simulation of Nozzle Clogging of Ferritic Stainless Steel
According to actual circumstance of Tang Shan ferritic stainless Steel Company, making use of some scene technology parameter and referring a lot of document data, the three-dimensional mathematical model which coupled the molten steel flow with heat transfer is established by adopting the simulation software FLUENT. The result shows: The surface flow velocity and turbulent kinetic energy in liquid surface centerline is appear symmetrical around the two side in ideal condition without the nozzle clogging, but the nozzle clogging show asymmetric distribution, different place and size clogging appear different flow field and temperature. The nozzle clogging of surface temperature and mold lower temperature are higher than the sides without the nozzle clogging. Nozzle clogging is disadvantage of the removal inclusion.
