Abstract:With the thinner of the automobile panel, the press crack defects caused by the large‐size calcium aluminate inclusions at the automakers become obvious. Herein, in order to stabilize the control of calcium aluminate inclusions in the molten steel, the vortex slag entrainment (VSE) of a 300 ton ladle is investigated by the numerical simulation. The effects of the steel throughput, cofferdam height close to the nozzle, and ladle bottom structure on the VSE are analyzed. Results demonstrate that the residual mol… Show more
