  • According to the practical conditions of 65 t ladle,the effects of bottom blowing design and process parameters on slag entrapping,turbulent kinetic energy and lining Erosion of the ladle has been investigated by Fluent s of tware.Under the condition of 100 L/min bottom blowing,slag entrapping will not readily occur because the steel flow velocity on steel-slag interface ranges from 0.15~0.2 m/s,which is less than critical velocity 0.229 m/s at which slag entrapping can happen.The distribution of turbulent kinetic energy is reasonable when the intersection angle and the center distance of bottom blowing were 180° and 0.6R,respectively.Under this constructional condition,the predicted mixing time by Fluent soft-ware is good agreement with that of the cold model experiment.The standard error is within 5%,showing the good reliability of the numerical simulation.
