APPARATUS FOR CONTROLLING MOLTEN METAL FLOW IN A TUNDISH TO ENHANCE INCLUSION FLOAT OUT FROM A MOLTEN METAL BATH

摘要

Flow control apparatus for enhancing inclusion float out in a continuous cas ter tundish comprising a dam positioned downstream from an impact pad and an energy sour ce positioned between the dam and the exit nozzle of the tundish. The dam receives an inco ming flood of molten metal released from the impact pad and redirects the flood of molten metal i nto multiple sub-flow currents which carry entrained inclusions toward a slag cover on the surface of the molten metal bath to enhance inclusion float out. The energy source provides means to restore kinetic energy to the sub- flow currents and increase the number of passes below the slag cover, thereb y further enhancing inclusion float out.
