APPARATUS FOR CONTROLLING MOLTEN METAL FLOW IN A TUNDISH.

摘要

Flow control apparatus for enhancing inclusion float out in a continuous caster tundish comprising a dam (3) positioned downstream from an impact pad (5) and an energy source (4) positioned between the dam (3) and the exit nozzle (2) of the tundish. The dam (3) receives an incoming flood of molten metal released from the impact pad (5) and redirects the flood of molten metal into 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 (4) provides means to restore kinetic energy to the sub-flow currents and increase the number of passes below the slag cover, thereby further enhancing inclusion float out.
