  • Patent number: 5766543
    Abstract: A flow control device for the outlet of a molten metal handling vessel is provided for use towards the end of the pouring of molten metal through the outlet. The flow control device has a head portion and a tail portion with flow channels defined between the head and tail portions to reduce vortex effects in the molten metal, the tail portion being contoured to fit into a correspondingly contoured entrance to the outlet with the flow channels leading into the outlet and the device being attached to a refractory positioning device so that it can be fitted into the outlet during flow of the molten metal through the outlet. The head includes a baffle plate covering the outlet.

  • Patent number: 5718415
    Abstract: A flow control device for the outlet nozzle for a molten metal handling vessel, such as a ladle, includes a plug that fits in the outlet nozzle to define a gap between the plug and a closure for the nozzle. The plug has a plurality of apertures which are closed by steel plates, or other material, that melts under the influence of the molten metal in the vessel. When molten metal is placed into the vessel and the closure for the outlet is opened, the molten metal flows into the apertures, melting the meltable material in the apertures, and out the outlet. Using a device and method described allows the amount of molten metal in a ladle to be reduced to about 0.5%, and a greater than 99% free opening rate can be provided.
