Abstract
According to a first embodiment, a molten metal transferring system is provided. The system includes a device capable of lifting molten metal from a bath to a launder at varying quantity per unit of time. The system includes a sensor, such as a laser, arranged to monitor molten metal flow in the launder. The launder further includes a removeable insert facilitating, reversible modification of a cross-sectional area of the launder.
Claims13
A process for transporting molten metal from a furnace to at least two different vessels, comprising:
- providing a heating chamber configured to contain and heat a supply of the molten metal;
- providing a variable speed pump, the pump having a pump inlet in fluid communication with the heating chamber and a pump outlet in fluid communication with a launder, said launder including a removable insert for adjusting a cross-sectional area of the launder;
- a molten metal level sensor located in association with the launder and connected to the pump or a controller of the pump for providing a pump speed control signal, the level sensor configured to monitor a level of the molten metal in the launder upstream of the insert when present,
- wherein in either order (i) molten metal is transported through the launder to a relatively larger of the vessels without the insert present and (ii) molten metal is transported through the launder to a relatively smaller of the vessels with the insert present.
