Abstract
Molten metal fed to a rotating casting wheel is controlled by a vertical pouring spout feeding a tundish below it, a trough from the tundish to the wheel, a sensor to detect the level of metal in the trough, a pin controlled by the sensor to adjust flow through the spout, and a foraminous receptacle in the tundish to receive the flow from the spout and passivate the outflow on its way to the sensor.
Claims5
Apparatus comprising a casting wheel having a peripheral groove for receiving and solidifying molten metal, an upper chamber for receiving molten metal, a downspout from the upper chamber, a lower chamber to receive molten metal from the downspout, a trough extending laterally to convey molten metal from the lower chamber to the groove, means to regulate flow through the down spout, a sensor mounted above the trough to determine the level of molten metal in the trough, means connecting the sensor to operate the down spout flow control means, and means to prevent turbulence in the molten metal flowing through the trough beneath the sensor, said preventive means comprising a foraminous receptacle positioned in the lower chamber to receive molten metal from the down spout and cause it to pass through multiple openings through the receptacle before emerging from the receptacle.
