Abstract
A metering gate for liquid metal flow control with reduced clogging with a top plate, having a first flow channel bore with an inlet having an inlet axis and an outlet having an outlet axis. The inlet axis and the outlet axis are offset. A throttle plate slidably mounted on the top plate selectably receives flow from the top plate. The metering gate provides a less tortuous and more symmetrical flow path when the gate is partially open, but provides a relatively straight downward flow channel allowing full flow when the gate is fully open.
Claims30
An apparatus for metering flow in the continuous casting of molten metal including a metering gate, in which the metering gate comprises:
- a top plate having a first flow channel bore with an inlet having an inlet axis and an outlet having an outlet axis where the inlet axis and the outlet axis are offset;
- and a throttle plate slidably contacting the top plate and adapted for selectably receiving flow from the top plate.
A method for metering flow in the continuous casting of molten metal comprising:
- passing fluid into a first flow channel bore in a stationary first plate of a metering gate in a first vertical direction;
- and
- passing fluid out of the first flow channel bore in the first plate in a second vertical direction horizontally offset from the first vertical direction.
An apparatus for metering flow in the continuous casting of molten metal including a metering gate, in which the metering gate comprises:
- a refractory piece comprising a top plate and a first flow channel bore with an inlet having an inlet axis and an outlet having an outlet axis where the inlet axis and the outlet axis are offset;
- and
- a throttle plate slidably contacting the top plate and adapted for selectably receiving flow from the top plate.
An apparatus for metering flow in the continuous casting of molten metal comprising:
- a first refractory piece comprising means for transporting a fluid in a first vertical direction and means for deflecting the fluid to a second vertical direction horizontally offset from the first vertical direction;
- and
- a throttle plate slidably contacting the first refractory piece and adapted for selectably receiving the flow from the first refractory piece.
