Tilting tundish

Claim 3

A method for dispensing a substantially constant flow of liquid according to claim 1, wherein: said pulsating flow of liquid is fed into said container at a rate such that said container does not rotate through an angle of more than 10° about said axis.

Claim 4

A method for dispensing a substantially constant flow of liquid according to claim 2, wherein: said liquid is molten metal and is dispensed at low velocity and cast into strip form.

Claim 5

Apparatus for transforming a pulsating flow of liquid and dispensing a constant flow of liquid, comprising: a. A rotatable container for holding and regulating flow of a liquid, having closed sides, a bottom, an opening for receiving a pulsating flow of liquid, and an opening for dispensing liquid, said container being rotatably supported by a bearing surface having a horizontal axis being generally vertically coplanar with said receiving and dispensing openings, said container adapted to hold variable amounts of said liquid and extending laterally beyond said horizontal axis so as to create a torque force about said horizontal axis when holding a given level of liquid and thereby to cause said container to rotate about said horizontal axis; and b. countertorque means comprising a counterweight connected to said rotatable container for applying a torque force to said container that balances the torque force created by said container and its contained liquid and causes the liquid depth above said dispensing opening to remain essentially constant despite rotation of said container about said horizontal axis and variations in the volume of the liquid whereby said liquid may be dispensed from said dispensing opening at a substantially constant flow.

Claim 6

Apparatus for transforming a pulsating flow of liquid and dispensing a constant flow of liquid, comprising: a. A rotatable container for holding and regulating flow of a liquid, having closed sides, a bottom, an opening for receiving a pulsating flow of liquid, and an opening for dispensing liquid, said container being rotatably supported by a bearing surface having a horizontal axis being generally vertically coplanar with said receiving and dispensing openings, said container adapted to hold variable amounts of said liquid and extending laterally beyond said horizontal axis so as to create a torque force about said horizontal axis when holding a given level of liquid and thereby to cause said container to rotate about said horizontal axis; and b. countertorque means comprising a counterweight connected to said rotatable container for applying a torque force to said container that balances the torque force created by said container and its contained liquid and causes the liquid depth above said dispensing opening to remain essentially constant despite rotation of said container about said horizontal axis and variations in the volume of the liquid whereby said liquid may be dispensed from said dispensing opening at a substantially constant flow.

Claim 7

Apparatus for transforming a pulsating flow of liquid and dispensing a substantially constant flow of liquid according to claim 1, wherein: said countertorque means comprise a fixed weight attached to said rotatable container.

Claim 8

Apparatus for transforming a pulsating flow of liquid and dispensing a substantially constant flow of liquid according to claim 1, wherein: said rotatable container comprises a first chamber containing said receiving and dispensing openings; said first chamber being open to a second chamber which extends laterally beyond the horizontal axis of the bearing surface and is adapted to hold a variable quantity of liquid.

Claim 9

A tundish for transforming a pulsating flow of molten metal and dispensing a constant flow of molten metal operatively associated with means for feeding molten metal into a receiving opening of said tundish and means for receiving and casting molten metal upon its exit from a dispensing opening of the tundish said tundish comprising: d. rotatable tundish for holding and regulating flow of molten metal having closed sides, a bottom, an opening for receiving a pulsating flow of molten metal, and an opening for dispensing molten metal, said tundish being rotatably supported by a bearing surface having a horizontal axis being generally vertically coplanar with said receiving and dispensing openings, and tundish adapted to hold variable amounts of said molten metal and extending laterally beyond said horizontal axis so as to create a torque force about said horizontal axis when holding a given depth of molten metal and thereby to cause said tundish to rotate about said horizontal axis; and b. countertorque means comprising a counterweight connected to said rotatable tundish for applying a torque force to said tundish that balances the torque force created by said tundish and its contained molten metal and causes the molten metal depth above said dispensing opening to remain substantially constant despite the rotation of said tundish about said horizontal axis and variations in the volume of the molten metal whereby said molten metal may be dispensed from said dispensing opening at a substantially constant flow.

Claim 10

A tundish for transforming a pulsating flow of molten metal and dispensing a constant flow of molten metal operatively associated with means for feeding molten metal into a receiving opening of said tundish and means for receiving and casting molten metal upon its exit from a dispensing opening of the tundish said tundish comprising: d. rotatable tundish for holding and regulating flow of molten metal having closed sides, a bottom, an opening for receiving a pulsating flow of molten metal, and an opening for dispensing molten metal, said tundish being rotatably supported by a bearing surface having a horizontal axis being generally vertically coplanar with said receiving and dispensing openings, and tundish adapted to hold variable amounts of said molten metal and extending laterally beyond said horizontal axis so as to create a torque force about said horizontal axis when holding a given depth of molten metal and thereby to cause said tundish to rotate about said horizontal axis; and b. countertorque means comprising a counterweight connected to said rotatable tundish for applying a torque force to said tundish that balances the torque force created by said tundish and its contained molten metal and causes the molten metal depth above said dispensing opening to remain substantially constant despite the rotation of said tundish about said horizontal axis and variations in the volume of the molten metal whereby said molten metal may be dispensed from said dispensing opening at a substantially constant flow.

Claim 11

A tundish for transforming a pulsating flow of molten metal and dispensing a constant flow of molten metal operatively associated with means for feeding molten metal into a receiving opening of said tundish and means for receiving and casting molten metal upon its exit from a dispensing opening of the tundish according to claim 7, wherein: said countertorque means comprise a fixed weight attached to said rotatable tundish.

Claim 12

A tundish for transforming a pulsating flow of molten metal and dispensing a constant flow of molten metal operatively associated with means for feeding molten metal into a receiving opening of said tundish and means for receiving and casting molten metal upon its exit from a dispensing opening of the tundish, according to claim 7, wherein: said rotatable tundish comprises a first chamber containing said receiving and dispensing openings; said first chamber being open to a second chamber which extends laterally beyond the horizontal axis of the bearing surface and is adapted to hold a variable quantity of molten metal.
