L/D Top Nozzle |
- · A nozzle for continuous supply of molten steel from L/D bottom to sliding nozzle plate.
- · Placed at the top of the upper plate, which is why it is named a top nozzle.
- · The top nozzle can be replaced several times in accordance with L/D repair lifespan.

L/D Sliding Nozzle Plate |
- · Plate-shaped refractories (2 or 3 pieces) are used to control the molten steel flow into L/D~T/D.
- · Sliding nozzle plate is fitted in an operating unit called a cassette and controls the flow by sliding and thus changing pore size areas.
- · 2- and 3-piece types are used for continuous casting and pouring pit, respectively.

L/D Collector Nozzle |
- · A nozzle connecting the sliding nozzle plate’s lower plate with the shroud nozzle.
- · Named a collector nozzle as it collects L/D’s molten steel and connects it to T/D.
- · A collector nozzle is used once or as long as the plate lifespan.
|
| 4 |
T/D Porous Nozzle |
- · A nozzle continuously providing molten steel from T/D bottom to sliding nozzle plate.
- · Developed as a porous nozzle for Ar injection to prevent any inclusion blockage.
|
| 5 |
T/D Sliding Nozzle Plate |
- · 3-piece plate-shaped refractories control the molten steel flow into T/D~Mold.
- · Fitted in an operation unit called a cassette, the sliding nozzle plate controls the flow while sliding and thus changing the pore size area.
- · Ar is injected into the upper or middle plate to prevent molten steel from clogging.
