Ladle nozzles are classified based on their design, functionality, and material composition.
The main types include:
1. Fixed Ladle Nozzle
A simple, non-adjustable nozzle.
Provides continuous and steady flow.
Used when a constant flow rate is acceptable.
2. Slide Gate Nozzle
Includes a sliding gate mechanism to control the molten metal flow.
Allows on/off control and adjustable flow rates.
Commonly used in continuous casting.
3. Stopper Rod Nozzle
Works with a stopper rod that moves up and down to regulate flow.
Commonly used in tundishes and ladles.
Provides better control over flow rate.
4. Monoblock Nozzle
A single-piece refractory nozzle that offers high resistance to thermal shock and erosion.
Helps in maintaining metal purity and reducing clogging.
5. Composite Nozzle
Made of multiple refractory materials for better performance.
Inner lining is highly resistant to erosion and corrosion.
Outer structure provides strength and durability.
6. Argon Purging Nozzle (Gas-Injection Nozzle)
Designed to inject argon gas to prevent nozzle clogging.
Helps in improving steel cleanliness and maintaining smooth flow.
Used in high-quality steel production.
