Sizing Nozzle For Tundish 10.0MM-20.0MM
The tundish sizing nozzle is a continuous casting Refractory for steel making, which is suitable for continuous casting of steel making. The sizing nozzle of Tundish has the characteristics of long service life, corrosion resistance and good thermal shock resistance.
Products Description
Tundish sizing nozzle is a key flow-control refractory for steel continuous casting. It is installed at tundish bottom to fix molten steel flow rate and stabilize casting speed. This series covers standard bore size from 10.0mm to 20.0mm, widely used in billet and small slab continuous casting lines. Adopting high-purity zirconia composite material, it controls bore expansion and ensures stable casting operation.
Material & Structure
- Core material: High-purity stabilized zirconia (90%/93%/96% optional)
- Outer body: High alumina carbon material
- Bore size range: 10.0mm–20.0mm (custom single size available)
- Structure: Zirconia inner core + alumina outer composite structure
Product Features
- Stable flow control: Precise bore dimension keeps consistent molten steel flow, stabilizes casting speed.
- Corrosion resistance: Zirconia core resists molten steel and slag erosion, reduces bore enlargement.
- Thermal shock resistance: Adapts repeated heating and cooling, avoids cracking during continuous casting.
- Low porosity & high density: Dense structure reduces scouring loss.
- Long service life: Reduces frequent replacement and production downtime.
- Good sealing performance: Fits tundish upper nozzle assembly, no steel leakage.
