Product Description

Product Description

Tundish Metering Nozzle is engineered with a high-density refractory body and a premium Zirconia (ZrO2) insert, designed for precise flow control in steel continuous casting. The zirconia insert provides exceptional erosion resistance at the critical bore section, ensuring stable casting speed and extended sequence life. Each nozzle is manufactured with strict dimensional tolerance to guarantee a perfect fit with existing tundish seating blocks.

Features

Premium Zirconia Insert: ZrO2 content up to 95% at the bore for superior erosion and corrosion resistance.
Precise Flow Control: Tight bore tolerance ensures stable and consistent steel flow during casting.
High Refractoriness: Withstands extreme temperatures from 1580°C to 2000°C.
Extended Sequence Life: Designed for multiple heats (casting sequences), reducing tundish change frequency.
Excellent Spalling Resistance: High thermal shock resistance for rapid start-up and stable operation.
Customizable Dimensions: Bore size and overall dimensions fully customizable to your ladle/tundish system.

Applications

Continuous Casting: Steel billets, blooms, and slabs production lines.
Ladle & Tundish Systems: Flow metering and control between ladle and tundish.
Specialty Steel Plants: Carbon steel, alloy steel, and stainless steel casting.
High-Throughput Mills: Applications requiring extended casting sequences and minimal downtime.
