Proven Flow Control Technology for Steel Continuous Casting Operations

Tundish metering nozzles represent proven, legacy technology that directly controls the volume of metal flowing from tundish to mold during continuous casting operations. Unlike complex slide gate plates, these straightforward components provide reliable, consistent flow control for billet and rebar production with predictable performance characteristics.

Zircoa offers multiple bore styles and assemblies engineered specifically for continuous casting of non-aggressive and low-carbon steels. Whether you need 8-hour basic performance or extended 24+ hour casting sequences, we match our technical and development resources to meet the caster’s constantly changing needs.

Tundish Metering Nozzle Selection and Performance

Composition Options for Different Casting Requirements

Composition 3004 for Non-aggressive Steels, Average Casting Times — Coarse grain metering nozzle mix developed to optimize thermal shock resistance while providing good erosion resistance. Typically provides 8-12 hours of casting time.

Composition 3077 for Low Carbon Steels, Moderate Casting Times — Developed for operations where 24-hour sequence casting isn’t practical, but 14-20 hour times are desirable. Superior erosion resistance compared to 3004, even when casting low-carbon steels.

Composition 2134 for Low Carbon Steels, Extended Casting Times — Two-part design featuring a fine grain, low porosity inner metering nozzle within a coarse grain support block. Optimizes erosion resistance and maximizes casting times with extremely uniform stream flow and casting times exceeding 24 hours.
