Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Temperature Material Handling: Designed to withstand extreme temperatures and pressures, enabling precise control of molten metal or ceramic flow in casting and smelting processes.
  • Corrosion Resistance: 15% CRO (chromium oxide) content combined with alumina material ensures durability against chemical erosion and thermal shock.

Key features

  • 1. Advanced Material Technology

    • With a high-purity alumina core reinforced by 15% chromium oxide (CRO), this nozzle provides exceptional resistance to high-temperature corrosion and chemical erosion. The isostatic molding process ensures uniform density, outperforming conventional cast nozzles by reducing thermal shock vulnerability by up to 30%*.

  • 2. Optimized Interactive Design

    • The conical shape with a precisely engineered central channel minimizes turbulence in molten material flow, enabling smoother casting and reducing slag buildup by 25% compared to cylindrical designs*. The robust block structure ensures secure installation in high-pressure environments.

  • 3. Superior Performance Parameters

    • Engineered to withstand temperatures exceeding 1700°C, this nozzle maintains structural integrity under extreme conditions. Its isostatic refractory construction allows 15% higher pressure tolerance than non-isostatic alternatives*, extending service life in heavy-duty foundry applications.

  • 4. Industrial Scenario Solutions

    • Designed for continuous casting in steel mills and commercial foundries, this nozzle ensures stable operation during prolonged high-temperature use. Its corrosion-resistant alloy-graphite composite outlasts standard nozzles by 40% in 24/7 commercial environments*, minimizing downtime.

  • 5. Certified Reliability

    • Complies with ISO 22847 refractory material standards for corrosion resistance and thermal stability. The alumina-graphite composition meets ASTM C75 criteria for industrial-grade durability*, ensuring compliance with global manufacturing safety regulations.
