DZNS Refractory 1800

DZNS Refractory 1800 is a supercritical refractory concrete in the form of a dry packaged mixture designed for use in extremely high temperatures up to 1800 °C. The material is designed for lining the most heavily loaded and critical areas of industrial thermal units, where maximum heat resistance, strength and stability under prolonged thermal exposure are required.

Temperature stability

• Maximum operating temperature: up to 1800 °C
• Recommended operating temperature: up to 1700 °C

Scope of application

Used for:

• Lining of supercritical high-temperature furnaces;
• Areas of direct contact with flame and heat radiation;
• Metallurgical, foundry and special thermal units;
• Firing chambers with extreme operating conditions;
• Continuous thermal units;
• Special industrial installations with ultra-high temperatures.

Main advantages

• Supercritical heat resistance up to 1800 °C
• Ultra-high mechanical strength after hardening
• Exceptional resistance to prolonged thermal loads
• Minimal shrinkage even at extreme temperatures
• Stable microstructure without cracking or degradation
• Long-term operation in the most severe conditions

Technical features:

• Material type: dry concrete mix;
• Structure: dense, optimised for ultra-high temperatures;
• Binder: special ultra-high temperature mineral;
• Filler: high-purity refractory filler of a special grade;
• Heating behaviour: stable under prolonged exposure to temperatures up to 1800 °C.

Recommendations for use

1. Mix with clean water until a homogeneous, plastic mass is obtained;
2. Apply only to a thoroughly prepared and cleaned substrate;
3. Avoid rapid drying after application;
4. Perform the first heating in stages and in a controlled manner, with a slow increase in temperature.

Packaging

• Bag – 25 kg
• BigBag – 1000 kg (with polypropylene liner for moisture protection)
