Product Introduction
Shandong Luming New Materials Technology Co., Ltd. specializes in premium Zirconium Ramming Mass, a high-performance refractory material engineered for extreme temperature environments. With ZrO₂ content up to 65%, our ramming mass delivers exceptional corrosion resistance (up to 1750℃), outstanding thermal shock stability, and prolonged service life. Ideal for glass furnaces, non-ferrous metal smelting, and petrochemical applications.
Key Features
1. Superior Corrosion Resistance: High zirconia content effectively resists erosion from molten glass and metal slags.
2. Excellent Thermal Stability: Maintains structural integrity under rapid temperature fluctuations (1100℃ water cooling cycles ≥20 times).
3. High Density & Strength: Bulk density ≥3.5g/cm³ with compressive strength ≥80MPa ensures durability.
4. Easy Installation: Plastic consistency allows for seamless manual or mechanical ramming.
5. Low Contamination: Minimal Fe₂O₃ content (<0.3%) prevents product contamination in glass production.
