Frequently Asked Questions (FAQ)
What are the primary applications of Zircon Ramming Mix?
Zircon Ramming Mix is primarily used for both cold and hot repairs of tank bottoms, tank side wall insulation layers, and superstructures. Additionally, it is applied to tamp the safety layer at the bottom of the furnace and to heat repair secondary furnace parts.
What is the operating temperature range for these monolithic refractories?
The operating temperature varies by product. Zircon-based products (such as Zircon Ramming Mix, Castable, and Patch) operate between 100°C and 1600°C. AZS and α-β Alumina products generally operate in the temperature range of 100°C to 1500°C.
How do AZS Ramming Mix and AZS Castable differ in performance?
While both have similar ZrO₂ content (28-29%), AZS Castable has a higher density (3.0 g/cm³), larger maximum particle size (10.5 mm), and higher cold pressing strength (75 MPa) compared to AZS Ramming Mix (2.9 g/cm³, 5 mm particle size, and 50 MPa strength).
What is the ZrO₂ content in the Zircon-based refractories?
The Zircon Ramming Mix, Zircon Castable, and Zircon Patch all feature a high ZrO₂ content of 64±2%, ensuring excellent stability and performance at high temperatures.
Where are α-β Alumina Mortar and α-β Alumina Ramming Mix typically applied?
Both α-β Alumina Mortar and α-β Alumina Ramming Mix are designed for the cold and hot repair of tank bottoms, tank side wall insulation layers, and superstructures.
