Frequently Asked Questions (FAQ)
Q1: What are the main applications of Zircon Ramming Mix?
A1: Zircon Ramming Mix is primarily used for the cold and hot repair of tank bottoms, tank side wall insulation layers, and superstructures. It is also utilized to tamp the safety layer at the bottom of the furnace and perform heat repairs on secondary furnace parts.
Q2: What is the maximum operating temperature for these refractories?
A2: The Zircon-based refractories (Zircon Ramming Mix, Zircon Castable, and Zircon Patch) can operate at temperatures up to 1600°C. The AZS and α-β Alumina products are designed for operating temperatures up to 1500°C.
Q3: How does the ZrO₂ content compare between Zircon and AZS products?
A3: Zircon products (Ramming Mix, Castable, and Patch) feature a high ZrO₂ content of 64±2%. In contrast, AZS products contain a ZrO₂ level of approximately 28±1% to 29±1%.
Q4: What is the typical cold pressing strength of AZS Castable?
A4: AZS Castable offers a high cold pressing strength of 75 MPa, which is higher than the 50 MPa strength of AZS Ramming Mix.
Q5: Where are α-β Alumina Mortar and α-β Alumina Ramming Mix applied?
A5: 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 superstructure components.
