Product Overview
The cast zirconia refractory brick (zirconia mullite refractory
brick) is a high-performance refractory material specifically
designed for high-temperature environments in the steel industry.
It is primarily used in critical parts such as slide rails and
pusher systems. By incorporating ZrO₂ into the Al₂O₃-SiO₂ system,
the product significantly enhances the chemical resistance, wear
resistance, and thermal stability of mullite.
Main Features
1. High Wear Resistance
Manufactured using the casting process, the brick has a dense
crystalline structure, offering superior wear resistance. Its
service life is more than double that of traditional materials.
2. High-Temperature Stability
With a high load-softening temperature and excellent thermal
stability, the brick maintains its structural integrity in extreme
high-temperature conditions.
3. Chemical Resistance
It exhibits good resistance to acidic or neutral slag and remains
stable in oxidizing atmospheres.
4. Thermal Shock Resistance
It can effectively withstand thermal stress from rapid heating and
cooling, reducing the risk of cracking.
5. Low Thermal Expansion Coefficient
The brick has a low thermal expansion rate, making it suitable for
slide rail systems with frequent temperature changes.
