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.
