Introduction

Silica bricks have become the preferred choice for hot blast furnaces, gradually replacing traditional clay and high-alumina bricks. These high-purity bricks are engineered for optimal performance under extreme conditions, making them essential in modern industrial applications.

Key Features

• High Purity: SiO2 content of 95% or more for stable high-temperature performance.
• Excellent Thermal Conductivity: Supports efficient operation of hot blast furnaces.
• High-Temperature Resistance: Cold compressive strength of ≥45MPa to withstand harsh working environments.
• Low Thermal Expansion: Thermal expansion rate at 1000℃ ≤1.25%, ensuring structural stability.
• High Softening Point: Softening point at 0.2MPa ≥1650℃ suitable for high-temperature applications.
• Low Creep Rate: Reliable for long-term use with a creep rate of just 0.8% (0.2MPa×50h).

Applications

These silica bricks are ideally suited for:

• High-temperature zones in hot blast furnaces.
• Other industrial furnace equipment subjected to high temperature and pressure.
