Application of Magnesia Carbon Brick
Silica bricks thrive in high-heat industries: lining steel coke ovens, hot blast stoves, glass melting furnaces, ceramic kilns, and cement rotary kilns, enduring extreme temperatures reliably.
1. Glass Manufacturing
- Lining glass melting furnaces, silica bricks resist corrosion from molten glass (1500-1600°C), ensuring stable glass quality and reducing furnace downtime.
- Used in regenerator chambers of glass furnaces, they efficiently store and transfer heat, optimizing fuel usage in large-scale glass production.
2. Steel Industry Applications
- Used in coke ovens for iron and steel production, silica bricks line the combustion chambers, enduring 1300-1500°C to ensure consistent coke quality and extended oven lifespan.
- Applied in hot blast stoves, they withstand cyclic heating up to 1200°C, improving heat transfer efficiency and reducing energy consumption in steel mills.
3. Ceramic Industry
- Lining kilns for firing advanced ceramics, silica bricks maintain uniform temperatures up to 1600°C, critical for achieving precise ceramic material properties.
- Applied in sintering furnaces, they withstand thermal cycling, ensuring consistent results in manufacturing high-strength ceramic components.
4. Cement Production
- Used in rotary kiln burning zones, silica bricks resist high temperatures (1400-1500°C) and chemical attack from cement clinker, extending kiln service life.
- Lining preheater cyclones, they endure abrasive conditions and high heat, improving overall cement production efficiency.

Quality Assurance for Magnesia Carbon Brick
At Henan Jianhong Refractory Materials Co., Ltd., we are committed to delivering premium-grade Silica Brick that meet the highest industry standards. Our quality assurance process is designed to ensure each product offers consistent performance, long service life, and maximum thermal efficiency.
The key quality tests typically include:
| Test items | Test Description | Testing standards |
|---|---|---|
| Bulk Density (BD) | Measures the compactness of the brick. High density often correlates with better strength and durability. | ASTM C133 |
| Apparent Porosity (AP) | Indicates the brick's ability to resist slag and gas penetration. Lower porosity is preferred for corrosive environments. | ASTM C20 |
| Cold Crushing Strength (CCS) | Indicates the brick's ability to resist slag and gas penetration. Lower porosity is preferred for corrosive environments. | ASTM C133 |
| Refractoriness (RUL & PCE) | RUL (Refractoriness Under Load): Measures the temperature at which the brick deforms under load. | ASTM C24 |
| PCE (Pyrometric Cone Equivalent): Indicates the maximum temperature the brick can withstand without melting. | ||
| Thermal Shock Resistance | Evaluates the ability to withstand rapid temperature changes without cracking. | ASTM C1171 |
| Thermal Conductivity | Assess insulation performance — lower conductivity is ideal for insulating bricks, while higher values suit heat-transfer zones. | ASTM C1171 |
| Chemical Composition Test | Check the amounts of key ingredients like aluminum oxide (Al₂O₃), silicon dioxide (SiO₂), and magnesium oxide (MgO) to make sure they meet the required levels for the intended use. | ISO 12677 |
| Slag Resistance/Erosion Resistance | Evaluate the resistance to slag or chemical media. | ASTM C24 |
| Reburn line Change Rate | Volume stability after high temperature heating. | ASTM C38 |
| Dimension Inspection | Measure the length, width, and thickness of the bricks to make sure the size error is within ±1mm. This ensures the bricks match customer requirements and fit accurately during installation. | ISO 5019-1 |
| Surface Appearance Tests | Surface cracks.Edge chipping.Consistency in color and finish. | ISO 5019-1 |
| Packaging Tests | Packaging is inspected for export compliance and damage protection |
Through this meticulous testing process, we ensure that our refractory bricks meet the highest standards of quality, reliability, and performance, making them ideal for various applications in various industries.
