In industrial applications such as glass furnaces, cement kilns, and electric arc furnaces, efficient thermal insulation is no longer optional—it’s a strategic necessity. Poor insulation leads to energy waste, increased operational costs, and reduced equipment lifespan. At Zhengzhou Rongsheng Refractory Materials Co., Ltd., we’ve engineered a proven solution: lightweight fireclay insulating bricks that combine high porosity, low density, and exceptional mechanical strength—delivering real-world performance gains for global clients.
Our bricks are made from premium-quality clay with an aluminum oxide (Al₂O₃) content between 30–40%, ensuring optimal refractoriness up to 1350°C while maintaining structural integrity under thermal cycling stress. The manufacturing process includes precise drying and controlled sintering at 1100–1250°C, resulting in:
| Property | Value |
|---|---|
| Thermal Conductivity (W/m·K) | 0.6–0.8 @ 1000°C |
| Bulk Density (g/cm³) | 0.8–1.2 |
| Compressive Strength (MPa) | ≥ 0.8 MPa (after firing) |
These specs aren’t just numbers—they translate into measurable savings. One European glass manufacturer reported a 12% reduction in fuel consumption after switching to our custom-grade bricks in their melting tank, saving over €45,000 annually.
Unlike off-the-shelf solutions, our bricks are tailored to your furnace geometry, operating temperature profile, and load-bearing requirements. Whether you need non-standard dimensions (e.g., 230x115x75mm or custom molded shapes), enhanced thermal shock resistance, or compliance with regional standards like EN 1648 or ASTM C150, our team delivers within 3–4 weeks from order confirmation.
We’ve supported clients across the Middle East, Southeast Asia, and North America—from small-scale ceramic producers to large steel plants—by adjusting pore size distribution, adding stabilizers for vibration resistance, or optimizing thermal conductivity curves based on actual furnace data.
This isn’t just about material science—it’s about partnership. Our engineers work directly with your technical team during the design phase to ensure seamless integration into existing systems. No guesswork. No downtime. Just predictable results backed by real case studies and factory audits.
