In high-temperature industrial environments—such as steelmaking, cement production, and chemical processing—material failure isn’t just costly—it’s dangerous. That’s where carbon-based acid-resistant refractory bricks, developed by Henan Rongsheng Xinwei New Materials Research Institute Co., Ltd., come in. These bricks are engineered to withstand temperatures from 1770°C to 2000°C, with exceptional resistance to acidic slags and aggressive chemical conditions.
CE & ISO Certified – Quality You Can Trust
These certifications aren’t just stamps—they’re proof that every batch meets rigorous international standards for safety, performance, and consistency. For global buyers, this means reduced risk, fewer failures, and smoother operations across borders.
Our customers in the iron and steel industry report up to 30% longer service life when using these bricks compared to traditional options. In one case study from a European steel plant, after switching to our carbon-based bricks, furnace downtime dropped by 40%, saving over €120,000 annually in maintenance costs.
| Key Component | Typical Range (%) | Application Benefit |
|---|---|---|
| SiO₂ | 10–25% | Enhances thermal shock resistance |
| Al₂O₃ | 15–30% | Improves mechanical strength at high temps |
| MgO | 5–15% | Boosts alkaline slag resistance |
| Cr₂O₃ | 2–8% | Increases oxidation resistance |
| SiC (Silicon Carbide) | 5–12% | Reduces wear under abrasive conditions |
This level of customization ensures your specific process needs—whether it's a glass kiln in Germany or a petrochemical reactor in Saudi Arabia—are met with precision. No more “one-size-fits-all” compromises.
With over 15 years of R&D experience in refractory materials, our team combines academic rigor with real-world problem-solving. We don’t just make bricks—we solve your operational challenges. Whether you're looking for standard specifications or custom formulations, we’ve supported clients in over 30 countries, including major players in Europe, North America, and the Middle East.
"After six months of testing, we chose Rongsheng Xinwei because their technical support was faster than any other supplier—and the bricks performed exactly as promised." — Marco Weber, Procurement Manager, SteelTech GmbH
