In the competitive world of coke production, even small improvements in refractory performance can lead to significant gains in efficiency and profitability. One of our long-term clients—based in northern China—recently upgraded their furnace lining from standard silicon brick to high-density, low-porosity silicon brick (density >2.38 g/cm³, porosity <16%) and saw immediate results.
Before the upgrade, the client reported frequent thermal spalling and accelerated wear due to inconsistent density and higher porosity (average 22%) in older-grade bricks. This meant:
Post-upgrade data shows dramatic improvements:
| Metric | Before Upgrade | After Upgrade |
|---|---|---|
| Furnace Life (Years) | 7 | 12+ |
| Thermal Conductivity Improvement | Baseline | +15% avg. |
| Maintenance Frequency | Every 6–8 months | Every 14–18 months |
“We were spending more on maintenance than we thought. With this new brick, we’re not just saving time—we’re gaining control over our entire production rhythm.” — Zhang Wei, Plant Manager at Shanxi Coking Co.
The key takeaway? It’s not about replacing bricks—it’s about investing in materials that perform under real-world stress. These bricks reduce heat loss, resist thermal shock, and maintain structural integrity longer. That means less labor, fewer interruptions, and consistent quality output.
For manufacturers facing rising operational costs or aging infrastructure, the decision isn’t whether to act—it’s how fast you can move.
