Get PriceFiberglass furnaces are designed for continuous glass melting and fiber drawing operations. Compared with rock wool and basalt melting furnaces, fiberglass furnaces require cleaner melting environments, more stable temperatures, and higher resistance to glass liquid contamination. Because furnace stability directly affects fiber quality and production efficiency, refractory materials used in fiberglass furnaces must provide excellent corrosion resistance, dimensional stability, and long service life. Kerui Refractory provides refractory solutions for fiberglass furnaces, including glass contact refractories, furnace roof systems, insulation structures, and maintenance support.
| Furnace Area | Main Damage Mechanism | Recommended Refractory Materials |
| Charging Area | Thermal shock, abrasion | High Alumina Brick / Wear Resistant Castable |
| Furnace Roof | High temperature radiation | Silica Brick / Ceramic Fiber Module |
| Melting Tank | Glass corrosion, molten penetration | Fused Cast AZS Brick / Zircon Brick |
| Glass Line | Glass erosion, chemical attack | AZS Brick / Zircon Brick |
| Burner Area | Flame erosion, thermal cycling | Mullite Castable / Low Cement Castable |
| Forehearth | Temperature fluctuation | Mullite Brick / Corundum Castable |
| Working End | Glass flow erosion | AZS Brick / Silicon Carbide Brick |
| Flue System | Heat loss, gas erosion | Insulating Fire Brick / Lightweight Castable |
The charging area is affected by repeated thermal shock and mechanical impact from raw material feeding.
The furnace roof operates under long-term high-temperature radiation and requires stable insulation performance.
The melting tank is continuously exposed to molten glass and severe chemical corrosion.
The glass line area is exposed to molten glass fluctuation and long-term chemical attack.
The burner area experiences direct flame exposure and rapid temperature changes.
The forehearth and working end require stable thermal conditions to maintain consistent glass flow and fiber quality.
Kerui Refractory provides customized refractory support for fiberglass furnace projects, including:
To provide suitable refractory recommendations, the following information is recommended:
| Required Information | Description |
| Furnace Condition | New project / Repair / Rebuild |
| Furnace Type | Fiberglass tank furnace / Electric melting furnace |
| Furnace Dimensions | Furnace size and lining structure |
| Operating Temperature | Working temperature range |
| Glass Composition | E-glass, C-glass, basalt additive, etc. |
| Current Refractory | Existing lining materials |
| Main Problems | Glass corrosion, cracking, erosion, leakage |
| Damaged Area | Tank, glass line, forehearth, roof, etc. |
Based on furnace operating conditions and glass composition, Kerui Refractory can provide optimized refractory selection and complete technical support solutions.
