Our ceramic fiber module is available in three precision-engineered temperature grades, tailored to diverse heat intensity requirements:
- 1260℃ (2300℉): Standard-grade for medium-high heat applications (e.g., heat treatment furnaces, ceramic sintering kilns).
- 1400℃ (2550℉): High-alumina grade for extreme heat environments (e.g., metallurgical electric arc furnaces, glass melting furnaces).
- 1430℃ (2600℉): Zirconia-enhanced grade for ultra-high heat and corrosion resistance (e.g., petrochemical cracking furnaces, aerospace testing furnaces).
Beyond temperature versatility, we offer full customization to match your furnace design: irregular-shaped modules, ceramic fiber cut blocks, folded blocks, and compatible SS304/SS310 stainless steel anchors in various sizes. The pre-compressed manufacturing process ensures dimensional precision with minimal error, allowing seamless adaptation to complex furnace profiles—from straight walls to curved tops and large-span structures.
The performance of Highland Refractory® Ceramic Fiber Module starts with rigorous raw material management, ensuring low thermal shrinkage and long-term reliability:
- We use high-quality Highland Refractory ceramic fiber blanket as the base material, with impurities reduced to less than 1% through multi-stage production control. Excess impurities are a leading cause of grain coarsening, increased linear shrinkage, and shortened service life—our strict oversight eliminates this risk.
- The ultra-pure composition results in a bright white appearance and exceptional stability: linear shrinkage is below 2% at 1200℃, maintaining structural integrity even after prolonged high-temperature exposure.
- Imported high-speed centrifuges (11,000 RPM) maximize fiber formation rate, producing blanket with uniform thickness, slag ball content below 10%, and superior flatness. Slag ball content directly impacts thermal conductivity—our low-slag design delivers a mere 0.22 W/mK at 1000℃, outperforming conventional insulation materials like lightweight refractory bricks.
We integrate proprietary technology with precision manufacturing to ensure consistent quality and performance:
- Our self-developed double-sided internal needle punching process, paired with daily needle panel replacement, ensures uniform needle patterns. This enhances the ceramic fiber blanket’s tensile strength to over 70 Kpa, ensuring structural stability during installation and use.
- The module is crafted by folding cut ceramic fiber blanket into fixed-size molds, followed by compression with a 5-ton press and bundling. This pre-compressed design gives the module excellent elasticity—after furnace lining installation, the module expands to form a seamless joint, compensating for fiber shrinkage and boosting insulation efficiency.
- Strict production process control ensures fiber distribution uniformity and consistent compression density, resulting in modules with smooth surfaces, precise dimensions, and reliable performance across batches.
Every batch of Highland Refractory® Ceramic Fiber Module undergoes comprehensive quality checks to ensure industrial-grade reliability:
- Dedicated quality inspectors oversee each production stage, with detailed test reports (covering thermal conductivity, shrinkage, tensile strength, and density) provided before shipment—validating compliance with international standards.
- We accept third-party inspections (e.g., SGS, BV) to verify product quality, giving you full confidence in cross-border procurement and project compliance.
- Production adheres to ISO 9000 quality management system standards, ensuring consistency and traceability for large-scale orders.
- Each module is weighed before packaging to guarantee actual weight exceeds theoretical weight, eliminating shortages and ensuring value for money.
- Packaging consists of 5-ply kraft paper outer cartons and moisture-proof plastic inner bags, protecting against humidity and physical damage during long-distance sea, air, or land transportation.
Highland Refractory® Ceramic Fiber Module has a significantly lower density than traditional insulation materials: it is 75% lighter than lightweight refractory brick linings and 90% lighter than lightweight castable linings. This drastically reduces the furnace’s structural load, minimizing wear on furnace shells, supports, and foundations—extending overall furnace service life by 20-30%.
With a heat capacity only one-tenth that of lightweight castables and traditional refractories, our module enables rapid furnace heating and cooling. This cuts preheating time by 30-50%, reducing energy consumption (e.g., gas, electricity) and lowering operational costs. For batch-type furnaces, this translates to faster production cycles, higher throughput, and significant long-term energy savings.
At 1000℃, the module’s thermal conductivity is just 0.22 W/mK—significantly lower than conventional insulation materials. This minimizes heat loss through furnace walls, maintaining stable internal temperatures, reducing energy waste, and ensuring uniform heating of workpieces. Industrial trials show a 15-25% reduction in energy consumption after upgrading to Highland Refractory® Ceramic Fiber Modules.
The module’s inherent flexibility and elasticity make it highly resistant to thermal and mechanical shock. It withstands rapid temperature fluctuations (e.g., furnace startup/shutdown) and high-velocity air scouring without cracking, shedding, or structural damage. This reliability is critical for harsh environments like metallurgical furnaces, petrochemical reactors, and waste incinerators.
As a neutral or weakly acidic material, the module resists corrosion from weak acids, weak bases, water, oil, and steam. It is not infiltrated by metals like lead, aluminum, or copper, and only reacts with strong acids and alkalis—ensuring long-term stability in diverse industrial environments.
The pre-compressed design ensures modules expand after installation to form a gap-free, seamless lining. This eliminates heat leakage through gaps, enhances insulation efficiency, and prevents hot spots—critical for maintaining furnace performance and workpiece quality.
We offer four specialized installation configurations to adapt to different furnace structures, ensuring easy installation, firm fixation, and convenient maintenance:
Fixed via bolts welded to the furnace shell and hoisting slides embedded in the module, this method offers:
- Individual module fixation: Each unit can be disassembled and replaced separately, simplifying maintenance and reducing downtime.
- Flexible arrangement: Can be installed in a “parquet” pattern or aligned along the folding direction to fit complex furnace shapes.
- Secure attachment: Each module is paired with a set of bolts and nuts, ensuring stable lining integrity even in high-vibration environments.
- Ideal for: Furnace tops, large-span structures, and areas requiring frequent maintenance.
Fixed with angle iron anchors and screws, connecting modules to furnace wall steel plates:
- Easy maintenance: Individual modules are removable for replacement without disrupting the entire lining.
- Flexible layout: Supports parquet or directional alignment installation, adapting to irregular furnace walls.
- Customizable modules: Can be processed into combined modules with blanket strips or special shapes for unique furnace profiles.
- Superior insulation: Large gaps between anchors and high-temperature surfaces, plus minimal contact points with the furnace shell, reduce heat transfer and energy loss.
- Ideal for: Furnace walls, tops, and medium-to-large industrial furnaces.
Installed on-site with screws, featuring a simplified anchor structure:
- Fast construction: Suitable for large-area straight furnace walls, reducing installation time by 30% compared to anchored types.
- Efficient insulation: Minimal anchor contact with the furnace shell minimizes heat loss, enhancing energy efficiency.
- Integrated lining: Adjacent modules are connected via screws to form a single unit, requiring directional alignment along the folding direction for structural integrity.
Composed of two identical modules with heat-resistant alloy steel tubes passing through, welded to the furnace wall via bolts:
- Seamless lining: Tight contact between steel plates and modules ensures a flat, uniform lining with consistent thickness and aesthetic appeal.
- Balanced resilience: Equal rebound force in two directions guarantees lining tightness and gap-free performance.
- Secure fixation: Independent fastening with bolts and steel tubes extends module service life and prevents displacement.
- Flexible installation: Supports parquet or directional alignment, with easy module replacement for maintenance.
