Product Definition
High-temperature resistant aluminum silicate insulation blanket is a flexible thermal insulation equipment made with aluminum silicate fiber (ceramic fiber) as the core material, combined with alkali-free glass cloth/stainless steel foil surface layer. It blocks heat conduction through fiber interwoven structure, withstanding temperatures from 1260℃ to 1600℃. Core features include:
- Temperature resistance: Long-term use temperature 1260℃ (zirconium type up to 1600℃), instantaneous temperature resistance 1800℃.
- Ultra-low thermal conductivity: Thermal conductivity coefficient 0.035-0.08W/(m·K) (at 600℃), 40% lower than rock wool.
- Flexible and lightweight: Can be rolled and laid, surface density ≤3kg/m² (traditional refractory bricks >20kg/m²).
- Industry positioning: Replaces traditional rigid refractory materials (such as ceramic fiber boards), solving insulation challenges for irregular-shaped equipment.

Industry Application Location Energy-saving Benefits Metallurgy Ladle cover, melting furnace door curtain Reduces furnace temperature loss by 30%, energy consumption per ton of steel reduced by 8% Chemical Cracking furnace pipes, reactor outer wrapping Surface temperature reduced from 600℃ to 80℃, prevents burns Power Gas turbine compartment, boiler inspection port Reduces heat loss by 500,000 kcal/hour Glass Manufacturing Top of tin bath, annealing kiln sealing Improves glass yield by 3% (temperature fluctuation <±5℃) 2. Domestic and International Innovative Applications
Region Featured Scenario Product Form Differences China Electric furnace steelmaking (coverage >70%) Surface coated with aluminum foil reflective layer (reflectivity >90%) Europe and America Engine test bench insulation Composite silicon carbide coating (resistant to high-speed airflow erosion) Middle East Petroleum coking plant high-temperature pipelines Added hydrogen sulfide corrosion protection layer Japan Waste incineration furnace secondary combustion chamber sealing Ultra-thin (1.2mm) foldable design Five Core Advantages
1. Energy Saving and Consumption Reduction
- Covering 1200℃ ladle can reduce heat loss by 35%, saving over ¥500,000 annually in gas costs (based on 10-ton furnace).
2. Safety Protection
- Surface temperature reduced from 600℃ to 80℃ (measured), preventing worker burns, compliant with OSHA heat contact standards.
3. Convenient Construction
- Supports cutting, sewing, and hook-and-loop fastening, bending radius ≤50mm, suitable for irregular-shaped equipment (such as valves).
4. Long Service Life and Cost-effectiveness
- Thermal shock resistance cycles >1000 times (traditional ceramic plates only 300 times), lifespan 5-8 years, maintenance costs reduced by 60%.
5. Environmental Compliance
- Asbestos-free, VOC-free, certified by EU REACH and US ASTM C795.
Installation and Usage Guide
1. Installation Process
Steps Key Points Illustration Suggestions Measurement and Cutting Leave a 10cm margin according to equipment shape, avoid bolt holes. Cutting template diagram for steel ladle coverage. Layered Laying Multiple layers staggered joints (gap ≤ 2mm), overlap width ≥ 15cm. Close-up of overlap seam (sealed with aluminum foil tape). Fixing and Sealing Stainless steel buckle strap binding + high-temperature adhesive (>1000℃). Dynamic image of buckle strap tightening. Inspection and Maintenance Regularly remove surface dust (blow with compressed air). Thermal imaging comparison before and after cleaning. 2. Safety Warnings
- No bare-hand operation: fiber dust may harm skin, protective gloves and goggles must be worn.
- Wet removal: spray water mist before removing old blankets to prevent dust dispersion.
