The 3000°F Ceramic Fiber Blanket is a high-performance, refractory insulation material designed to withstand extreme heat up to 3000°F (1650°C). Made from high-purity alumina-silica fibers (Al₂O₃ ≥72%), this high-temperature insulation blanket provides unparalleled heat resistance and durability, far exceeding the capabilities of traditional High Temperature Ceramic Fiber Blankets (which are typically rated for temperatures up to 2600°F/1425°C). It is engineered to address the unique challenges of extreme heat environments, making it the ideal choice for industries that require advanced thermal protection for critical applications.
Highland Refractory produces this premium Ceramic Fiber Blanket 3000 Degrees with low shot content (≤3%) and optimized fiber structure, tailored to industries like steel, non-ferrous metallurgy, and petrochemical, where extreme heat is a constant challenge.
Use 1: Steel Electric Arc Furnace (EAF) Insulation
The Electric Arc Furnace (EAF) is subjected to molten steel radiation at temperatures up to 3000°F (1650°C). The roof insulation layers and sidewall linings are in constant contact with this intense heat, making it essential to choose the right insulating material.
The 3000°F Ceramic Fiber Blanket can withstand these extreme temperatures without degrading. Its low thermal conductivity (≤0.18W/(m·K) at 1200°C) helps to reduce heat loss by 25%, outperforming traditional Refractory Ceramic Fiber Blankets.
Highland’s Ceramic Fiber Blanket 3000 Degrees (with thicknesses of 50-100mm) is specifically designed for EAF insulation, offering flame-retardant performance that meets UL94 V-0 standards for high heat and fire protection.
Use 2: Non-Ferrous Metallurgy (Titanium/Zirconium Smelting Furnaces)
In the non-ferrous metallurgy industry, particularly in the smelting of titanium and zirconium, furnaces experience extreme heat (up to 2900°F/1593°C) along with molten metal erosion. Conventional High Temperature Ceramic Fiber Blankets cannot handle these extreme conditions.
The 3000°F Ceramic Fiber Blanket offers both high-temperature resistance and the ability to withstand mild molten slag corrosion, making it ideal for smelting furnace linings and tapping channel insulation. Its high-alumina content (Al₂O₃ 75%) provides enhanced performance and extends the material’s service life up to 4 years.
Highland’s Ceramic Fiber Blanket 3000 Degrees is engineered to meet the needs of smelting furnaces in non-ferrous metallurgy, ensuring reliable insulation under extreme conditions.
Use 3: Petrochemical Gasifier Cores
In petrochemical gasifiers, the reaction zone is exposed to extreme heat (ranging from 2700°F to 2900°F/1482°C-1593°C) and high-pressure gas. The insulation needs to be flexible enough to adapt to irregular core shapes while providing robust heat resistance under high pressure.
The 3000°F Ceramic Fiber Blanket is an excellent choice as it can conform to the unique geometry of gasifier cores while maintaining its structural integrity. Its tensile strength ≥0.08MPa ensures that the blanket resists gas erosion and remains intact even in high-pressure environments.
Highland’s Ceramic Fiber Blanket 3000 Degrees is specially formulated for gasifier cores, delivering flexibility and superior heat protection in the most demanding petrochemical applications.
Use 4: Waste Incinerator High-Temp Chambers
The waste incinerator combustion chamber operates in extremely harsh conditions with temperatures reaching up to 2800°F (1538°C), and corrosive flue gases can degrade traditional insulation materials quickly.
The 3000°F Ceramic Fiber Blanket is designed to resist corrosive flue gases and extreme heat, with acid/alkali resistance that minimizes weight loss to ≤3% after 24 hours in 5% HCl. This makes it the perfect solution for combustion chamber linings, as it ensures long-lasting protection and significantly reduces maintenance frequency by 50% compared to standard refractories.
Highland’s Ceramic Fiber Blanket 3000 Degrees with anti-corrosion additives is engineered to withstand the harsh conditions in waste incinerators, reducing downtime and maintenance needs.
Use 5: Laboratory Extreme-High-Temp Test Furnaces
In laboratory applications, test furnaces often reach 3000°F (1650°C) for material performance testing. Standard High Temperature Ceramic Fiber Blankets do not provide enough insulation for these extreme conditions.
The 3000°F Ceramic Fiber Blanket ensures a uniform temperature (fluctuation ≤±5°C) inside the furnace, making it ideal for laboratory extreme-high-temp test furnaces. The flexibility and thermal shock resistance (≥100 cycles from 1200°C to 20°C) of this blanket allow it to perform reliably under frequent temperature changes.
Highland’s Ceramic Fiber Blanket 3000 Degrees (available in 25-50mm thicknesses) is CE-certified for safety, making it the optimal choice for high-precision testing environments.
Property 1: Ultra-High Temperature Resistance (3000°F/1650°C)
The 3000°F Ceramic Fiber Blanket excels in high-temperature environments, supporting applications such as Electric Arc Furnace (EAF) insulation and smelting furnaces with temperatures up to 2900°F (1593°C). This high-temp resistance makes it far superior to ordinary High Temperature Ceramic Fiber Blankets.
Property 2: Low Thermal Conductivity (≤0.18W/(m·K) at 1200°C)
This blanket’s low thermal conductivity is crucial in reducing energy loss in extreme heat settings like gasifiers and incinerators, where temperature retention is key for efficiency.
Property 3: Good Thermal Shock Stability (≥100 cycles from 1200°C to 20°C)
The 3000°F Ceramic Fiber Blanket offers exceptional thermal shock resistance, making it ideal for laboratory test furnaces and EAFs, where frequent start-stop cycles are common. Unlike rigid refractories, it maintains its integrity despite rapid temperature changes.
Highland Refractory optimizes these properties in Ceramic Fiber Blanket 3000 Degrees, utilizing higher alumina content for temperature resistance and anti-corrosion additives for harsh environments.
Step 1: Confirm equipment max temp (must ≤3000°F/1650°C)
If the operating temperature exceeds 3000°F, higher-grade refractories are necessary. For temperatures ≤3000°F, the 3000°F Ceramic Fiber Blanket is the optimal solution.
Step 2: Match thickness to insulation needs
For heavy insulation (e.g., EAF roof), choose 75-100mm thickness. For thin insulation (e.g., laboratory test furnace), select 25-50mm thickness.
Step 3: Check additional requirements
For corrosive environments (e.g., incinerators), select a corrosion-resistant grade. For high-pressure environments (e.g., gasifiers), choose a high-tensile grade.
Highland’s product spec sheets clearly mark temperature ranges, thickness, and additional features, making it easier to select the right solution for extreme heat environments.
The 3000°F Ceramic Fiber Blanket is the top choice for 5 extreme heat uses — from steel EAFs to laboratory test furnaces — thanks to its 3000°F temperature resistance, low thermal conductivity, and durability. It outperforms traditional High Temperature Ceramic Fiber Blankets and Refractory Ceramic Fiber Blankets in handling extreme heat and corrosive environments.
Highland Refractory produces Ceramic Fiber Blanket 3000 Degrees with high-purity raw materials (low shot content ≤3%) and strict quality control, offering custom thickness/cutting and on-site installation guidance for extreme-heat projects.
