Product Description

High Alumina Ceramic Fiber Blanket Reheat Furnace Thermal Resistant Needled Roll

Product Description

High Alumina Ceramic Fiber Blanket is a needled insulation roll made from high-alumina fiber with a higher classification temperature. It is designed for reheat furnaces and refractory linings that operate beyond the reach of standard blankets.

The higher alumina content raises the melting point and improves resistance to thermal shock and chemical attack, so the blanket survives rapid temperature changes and aggressive furnace atmospheres. The needled structure keeps the fibers locked together for a dense, durable lining.

Non-combustible and free of organic binders, the blanket provides stable thermal protection and backup insulation for high-temperature refractory systems in metallurgical, ceramic and glass industries.

Product Features

High Alumina Ceramic Fiber – Elevated alumina content raises the classification temperature for extreme-heat service.

Extreme Temperature Resistance – Sustains continuous service near 1200°C with classification temperature up to 1400°C.

Reheat Furnace Lining Blanket – Acts as a reliable hot-face or backup layer behind refractory brick and castables.

Outstanding Thermal Shock Resistance – Handles rapid heating and cooling without cracking or spalling.

Excellent Chemical Stability – Resists most acids, alkalies and furnace gases for long service life.
