Ceramic Fiber Insulation: Manufacturing Ceramic Blankets

Supplied in rolls, ceramic fiber insulation blanket is highly formable, which makes it the perfect insulation for refractory machinery. It can fill voids, encapsulate machinery, and even be integrated into heating components.

Ceramic Fiber Insulation: Manufacturing Ceramic Blanket

Made primarily from high-temperature insulation wool produced from synthetic materials, ceramic fiber insulation can withstand temperatures that consistently exceed 1200°C. The synthetic material is densified, treated, and machined prior to application.

Ceramic fiber insulation is created from high-quality refractory ceramic fibers made from alumina silicate. The process takes various combinations of pure aluminum oxide (AL2O3) and silicon dioxide (SiO2) and melts them in an industrial furnace.

Ceramic fiber blanket is made by “needling” spun ceramic fibers that are longer and wider than fibers made via the blowing process. These fibers give spun ceramic fiber blanket higher rupture strength and greater tensile strength.

The Advantages of Ceramic Fiber Insulation Blanket

Ceramic fiber insulation blanket is malleable, an attribute users can amplify by treating the insulation with inorganic bonding agents. They can pack it into plastic to preserve high moisture levels before application.

The material has superior heat-controlling properties, which is why it works so well as insulation. Additionally, it can be stored at low heat and is entirely resistant to thermal shock.

Typical Applications

The ceramic fiber insulation blanket is frequently used as an industrial insulation material in addition to its uses in heat processing applications and high-temperature insulation because it has low thermal conductivity.

Additionally, the blanket provides sound absorption, contains no asbestos, and can be repaired simply and quickly. No curing or drying is required to create ceramic fiber blanket insulation.

The blanket also finds use in the ceramics industry for kiln car insulation and seals. The steel industry also widely uses it for heat treatment, annealing furnaces, and furnace door linings and seals. It can also facilitate furnace hot face repairs and serve as a cover for reheating furnaces and ladles.

Ceramic fiber insulation is used in the refining and petrochemical industry as a reformer and pyrolysis lining and for tube seals, gaskets, and expansion joints. Other uses include high-temperature pipe, duct, and turbine insulation as well as in crude oil heater linings.

The insulation is often used for reusable turbine coverings in the power generation industry as well as in the insulation of commercial dryers and ovens.
