Product Description

Ceramic Fiber Blanket Molten Metal Ladle Lining High Temperature Thermal Insulation Roll

Product Description

Ceramic Fiber Blanket, also known as Aluminum Silicate Fiber Blanket or Alumina-Silicate Needled Blanket, is a flexible high-temperature insulation material made from high-purity alumina-silicate fibers through a specialized needling process. This mechanical interlocking technique eliminates the need for organic binders, creating a durable blanket with excellent tensile strength and reliable thermal performance at elevated temperatures.

In molten metal handling, the blanket is used to line ladle shells, cover tundish surfaces and wrap transfer runners. Its low thermal conductivity holds heat in the melt, reducing the temperature drop between the furnace and the casting station.

The needled fiber structure resists thermal shock, vibration and molten metal splash, and it does not wet or degrade on contact with molten metal. That keeps the lining stable through repeated pour cycles and extends service life.

Non-combustible and chemically stable, the blanket also shields workers and equipment from radiant heat, making it a dependable insulation layer for foundry and steelmaking operations.

Product Features

High Temperature Resistance – Handles radiant heat from molten metal with a classification temperature up to 1260°C.

Excellent Thermal Insulation – Low thermal conductivity holds heat in the melt and cuts heat loss through ladle and tundish walls.

Molten Metal Ladle Lining – Flexible roll wraps curved ladle shells and covers tundish surfaces for full-contact insulation.

Non Wetting Surface – Does not wet or degrade when exposed to molten metal splash, keeping the lining intact.

Needled Fiber Blanket – Mechanically interlocked alumina-silicate fibers stay together under vibration and thermal cycling.
