Benefits and Application Area of Ceramic Fiber Blanket

One of the most popular insulation materials used these days include Ceramic fiber blanket is a lightweight needled blanket that is extensively used in a range of thermal insulation applications. The material is preferred due to its superior insulation performance and low thermal conductivity. It is manufactured using double needling and spinning techniques.

Made of silica, alumina and zirconia, it is a good insulator with low shrinkage. The material does not produce any fumes, as it is organic in nature. The material is often used in environments that expose it to chemical reactions, as it remains unaffected.

Ceramic Fiber Blanket

Ceramic fiber blanket retains its thermal properties even after getting wet by water, steam or other liquids. The material is used for wrapping fire protection applications and structural steel. You can get it in a variety of chemical compositions, thicknesses, and density combinations.

Here are some of the benefits and application area listed:

Low thermal conductivity: The ceramic fiber blanket has low thermal conductivity, so it can be used in the sidewall of extremely high temperature furnaces. It prevents heat loss and it has low heat storage as well as low thermal capacity.

Lightweight: The product is light in weight, which makes construction easy. The material has no expansion and it can be cut according to the size requirements at the site. The damaged or broken ceramic fiber blanket can be repaired or removed without removing the entire blanket. This leads to huge saving.

Low bulk density: It has lower bulk density as compared to the insulation brick. Being thinner than the regular refractory material, the ceramic fiber blanket reduces the volume of the masonry and the thickness of the furnace; thus, helping you save on construction materials.

Being soft and flexible ceramic fiber blanket remains protected from the mechanical shocks and rapid temperature variations. The fiber is available in different grades, which are used differently

Do you know real use of high alumina bricks in Industries?

Do you know that the working of steel industry and blast furnaces mainly depend upon a raw material? If not, here is the answer. The raw material is known as High alumina bricks.

What is a high alumina brick?

A high Alumina brick is a raw material which is used in several industries including refractories and steel plants. In fact high alumina bricks are a key ingredient in most of the modern steel plants across the globe without which steel manufacturing is not possible.

Use of high alumina bricks in Industries

Now, you may wonder how a small alumina brick can be so much useful to one of the major industries in the world.

Here is the answer. If you have ever visited a steel plant, you would have surely seen the blast furnaces and steel ladles. The linings for the blast furnaces and other parts in the steel industry are built using high alumina bricks.

Apart from these areas. High alumina bricks are used in areas of steel industry like

  • tap holes,
  • troughs,
  • side gate plates and
  • nozzles
  • electric arc furnaces
  • torpedo cars etc.

In the blast furnace linings, the percentage of high alumina bricks is 60 to 75%. The bottom and hearth part of the blast furnace is lined using the high alumina bricks.

The linings protect the carbon bricks and increase the service life of the blast furnaces, thus helping steel plant business to reduce cost on service and maintenance.

Use of high alumina bricks in tapholes

In the years that have passed by, the number of blast furnaces has decreased, but the production of steel and iron manufacturing has not decreased. Why? Because, the steel and iron manufacturers across the world have found innovative techniques to improve the efficiency of their furnaces.

The high alumina bricks are one of the key ingredients which have helped them to yield higher results within a short time. The tap hole mud are made up of high alumina bricks which can withstand high temperatures. So the bricks help the blast furnaces to produce higher yields.

There are many high alumina bricks manufacturers who produce it for steel and iron industry across India and around the world. Choose them wisely.
