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.

How Can You Use Light Weight Insulation Fire Bricks?

Insulation fire bricks manufacturer offers products which are delicate and light in weight. They can be effectively cut by handheld hack saw or some other hand instrument like etch or even bore. Shade of insulating bricks shifts however for the most part they come in shades from light chestnut to white, see pictures.

In refractory industries air is the best insulation and this is the reason insulation fire bricks have phenomenal protecting properties. Their body is made of little air spaces like honeycomb impact.

Insulation Bricks

Fire bricks manufacturers utilize light weight protection which is expansive, for the most part in modern and interest ovens warmed up with either electric winding components or gas burners, heaters, both for hot face covering or external move down warmth protection.

Try not to befuddle lightweight fire bricks with overwhelming thick fire bricks. Insulation bricks are headstrong as well and obviously withstand high temperatures go but for reason they have low warm conductivity and don’t retain the warmth well by any means.

Insulation fire bricks in light weight

Those are expectations for warmth protection. For example in the event that you utilized them for building of the hot face in a wood let go broiler the stove wouldn’t cook, on the grounds that it wouldn’t store and hold any warmth.

Insulation Fire bricks manufacturers and exporters utilize these insulation bricks on the external side to keep the absorbed warmth in the chamber’s body mass from getting away and accomplishing heavenly results. Which means all around protected broiler which will hold the retained warmth in its mass, where it ought to be to cook for long time?

Technical specification about bricks :

Bulk Density : 604 Kg/m³

Modulus of Rupture : 1.52MPa

Permanent Linear Change on reheating 24hrs @ 1280°C : 1.95%

Fire Bricks – Instance For Building Cooking Chambers in Wood Fired Ovens

In a current days they are called heavy dense Fire bricks however old manufacturers still call them fire clay blocks in light of the fact that they are made of straight forward fire clay.

Fire clay can be effectively situated out in the nature yet it must contain the right properties, suitable substance proportion of silica and alumina. A few shops call these blocks chimney bricks.

They are utilized for case for building cooking chamber in wood terminated stoves, for making chimneys, a wide range of flame boxes and wood radiators’ covering, linings in a little or the hugest mechanical heaters, and so on.

Fire clay bricks are thick having low porosity and even on different re-warming, they will keep going for long time.

Fire Clay Bricks Manufacturers

Some may mistake them for insulating lightweight fire bricks, those are utilized as a part of distinctive applications.

Dense fire bricks can be cut just with precious stone wheel appended to fast handheld edge processors, on a conventional building block saw or sliding drop saw for cutting blocks. Fire bricks can be slashed into equal parts effortlessly by utilizing block etch and a few hits with a heavier hammer.

It is fun and snappy yet might you need to accomplish exact pleasant cuts employ an exchange machine or purchase yourself in any event little size processor.

Before dipping so as to cut absorb the bricks water it in a can of water or in a wheelbarrow on the off chance that you had too much.

Leave the bricks in that water for 5 minutes least. The cutting jewel wheel will keep going you for quite a while if the fire bricks are cut wet in addition to you won’t breath in any dust, and obviously cutting gets a considerable measure less demanding and speedier!
