The firebrick is a block of refractory materials used in lining furnaces, kilns, fireboxes, and fireplaces. The firebrick is designed mainly to withstand high heat, but should also usually have a low thermal conductivity to save energy. Usually dense firebricks are used in applications with extreme ...

Normal Firebrick is not good insulators. A special insulating Firebrick of highly porous fireclay or kaolin has low conductivity and low heat content but a melting point of only about 1,600°F to 2,800°F (870°C-1,540°C). Density is lower 1.3g/cm3, it is light weight Firebrick or insulating brick. ... Read More

In the other, less harsh situations, such as a natural gas fired kiln, more porous bricks are a better choice. They are weaker, but they are much lighter, easier to form, and insulate far better than dense firebricks. In any case, firebricks should not spall under rapid temperature change, and their ...

When firebrick is used to make load-bearing walls, the walls on the lower floors of a structure must support the weight of the upper floors; thus, the taller the structure, the thicker the walls must be on the lower floors. For example, Chicago’s Monadnock Building, which opened in 1896, is a ... Read More

Boiler refractory care requires periodic inspection and repair of the refractory materials surface. One of the most critical parts of a boiler is the rear door, and that is one place where the condition of refractory cement should be given special attention. The person inspecting it should look for ... Read More

Low cement castable is prepared with a lower amount of cement than the standard dense castable is normally created with. This type of refractory castable fluctuate in alumina content, which provides exceptional physical properties, including low porosity, great abrasion properties and high vigour. ... Read More

The product that we supply is the castable refractories that are low density. These insulating castables pose very low thermal conductivity and are utilized for either high temperature face work or when used for a backup lining, which is found behind dense castables or firebrick work. Here, the ... Read More

Fire clay is a type of clay which is used in the production of heat resistant clay items, such as the fire clay brick and the crucibles used in metals manufacturing. This type of clay is commonly mined from areas around coal mines, although other natural deposits are also available as potential ... Read More

If you are tryting to choose the best refractory brick for any project, you must first identify the purpose of the brick. If the refractory brick is destined for heating or cooking, you may want to follow the general consensus and choose a medium-grade fire brick. Rongsheng Refractory will provide ... Read More

Some places where fire brick can appear include: fireplaces, wood stoves, cremation furnaces, ceramic kilns, furnaces, forges, and some types of ovens. The earliest refractory bricks are developed around the 1800s, with several inventors contributing radical reworkings to make such products safer ... Read More
