Types of Fire Bricks
If you have a fireplace in your home, you may have noticed fire bricks.fire bricks They are light and insulating and can be used to keep the heat of the fire from damaging the interior of your house. There are many different types of fire bricks available. These products are used in many applications, such as in furnaces, in glass manufacturing, and in construction.
Fire bricks are manufactured in a similar way to ordinary bricks. The only difference is that they are made from a variety of materials, including clay and non-metallic minerals. They are typically fired in a kiln until they are partially vitrified. In addition to the mineral components, they also contain other chemical additives.
Typical fire bricks contain silica and alumina. Other constituents, such as ferric oxide, are used to help ensure the brick remains stable when subjected to high temperatures. Generally, the more alumina in the composition of the firebrick, the harder it is. A higher alumina content can also increase the amount of time before re-lining is required. This is due to the alumina's low thermal conductivity.
A typical fire brick is comprised of fifty to seventy percent silica and twenty to forty percent alumina. Refractory bricks are generally bonded together with refractory mortar. Typically, these bricks are used in heating and cooling equipment, such as furnaces, kilns, and boilers.
Depending on the application, refractory bricks have varying properties. They are usually bonded together with refractory mortar and have a lower thermal conductivity, so they insulate better and provide better insulation. For example, the refractory bricks in a wood burning kiln are lighter and softer than the refractory bricks in metallurgical applications, such as a steel mill. It is important to note that these firebricks can be damaged by moisture or excessive changes in temperature.
Firebricks have the capability of preventing heat from passing through, but they have poor soundproofing qualities. Nevertheless, they are ideal for use in a fire pit or a fireplace. Several fire bricks can be installed together in the same space, reducing the cost of a building.
Firebricks can be stained during the manufacturing process, and can be made to fit your specific requirements. They are normally sold in standard sizes. You can also order them in a custom shape. Some of the common shapes include the wedge, arch, and side skew. Usually, the wedge shape tapers down on one end, whereas the arch shape rises up to form the top of an arch. Side skew can be used to make arched roofs, such as those for a sprung barrel.
Another type of firebrick is acidic fire brick. Specifically, these bricks are designed to withstand the acidic effects of weather and chemicals. Normally, acid bricks are burned at high temperatures for a long period of time. However, they can be adapted for use in applications requiring additional acid resistance.
The most commonly used inner linings are silica bricks. The silica content can range from sixty to seventy percent. Adding silica to natural fire clay will increase the acid resistance of the brick, and can extend the amount of time before re-lining.
