Kerui uses fully automatic batching system and strong mixing machine to finish the preparation work. Fully automatic machine controls accurate weight and ratio of materials. Besides, the mixing machine will stir these materials for more than 20 minutes to get fine brick pulp. These steps are essential to ensure the performance of fire bricks you buy.

Kerui Mixing of Raw Materials

Shaping of Fire Bricks

Once the raw materials are thoroughly mixed, the next step is to shape them into the desired form of fire bricks. Kerui employs various shaping techniques, including extrusion, pressing, or casting, depending on the specific requirements of the fire brick design. At the same time, these techniques help create fire bricks with consistent dimensions and shapes.

Kerui Shaping of Fire Bricks

Drying of Fire Brick

Forme fire brick needs to be dried at a relatively low temperature. This step is to prevent cracking during subsequent high-temperature sintering. In addition, the excess moisture in the brick embryo will cause greater thermal stress in the subsequent process, which is not conducive to the formation of high-quality performance. Drying in advance can reduce energy loss.

Kerui Drying of Fire Brick

Sintering of Firebrick

The sintering process is one of the key steps in the manufacture of fire bricks. Through high-temperature sintering, the raw materials in the fire brick will be combined with each other to form a strong brick structure. And after a series of chemical reactions, the compactness, high temperature resistance and wear resistance of Kerui fire brick are all enhanced.

Main Purposes of Buying Fire Brick

Fire bricks are specifically designed and manufactured to withstand high temperatures and are commonly used in various applications. The main purposes of buying fire bricks include:

Linings of Kilns

High-temperature industries widely used fire bricks as linings in kilns, furnaces, and other high-temperature environments. For example, working temperature of Kerui corundum brick is about 1800℃ (3272℉). Meanwhile, these bricks provide insulation and protect the surrounding structure from the intense heat generated inside the kiln. The fire bricks are able to withstand extremely high temperatures. This property helps maintain the desired temperature uniformity and prevent heat loss, which ensures efficient operation of the kiln.

Tops of Kilns

The top of a kiln is an important area that requires heat resistance and durability. High-temperature industries used fire bricks to construct the top section of kilns to withstand the high temperatures generated inside. Fire bricks provide a strong and reliable barrier against heat. Thus, it’s useful to prevent damage to the kiln’s top structure and facilitate efficient heat retention. Many customers use Kerui fire brick to construct the top of their high temperature kilns and have realized goos results. You can also contact Kerui for a guide.

Bottoms of Kilns

The bottom of a kiln is subjected to extreme heat and direct contact with the materials being processed. Additionally, high-temperature industries utilized fire bricks in the construction of kiln bottoms due to their excellent heat resistance and durability. Meanwhile, Kerui fire bricks can protect the kiln’s base structure from the intense heat and corrosive effects of the materials being processed, which ensures a longer lifespan for the kiln. During the construction, professional refractory brick suppliers will offer technical guide.

Corners of Kilns

The corners of kilns are particularly vulnerable to stress and cracking due to thermal expansion and contraction. High-temperature industries are used fire bricks in the corners of kilns to provide structural stability and prevent cracking caused by temperature differentials. The high-temperature resistance and thermal shock resistance of fire bricks make them ideal for this application. Therefore, application of firebrick in cornores can ensure the longevity and integrity of the kiln’s corners. Please contact Kerui now to get suitable firebricks.

Walls of Kilns

Fire bricks form the primary construction material for the walls of kilns. The walls need to withstand the high temperatures generated inside the kiln while maintaining structural stability. Fire bricks offer excellent heat insulation and thermal shock resistance. Therefore, this is a strong guarantee that the kiln’s walls can withstand extreme conditions. With this fire brick lining, there is a stable temperature environment for efficient operation. Kerui provides all kinds of high quality lining bricks for wordwide customers.
