Soft brick and hard brick are two different types of refractory materials. In the industrial sector, the selection of appropriate refractory materials is critical to ensuring the safety and effectiveness of a structure. In addition, they play an important role in different industrial application scenarios. This article will compare refractory bricks and insulating bricks. Moreover, Kerui aims to help customers make informed decisions when choosing the right refractory bricks.
Refractory brick can withstand extremely high temperatures and maintain structural stability. In addition, it is also suitable for use in places where resistance to chemical reactions is required.
The high quality hard brick has good resistance to corrosive media such as acids and alkalis. That is to say, this makes them widely used in the chemical industry, metallurgy and furnace applications.
Kerui hard fire brick has high strength and impact resistance and can withstand external forces and vibrations. In other words, it can well protect the structural integrity of industrial equipment.
Because Kerui refractory fire brick uses special materials and manufacturing processes, long fire bricks have high durability. Therefore, it maintains stability and longevity over a long time.
Soft brick has good thermal insulation properties and can effectively reduce heat conduction and energy loss. This makes it play an important role in industrial insulation and energy conservation.
Insulation brick is usually made of lightweight, porous or insulating materials, so they are relatively lightweight. So, this makes the installation and handling process more convenient and efficient.
Due to the characteristics of soft fire brick, it has certain flexibility and earthquake resistance. Therefore, it can maintain the stability of the structure under the impact of other external forces.
Kerui uses environmentally friendly materials to make insulating soft fire brick, such as rock wool. These materials are environmentally friendly and do not release harmful substances.
The main component of soft refractory bricks is high-temperature fiber materials (such as ceramic fibre). The fibers are then interwoven and tied to form a loose structure. However, hard refractory bricks are made of refractory clay or other refractory materials sintered at high temperatures and have a.
The two types of bricks also differ in density and hardness. The density of soft fire bricks is low, usually between 0.5g/cm3 and 1.9g/cm3. However, the density of hard fire bricks is higher, usually between 1.9g/cm3 and 3.9g/cm3. Due to structural differences, soft refractory bricks are relatively soft, while hard refractory bricks are harder.
Kerui soft refractory bricks have excellent thermal insulation properties. They are suitable where good insulation and thermal insulation properties are required. However, hard refractory fire bricks for sale have a higher refractory temperature and are suitable for applications that need to withstand high temperatures and mechanical stress.
We often use soft fire bricks in industrial kilns, insulation layers of heating equipment, flue linings, etc. Because hard refractory bricks offer higher durability and mechanical strength. Therefore, we often use them in furnaces, furnace walls, furnace bottoms and other parts that are subject to high temperatures and mechanical impact.
Hopefully, this gives you a better idea of the difference between soft fire bricks and hard fire bricks. When choosing refractory bricks for a high-heat application, You may consider consulting Kerui experts for free help. That way, you can be sure that the fire bricks that you purchase will provide the proper levels of structural support and insulation.
