Basic Introduction of Soft Fire Bricks for Sale

Soft fire brick, also known as lightweight fire brick or insulating fire brick, is a type of refractory material commonly used in applications that require thermal insulation at moderate to high temperatures. Soft fire bricks include lightweight aggregates such as expanded clay and perlite, mixed with a refractory binder. The combination of these materials results in a porous structure. These air pockets act as thermal insulators, to reduce heat transfer through the bricks. Compared to dense or heavy fire bricks, soft fire bricks are characterized by their low bulk density and excellent insulating properties.

Outstanding Thermal Insulation

Kerui Refractory soft fire bricks are famous for their outstanding thermal insulation properties. They have a low thermal conductivity, which helps to minimize heat transfer and improve energy efficiency. This feature allows for better temperature control to reduce heat loss, and ultimately lowers energy consumption.

Excellent High Temperature Resistance

These bricks are specifically designed to withstand high temperatures. Kerui soft fire bricks have a high melting point and excellent thermal stability. This makes them suitable for applications where insulation is required in extreme heat environments such as furnaces, kilns.

Lightweight and Low Bulk Density

Kerui soft fire bricks have a low bulk density, which makes them lightweight and easy to handle during installation. Besides, their weight simplifies transportation, lowers labor costs, and facilitates faster construction or repair work. Thus, this is convenient for customers to use.

Low Heat Storage

Soft fire bricks have a low heat storage capacity, which means they quickly absorb and release heat. Besides, this property allows for rapid temperature changes to reduce thermal inertia and enable more precise temperature control during heating and cooling.

Good Thermal Shock Resistance

Kerui soft fire bricks exhibit excellent resistance to thermal shock. For example, they can withstand rapid temperature fluctuations without cracking or spalling to ensure long-term durability and reliable insulation performance.

Stable Chemical Stability

Soft fire bricks have good chemical stability, making them resistant to chemical reactions and corrosion. Meanwhile, this feature ensures their longevity in aggressive environments where exposure to chemicals or gases is common.
