Characteristics of High Heat Resistant Bricks

Heat resistant fire bricks possess several characteristic properties that make them suitable for high-temperature applications. It’s important to note that the specific characteristics of high temperature bricks can vary depending on the composition and manufacturing process. Different types of fire bricks, such as silica bricks, magnesia refractory bricks and high alumina bricks, may have slightly different properties tailored for specific applications and temperature ranges.

High Temperature Resistance

We design high heat resistant bricks to withstand extremely high temperatures without significant deformation or loss of strength. Therefore, they can typically withstand temperatures from 1250℃ (2282℉) to 1790℃ (3254℉) or even higher temperatures.

Chemical Resistance

Kerui heat resistant fire bricks can resist chemical attacks by molten metal, slag, gas and other corrosive substances. In addition, they are composed of materials that can withstand the chemical reactions and corrosive effects of these substances.

Low Thermal Conductivity

This feature helps minimize heat loss when operating industrial equipment. Furthermore, using Kerui refractory bricks within high-temperature equipment helps maintain more efficient heat transfer. This thereby reduces energy consumption.

Impact Resistance

In the industrial sector, we often subject wholesale refractory brick to mechanical forces such as abrasion and impact. However, Kerui refractory bricks are formulated to withstand such mechanical stresses and maintain their structural integrity.

Mechanical Strength

Our high temperature bricks have high mechanical strength. Therefore, it can withstand the weight of surrounding materials and the stresses generated during thermal expansion and contraction. Therefore, this ensures their structural integrity.

Dimensional Stability

Heat resistant fire bricks exhibit good dimensional stability even at extreme temperatures. This means they won’t expand, shrink or warp significantly. This, in turn, allows them to maintain their shape and fit into the device to which they are applied.
