Excellent heat stability
Fire Bricks can maintain stable structure and performance in high temperature environments, and have excellent high temperature resistance and thermal insulation properties.
Excellent Chemical Resistance
Fire bricks are made from materials that are resistant to acids, bases, and other corrosive materials, making them ideal for chemical plants and other corrosive environments.
Low thermal conductivity
The lower the thermal conductivity of Fire Bricks, the less likely they are to transfer heat, and the better their thermal insulation and energy-saving effects. With the same thickness, they have better thermal insulation effects and can effectively reduce heat transfer, thereby improving the thermal efficiency and safety of equipment.

Basic refractory bricks that include dolomite blocks, bauxite blocks, and Magnesite blocks
Acidic refractory bricks that include ordinary fire block, Ganister block, and silica bauxite block
Neutral refractory bricks include Chrome magnesite blocks, Spinal blocks, Forsterite blocks Chromium blocks, and Carborundum.
Silica: Silica (SiO2) becomes soft at about 2800℉ and finally fuses and becomes a glassy substance at about 3200℉. It melts around 3300℉. This high softening and melting point has established it as the principal material for the production of refractory bricks.
Alumina: Alumina (Al2O3) has even higher softening and fusion temperature than silica. It melts at about 3800℉. It is, therefore, used in combination with silica.
Lime, Magnesia, Iron oxide and Alkalis: The presence of these detrimental components acts as fluxes to lower the softening and fusion temperature.
Digging:
First comes digging when raw materials such as silica, clay, alumina, and magnesia are extracted from quarries or mines. These are chosen depending on the properties of the final refractory product created.
Weathering:
The extracted raw materials are exposed to weathering. This can help reduce moisture content and improve the durability. As a result it becomes easy to form acid proof bricks later.
Tempering:
The raw materials are mixed with water to form a plastic clay-like mixture. This mixture is then tempered, which involves kneading as well as rolling to achieve uniform consistency and eliminate any kind of air pockets.
Moulding:
Molds help shape any mixture into a desired brick form. The process of molding can be done via different methods like extrusion, pressing, or casting.
Burning:
The molded bricks are fired in kilns at very high temperatures starting from around 1300°C to 1800°C (2372°F to 3272°F). It depends on the type of brick as well as its application. This firing process results in a dense and durable refractory structure.
