Benefits of Choosing Products from Reliable Fire Brick Manufacturers

High Temperature Stability
Thermal Conductivity
Thermal Shock Resistance
Chemical Resistance
Wear Resistance
High Mechanical Strength

Keep the Structure Stable

Firstly, fire bricks have excellent high temperature resistance. It can withstand extremely high temperatures without melting or deforming. Secondly, fire bricks have a low thermal expansion coefficient and can resist the generation of thermal stress. Besides, these properties make high heat fire brick an ideal lining material for high-temperature furnaces. Therefore, it ensures that the kiln structure remains stable during long-term operation.

Maintain Service Life

The firebrick supply of fire bricks manufacturers has excellent wear and corrosion resistance. So, we can use it for a long time in harsh working environments. The material composition and structural design of firebricks make them resistant to chemical attack and mechanical wear. They can withstand chemical corrosion, molten metal and exhaust gas attack at high temperatures. So, it extends the service life of the equipment and improves the energy efficiency of the furnace.

Protect the Surrounding Environment

First, the high-temperature resistance of fire bricks enables them to effectively isolate the heat generated by high-temperature processes. This prevents heat from being conducted in the surrounding environment and reduces thermal pollution. Secondly, fitting fire bricks can resist chemical erosion and block the spread of harmful gases and corrosive substances. This ensures the safety of the surrounding environment and reduces environmental pollution.

Advanced Fire Bricks Manufacturing Process of Fire Brick Manufacturers

Do you know how to make fire bricks or what are firebricks made of? Its production process is very complicated, and the most important thing is that every step of the production is very strict. Nest I will introduce to you the specific steps for how are fire bricks made.

Fire Bricks Raw Material

Sintering Fire Brick

Raw Material Preparation

The main raw materials of refractory bricks include kaolin, quartz sand, expansion agents, binders, etc. First, refractory firebricks suppliers need to prepare these raw materials and conduct strict quality control. Therefore, this ensures that raw materials meet production requirements.

Raw Material Mixing

The prepared raw materials are mixed in specific recipe proportions. The purpose of mixing is to distribute the various raw materials evenly. Then, we keep the chemical composition and physical properties of the final product up to standard.

Mortar Preparation

The mixed raw materials are prepared by adding water to the mortar. What’s more, the quality and proportion of mortar have a significant impact on the performance of the final product. Therefore, as a firebrick and refractory company, Kerui will strictly control parameters such as moisture content, mixing time and mixing speed.


In this refractory bricks manufacturing process,  after the mortar is prepared, it enters how to make firebricks forming. So, common forming methods include extrusion and compression molding. What’s more, the Kerui factory uses press molding. Press molding is to put mortar into a mold and press it into shape through pressure.


We need to dry the formed refractory bricks to remove the moisture in the mortar. Drying is preparation for sintering. Therefore, fire bricks manufacturers need to dry it to remove the moisture. This can prevent the fire bricks from cracking due to sudden temperature rise during the sintering process. This step usually uses drying equipment for rapid drying.


The dried refractory bricks need to be sintered to improve their physical strength and fire resistance. Generally, the sintering process of fire bricks manufacturing usually takes place at high temperatures. Besides, this causes the particles in the bricks to bond with each other, forming a dense structure.

Quality Inspection

Like checking lightweight insulating fire bricks,  after production is completed, refractory bricks require quality inspection. We test the size, appearance, physical properties and chemical composition of the firebrick refractory. So the fire brick company of Kerui can ensure that products meet standard requirements.

Package and Storage

Refractory bricks of acceptable quality will be packaged and properly stored. Generally speaking, common packaging methods include wrapping in plastic film or stacking bricks on wooden pallets. During storage, care should be taken to prevent the bricks from getting wet, exposed to direct sunlight, or mechanically squeezed.

Target Industries of Fire Bricks Manufacturers

Steel Industry

Generally speaking, during the high-temperature smelting process, the steel industry requires a large number of fitting fire bricks as lining materials for high-temperature furnaces. In addition, Kerui refractory bricks can withstand extremely high temperatures and chemical attacks during the steel smelting process.

Ceramic Industry

In the ceramic production process, high-temperature kilns are required for sintering and drying processes. Refractory bricks serve as the lining material for kilns and can withstand high temperatures and chemical attacks. Therefore, it ensures the stable operation of the kiln and firebrick refractory quality.

Chemical Industry

The demand for making fire bricks in the chemical industry is also very large. Refractory bricks and aluminate cement are used as lining materials for equipment such as reactors, storage tanks and pipelines to withstand high temperatures and corrosion. Therefore, it maintains the stability and security of your device.

Power Industry

The power industry requires the use of large boilers and combustion equipment. We make fire bricks cut to size as lining materials inside boilers and can withstand thermal stress. At the same time, it can also resist the erosion of coal ash. The use of fitting fire bricks can improve the efficiency and life of the boiler.

Cement Industry

Cement production requires the use of high-temperature equipment such as rotary kilns for calcination and sintering. Firebrick refractory serves as lining material and can withstand high temperatures and chemical attacks. This ensures the stable operation of cement production equipment and product quality.

Metallurgical Industry

In the metallurgical process, high-temperature furnaces are required for processes such as metal smelting and refining. As the lining material of furnaces, high alumina fire bricks can withstand extremely high temperatures and corrosive gas erosion. This increases the service life of metallurgical equipment.
