    Good Chemical Resistance

    When using the fire brick refractory in industrial kilns and furnaces, it may encounter chemical corrosion. Choosing the right refractory bricks is also very important. For example, when faced with acid solution erosion in a glass kiln, customers may need to choose silicon-aluminum refractory bricks. In order to further enhance the correspondence, the best choice for customers is the harder and more stable AZS bricks. You can contact Kerui to find a suitable brick.

    Strong Mechanical Strength

    The mechanical strength of refractory bricks is important in maintaining the stability of kiln operation. You should know that when customers lay refractory bricks on the furnace wall, furnace roof or other parts, huge pressure will be generated. Once the refractory bricks crack in a certain part, other parts are likely to face instability. As a professional refractory fire brick supplier, Kerui offers products with higher mechanical strength can help maintain safe operation.

    Thermal Shock Resistance

    High-temperature kilns often need to face rapid heating or cooling. Besides, the refractory bricks provided by Kerui have strong thermal shock resistance, maintaining their structural integrity and reducing the spread of thermal stress in high-temperature structures. Accordingly, Kerui high temp fire bricks have uniform thermal expansion, which ensures that the entire kiln expands or contracts evenly, thereby avoiding cracking of the bricks.

    Long Service Life

    Based on the above excellent characteristics, Kerui refractory bricks have a longer service life than other companies’ products. Therefore, customers can effectively extend the service life of the kiln by adopting this product. Beyond this, Kerui provides high-quality products and professional construction guidance to support your project and extend kiln and product life.

    Kerui Advanced Production of Refractory Fire Bric

    Step1. Selection of Raw Materials
    • Partitioned storage;
    • Strict quality control;
    • Precise particle size of raw materials;

    As an original refractory brick supplier in China, Kerui is surrounded by rich mineral resources. Moreover, China is the one of the largest refractory raw materials supplier in the world. Therefore, Kerui has a raw material advantage. Not only can we obtain high-quality raw materials efficiently, but we can also control low raw material costs. Moreover, these high-purity minerals contribute to the high quality and reasonable price of the best fire bricks.

    Step2. Batching
    • Fully automatic batching system;
    • Three-dimensional workshop;
    • 2 PLC systems;

    Kerui applies a fully automatic batching system to ensure the accuracy of the batching ratio to the greatest extent and reduce human intervention. Accordingly, the performance of the final product is guaranteed. Additionally, at this step, customers can customize the chemical composition, performance, etc. of the refractory bricks. Besides, the mixer will stir and mix the raw materials for more than 5 minutes. Therefore, the aggregate of refractory bricks is a uniform and fine powder.

    Step3. Molding
    • 20 sets of press machines;
    • Precise sizes of refractory bricks;
    • Quality control of molded bricks;

    The mixed raw materials will be sent to the brick press. There are more than 20 high-tonnage brick presses here, which can determine brick types efficiently and accurately. Besides, here you can customize the shape of clay refractory bricks. In addition, the Kerui quality inspection system will weigh the formed brick blanks twice. While only those that pass Kerui quality inspection will be sent to the drying system. Therefore, customers had better choose a reliable firebrick and refractory company to ensure the quality.

    Step4. Drying
    • Heat exchange system;
    • Uniform temperature;
    • Assurance;

    Drying is an important step to prevent the cracking of refractory bricks. Besides, the drying process strengthens the internal structure of the refractory bricks, which increases strength and durability. This helps ensure that the bricks can withstand pressure and thermal stress. Refractory fire brick manufacturers often use raw materials that contain water, such as clay and minerals. If these water-containing raw materials suddenly evaporate at high temperatures, it may cause cracking and destroy the overall structure.

    Step5. Sintering
    • 2*168m tunnel kilns;
    • PCL control;
    • Environmental Production;

    Kerui has 2*168m tunnel kilns, which can maintain uniform sintering temperatures and higher production efficiency. In addition, this can keep the color of refractory bricks produced in the same batch uniform. Moreover, Kerui uses a PLC system to control the temperature and positioning of each kiln car. In this process, Kerui uses desulfurization and denitrification equipment to purify the production environment. It’s important for the fire brick and refractory company to control the presice temperature.

    Step6. Package
    • Customized package;
    • At least 3 layers of protection;
    • On-time delivery;

    Before the product is shipped, Kerui quality inspection department will inspect various indicators of the finished product again.
