Excellent Features of Kerui Refractory Fire Brick for Sale

Environmentally Friendly

From the selection of raw materials, production of refractory fire bricks to the final delivery, Kerui insists strict environmental management system. At the factory, Kerui installed epoxy flooring to protecting the ground. Besides, this also maintains a healthy working environment for workers. During the production process, Kerui uses desulfurization and denitrification equipment to purify the production environment of refractory firebricks.

High Refractoriness

Kerui improves the refractoriness through high-purity raw materials as well as advanced production equipment. Now Kerui refractory fire brick can withstand about 1790℃(3254℉). This is an important feature in high temperature applications. Moreover, this is an important feature that distinguishes Kerui Refractory brick from other types of bricks. If you need a kind of high heat brick for your business, Kerui Refractory can provide suitable products.

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. Therefore, choosing refractory bricks 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. Overall, Kerui can provide reliable services to customers in high temperature industries.

Selection of Raw Materials Batching Molding Drying Sintering Package
  • 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. Therefore, Kerui has a raw material advantage. Not only can we obtain high-quality raw materials efficiently, but we can also control raw material costs. Moreover, these high-purity minerals contribute to the high quality of the final product.

  • 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. 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.

  • 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.

  • 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 in high-temperature environments. Refractory bricks are often made from 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.
