- 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.
- 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.
- 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. Moreover, the pass rate of Kerui finished products is as high as 98%!
