Good Properties of Kerui Fire Resistant Brick for Sale

Heat Resistance

Kerui fire resistant brick is made of raw materials with high purity, which results in better heat resistance. After thousands of tests and experiments, Kerui fire rated brick can withstand extreme high temperature up to 1700℃ (3092℉). With integrity under high temperatures, Kerui fire resistant brick for sale can be use in various industries. Moreover, this brick has longer service life.

Chemical Resistance

When building glass furnaces, environmental protection equipment, chemical furnaces or other furnaces that are severely eroded by chemical solutions, customers tend to choose chemically resistant bricks like fused cast AZS block. Kerui enhances corrosion resistance by improving the chemical composition and structure of refractory bricks, thereby prolonging the service life of the kiln.

Thermal Shock Resistance

Thermal shock resistance means that the refractory brick inside the kiln can still maintain stability in the face of high temperature shock. Kerui magnesia-chrome brick and magnesia-calcium brick series have good thermal shock resistance. Kerui has professional testing equipment for physical and chemical properties, and we can provide authoritative testing reports.

Slag Resistance

The high density and low porosity of Kerui fire resistant bricks bring excellent slag resistance. This brick can resist slag, dust, metal solution, gaseous substances, etc. of metallurgical furnaces. According to the specific conditions of the kiln, Kerui can produce refractory materials with similar chemical composition to the slag to reduce the reaction intensity.

Wear Resistance

Kerui fire resistant brick has excellent wear resistance to face continuous change in high temperature kilns. In order to prolong the service life of refractory bricks and kilns, the wear resistance must be improved. Kerui creates high-density refractory bricks through reasonable particle size composition and advanced preparation technology.

Pressure Resistance

Pressure resistance refers to the ultimate load that refractory bricks can bear per unit area at a certain temperature. This feature is of great significance to the storage and masonry of refractory bricks. Customers usually stack refractory bricks for storage. Kerui refractory bricks with high pressure strength will not affect subsequent use after being stored for a long time.

Advanced Manufacturing Process of Kerui Fire Resistant Brick

Accurate Ratio on Raw Materials

Kerui implements a strict raw material inspection system to ensure the quality and consistency of the materials used. This helps in maintaining the desired properties of the fire-resistant bricks. Additionally, an automated batching system is employed to precisely control the ingredient proportions, ensuring accurate and consistent mixing of the raw materials.

Precise Molding

More than 20 sets of high-tonnage press machines are utilized to exert significant pressure on the brick pulp, which results in precise shaping and compacting of the fire-resistant bricks. After molding, the bricks undergo a secondary inspection to ensure they meet the required standards and specifications before further processing.

Efficient Drying and Sintering

Kerui factory is equipped with 2 tunnel kilns with 168 meters. There are also PLC systems to accurately control and monitor real-time temperature and position during the drying and sintering processes. This ensures optimal conditions for the fire burnt bricks to achieve the desired strength and properties.

Careful Check and Packaging

A dedicated quality control department conducts regular inspections and sampling to ensure the overall quality and consistency of the fire-resistant bricks. The bricks are carefully checked for any defects or deviations from the specifications. Only qualified fire resistant bricks are packaged according to customer specifications. Kerui also offers customizes packaging solutions.
