Strategies to extend the life of refractory bricks include correct material selection, scientific construction, reasonable use and regular maintenance. The following is a detailed introduction:

1. Material selection
Choose high-quality materials: High-quality refractory materials have higher resistance to high temperature, thermal shock and corrosion, such as high-alumina bricks, silicon bricks, silicon carbide bricks, etc.
Choose materials according to working conditions: Different working environments have different requirements for refractory bricks. For example, high-alumina bricks or mullite bricks are used in high-temperature furnaces, while silicon bricks are used in environments with acidic atmospheres.
Consider the thermal conductivity of the material: Materials with good thermal conductivity can better dissipate heat and reduce thermal stress, thereby extending the service life of refractory bricks.
2. Scientific construction
Construct strictly in accordance with the design drawings: The construction process should be strictly carried out in accordance with the design drawings to ensure the correct arrangement and close contact of the refractory bricks.
Use suitable bonding materials: Use refractory mud that matches the refractory bricks to ensure the sealing and firmness of the brick joints.
Prevent construction defects: Avoid problems such as excessive brick joints, misalignment, hollowing, etc., and carefully check and correct during construction.
3. Reasonable use
Control the temperature gradient: During the heating and cooling process, the temperature change rate should be controlled to avoid excessive thermal stress of refractory bricks due to rapid temperature changes.
Avoid excessive use: Reasonably arrange the use time of the furnace, avoid long-term high-load operation, and reduce the thermal fatigue of refractory bricks.
Regular shutdown and maintenance: Regularly shut down the furnace for maintenance, check the condition of refractory bricks, and replace damaged bricks in time.
4. Regular maintenance
Regular inspection: Regularly check the surface and interior of refractory bricks, and deal with cracks, peeling and other problems in time.
Timely repair: Small damage should be repaired in time to prevent further expansion. Refractory repair agent or refractory coating can be used for repair.
Take protective measures: During use, pay attention to protect refractory bricks from mechanical damage and chemical erosion. For example, avoid heavy objects hitting refractory bricks and prevent corrosive gases and liquids from contacting the brick surface.
5. Comprehensive management
Establish maintenance files: Establish refractory brick use and maintenance files to record the use and maintenance history of refractory bricks for easy analysis and management.
Train operators: Provide professional training for operators to enable them to master the correct operation and maintenance methods and reduce the impact of human factors on the life of refractory bricks.
Introduce new technologies: Keep paying attention to new technologies and processes in the field of refractory materials, and introduce suitable technologies in a timely manner to improve the performance and service life of refractory bricks.
Conclusion
Refractory bricks are an indispensable and important material in high-temperature industries, and their service life is directly related to production efficiency and cost. By selecting high-quality materials, scientific construction, reasonable use and regular maintenance, the life of refractory bricks can be significantly extended, production costs can be reduced, and economic benefits can be improved. At the same time, comprehensive management and operator training are also important guarantees to ensure the long-term and stable operation of refractory bricks. In short, extending the life of refractory bricks is a systematic project that requires comprehensive consideration and implementation from multiple aspects.
