In modern industry, the application of refractory materials is crucial. Especially in high temperature and chemically corrosive environments. As common refractory materials, refractory prefabricated parts and refractory bricks have significant differences in production processes. Therefore, this directly affects their performance and applicability in their respective application scenarios.
Differences in Production Processes
Raw Material Selection and Preparation
Refractory bricks: Refractory bricks usually use natural mineral materials such as high-alumina bauxite and clay as the main raw materials.
Refractory precast: The raw material selection of refractory prefabricated parts is more diverse. This includes not only refractory brick particles and high-alumina bauxite, but also silicate fibers and refractory cement.
Molding Process
Refractory bricks: Refractory bricks are usually formed by extrusion molding and compression molding. This ensures the dimensional accuracy and surface quality of the finished product.
Refractory precast: Kerui can use high-efficiency processes such as extrusion molding, compression molding and grouting molding to form them. Therefore, we can mass-produce precast refractory that meet complex design requirements.
Sintering and Hardening Process
Refractory bricks: After forming, refractory bricks usually need to be sintered at high temperature. This process can make their structure more dense and strong and improve their fire resistance and mechanical strength.
Refractory precast: We have chemical bonding or heat hardening methods. This method not only saves energy, but also adapts to a wider range of design requirements and material combinations.
Differences in Performance and Application
Application Scope and Design Flexibility
Refractory bricks: Due to the limitations of the molding process, refractory bricks are relatively fixed in shape and size. They are suitable for some traditional industrial furnace and furnace lining applications.
Refractory precast: The design flexibility of good refractory prefabricated parts is extremely high. We can customize them according to the shape and size requirements of specific industrial equipment and furnaces. This makes them more suitable for complex industrial applications. Such as high-temperature kilns, furnace linings, flues and pipes.
Refractory Performance and Durability
Refractory bricks: Their structure is relatively simple and dense. Therefore, refractory bricks generally have high refractoriness and mechanical strength. They are suitable for long-term and stable high-temperature use environments.
Refractory precast: The refractoriness and durability of refractory prefabricated parts depend on the specific material formula and process. They can adjust the material combination according to demand to achieve better heat resistance, chemical corrosion resistance and mechanical strength.
