Advantages of Refractory Prefabricated Parts

》There is no need for on-site pouring construction or formwork pouring, which reduces labor costs and material costs.

 

》Heat-resistant anchors are not required, eliminating the material and construction costs of anchors.

 

》The pouring, curing, drying, and baking steps of prefabricated parts have been completed when delivered, saving a lot of construction time.

 

》It is not restricted by environmental and climatic conditions, which solves the problem that castable materials cannot be constructed on-site under natural conditions during hot summer and severe winter.

 

》It can be made into various special products with different sizes and shapes. Such as grate cooler low wall, tertiary air duct elbow, lifting gate valve, kiln tail smoke chamber, coal injection pipe, kiln mouth, and other refractory materials.

 

》Maintenance is easy to replace, has little waste loss, and saves labor and time. Corundum, fused mullite, special grade bauxite aggregate, and special wear-resistant materials are added to the material, and a certain proportion of special additives are added. Vibration forming.

Refractory prefabricated parts are to divide the pre-constructed parts into small pieces in advance, and design a suitable shape, and then make a mold according to the shape, and then pour it in the factory, after curing, and baking, it is transported to the site for construction and installation.

 

Most of the parts used in refractory prefabricated parts are in special parts under severe environments such as high temperature, cement clinker erosion, abrasion, rapid cooling and rapid heating, which are prone to mechanical deformation and require good erosion resistance, good wear resistance and high temperature gas resistance. Washability and excellent thermal shock stability.

 

The refractory materials in the key parts of the cement kiln require high construction quality during the construction process. During the maintenance period of the cement kiln, the general construction period is short, and the construction quality of on-site pouring is difficult to guarantee. The quality of the construction quality has a great impact on the service life of the refractory materials. Impact. The increase of water addition will increase the porosity of the castable, reduce the strength, and seriously affect the wear resistance of the castable. After the construction of the castable is completed, there must be a certain curing time. After the curing is completed, it must be baked, otherwise it is easy to burst.

 

Since the production process of refractory prefabricated parts is carried out in the production enterprise, it can overcome the adverse effects caused by the tight construction time on site, environmental seasonal temperature changes, and on-site construction management. The quality problems caused by non-standard construction make the performance of refractory materials fully exerted. After installation, it is directly ignited and used, which shortens the maintenance time and can create good economic benefits.

 

Attention To Of Refractory Prefabricated Parts
 

Storage and transportation. During storage and transportation, prefabricated parts should be protected from moisture, heat, and external force damage. It is recommended to store prefabricated parts in a dry, ventilated, and cool warehouse. And pay attention to reasonable stacking to avoid extrusion and deformation.

 

Install. When installing refractory prefabricated parts, design requirements, and construction specifications should be strictly followed. For different types of prefabricated parts, corresponding installation methods and connection methods need to be adopted. During the installation process, it should be ensured that the position of the prefabricated parts is accurate and that good connection and sealing properties are maintained.

 

Seam treatment. Seams between precast parts should be kept clean and tight to prevent heat loss and the penetration of aggressive gases. Depending on the actual working conditions and precast material, appropriate filling materials can be used for joint treatment. Such as refractory mud, refractory fiber, etc.

 

Temperature control. During the initial heating and operation of the furnace, the heating rate and temperature should be strictly controlled. To prevent the refractory prefabricated parts from being damaged due to thermal stress caused by excessive heating. At the same time, regularly check the use of prefabricated parts to detect and deal with potential problems in a timely manner.

 

Maintenance and overhaul. During use, the refractory prefabricated parts should be inspected and maintained regularly. If damage, cracks, and other problems are found, they should be repaired or replaced in time. For prefabricated parts with a long service life, timely cleaning and maintenance can be carried out to extend their service life.

 

With proper selection, installation, and maintenance, refractory prefabricated components can provide efficient and stable performance for industrial furnaces. Save construction time and cost at the same time. In the continuously developing industrial field, the application of refractory prefabricated parts will continue to expand to meet the needs of various working conditions and environments.

 

 

Process of Refractory Prefabricated Parts

Batching process is the foundation for ensuring product quality. Raw material ratios must be scientifically designed based on service conditions and performance requirements. Different particle size aggregates are mixed in certain proportions. This forms reasonable particle gradation and ensures good density and strength.

 

Forming process uses pressure forming or plastic forming methods. Pressure forming uses mechanical pressure to press the mixture into shape. It is suitable for most shaped products.

 

Plastic forming adds appropriate binders and moisture to the mixture. It uses extrusion or casting to form shapes. It is suitable for products with complex shapes.

 

Drying process removes free moisture from products. This prevents cracking during firing due to rapid moisture evaporation. Drying temperature is usually controlled at 110-150°C. Drying time depends on product thickness and moisture content.

 

Sintering process is the key step for products to obtain final performance. Sintering temperature usually ranges from 1400-1700°C. High temperature causes physical and chemical reactions in raw materials. This forms stable mineral phases and dense microstructures.

FAQ

 

Q: What are the benefits of refractory bricks?

A: Refractory materials are beneficial for fighting physical loads, preventing vessel wall erosion, protecting against corrosion, and providing thermal insulation. They also serve as a solid thermal barrier between the wall of a container vessel and a hot medium.

Q: What is precast refractory?

A: Precast refractory shapes are prefabricated forms made from refractory materials that are designed to be used in high-temperature applications such as furnaces, kilns, and incinerators. They are manufactured in a controlled environment, typically in a factory, and then transported to the installation site for use.

Q: What's the difference between prefabricated and precast?

A: Precast construction involves casting concrete in a reusable mold or form at the factory and then transporting it to the construction site for assembly. On the other hand, prefabricated construction refers to assembling building components off-site and then transporting them to the construction site for installation.

Q: How long does refractory cement last?

A: Depending on the composition of the material, most refractory materials have a shelf life ranging from six to twelve months. The shelf life is due to most monolithic materials containing cement.

Q: How thick should my refractory cement be?

A: 1 1/2 to 2 inches thick
Good for applications well over 2500°F. Castable refractory cement should be cast no thinner than 1 1/2 to 2 inches thick.
