The Character:

Refractory prefabricated parts combine the shape diversity of amorphous products and the superior performance of molded products, which is better than amorphous refractory materials and more flexible than shaped products. The main process includes several processes of mold making - molding - curing - baking - stripping. Its outstanding characteristics include the following aspects.

 

1. Not limited by the shape of the equipment, can make a variety of block shape prefabricated parts inherit the characteristics of amorphous refractory materials can be shaped, and can be made according to the shape of the equipment, so it can meet the use requirements of the specific shape of the cement kiln.

 

2. Superior material performance and longer service life. Because the production process is carried out in the production enterprise, it can overcome the shortcomings such as urgent construction time and rough management, and the performance of refractory materials can be fully played after full maintenance and strict baking. According to relevant reports, the application of amorphous refractories - castable precast blocks in large-scale cement kilns, the compressive strength is about 2 times higher than that of homogeneous castable, and the thermal shock stability is improved by 8 to 10 times.
 

3. Quick installation, save time no need for on-site pouring, no need to support and disassemble the mold, no need for construction machinery, only need to install the combination on site. Convenient and fast, greatly reduce the site construction time, in the delivery of the supplier has been completed in advance of the pouring, maintenance, drying and baking of each link, effectively solve the site in the rush to fire rapid heating caused by the problem of castable burst, convenient for users to use.

 

4. The construction of castable is limited by the ambient temperature. Too high temperature will lead to early solidification of castable, and too low temperature will lead to slow solidification or non-solidification of castable. Therefore, castable construction should choose the season, winter in the north and high temperature in the south are not suitable for castable construction, and forced construction will lead to a decline in refractory performance. The prefabricated parts have no requirements for the environment, are not limited by the ambient temperature, and can be constructed in any seasonal environment with a wider range of use.

 

5. Easy to replace disassembly and storage in the actual production is very convenient to replace, prefabricated block damage can be directly replaced damaged units, completed in a very short time, for cement enterprises to quickly play the production capacity to provide a guarantee. Amorphous refractories usually have a short storage period, only a few months in dry conditions, while prefabricated blocks greatly extend the storage period, which is expected to reach several years.
