According to the supplier of precast concrete components, precast is a low-temperature heat treatment, which is a unique technology in refractory lining technology.

The prefabricated parts can improve the performance of refractory lining, reduce the consumption of refractory materials, the quality is stable and the performance is reliable. The prefabricated castable made by special process can improve the mechanical properties of castable, inhibit the occurrence of cracks or limit its expansion when cracks are formed.

The preform is made into a certain shape according to the process position and needs, and heat treatment is carried out according to its working conditions after demoulding. The preform has better application performance than the castable.

More prominently:

(1) The compressive strength of prefabricated parts is 2 times higher than that of refractory castables.

(2) The thermal shock resistance of the preform is 2-3 times higher than that of the castable.

(3) The wear resistance of the preform is twice that of the castable of the same material.

(4) Save construction time: No on-site pouring, erection and disassembly of molds and construction tools are required. The molded parts only need to be assembled and installed on site, which is convenient and fast, greatly reduces the on-site construction time, stable in quality, and is not restricted by on-site construction conditions and human factors.

(5) Save curing and baking time: The supplier completed all the steps of pouring, curing, drying and baking in advance at the time of delivery, saving a lot of curing and baking time, and effectively solving the problem of cracking of the castable due to rapid fire and temperature rise on site.

(6) Cement kilns in different countries and seasons all over the world are quite different. When the castable for cement kiln is constructed on site, the high temperature can reach 43~48 in some countries, and the low temperature can reach below minus 30 in some countries. The temperature difference between the south and the north of China is also large. The construction of castable is limited by the ambient temperature. When the temperature fluctuates too much, appropriate manual control measures should be taken to ensure the normal construction and quality, the preforms can be installed in any environment.

(7) It is very convenient to replace in actual production. If the prefabricated component is damaged, the damaged part can be directly replaced, and the replacement can be completed in a short time, realizing the desire of immediate replacement.

(8) The storage period of castable is short, and it is generally half a year under dry conditions, while the storage period of prefabricated components is greatly extended, which can be as long as several years.

(9) The performance of refractory castable is greatly affected by on-site construction conditions and human factors, such as excessive water addition, which increases the porosity, reduces the strength of false vibration and affects the service life, while the expected service life of prefabricated parts is increased by 2-3 times, saving investment, energy saving and environmental protection.

　　Precast concrete components supplierXiao Bian learned that many refractory manufacturers, in combination with the parts and construction conditions of castables for cement kilns, prefabricated the gates of the tertiary air ducts, the lower wall of the grate cooler and other parts with castables in advance, baked at low temperature to remove the crystalline moisture in the prefabricated parts of the castables, and then sent them to the site for direct installation and production, thus greatly improving the service life.

Well, today's concrete precast component supplier editor will talk about it first. Thank you for watching.
