Characteristics of Refractory Prefabricated Parts
1:Have require good erosion resistance,
2:Have good wear resistance and high temperature gas resistance.
3:Have washability and excellent thermal shock stability.
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.
