Excellent Structure of Kerui Refractory Castable
Kerui refractory castable for sale is mainly composed of refractory aggregates, binders, admixtures, etc. It is worth mentioning that Kerui Refractory has a technical chief engineer with more than 40 years of experience and a fully automatic batching system. Customers can rest assured that they will get refractory castable that exceed expectations.
Aggregate
Refractory aggregate refers to the high-purity raw materials that are calcined and crushed, and then added to the refractory castable in a certain proportion. According to the conventional proportion of refractory castable, coarse aggregate (5mm-20mm) accounts for about 35%-45%. Fine aggregate (0.15mm-5mm) accounts for about 30%-35%.
Binder
The binder in the refractory castable is expected to have the function of bonding and hardening. Kerui provides high-quality refractory cement (also called high-alumina cement, calcium aluminate cement) to ensure the degree of hardening after drying. In order to reduce thermal expansion changes and volume shrinkage, the amount of refractory cement added is about 10%-25%.
Admixtures
According to customer needs, some refractory castable for sale can also add appropriate amounts of admixtures to improve their performance. For example, adding an appropriate amount of coagulant can increase the hardening speed of the castable. Increasing the content of certain chemical raw materials can extend its service life at high temperatures.
Advantages of Using Refractory Castable Lining
- High Working Temperature;
- Strong Chemical Resistance;
- Rapid Hardening;
- Good Mechanical Strength.
Easy to Use
Refractory castables are relatively simple to apply compared to traditional brick installations. They can be poured, pumped, or shotcreted into place, allowing for efficient and quick lining of complex shapes and structures.
Long Service Life
Properly installed refractory castables can have a prolonged service life, often comparable to or even exceeding that of brick linings. This longevity is crucial in industries where downtime for maintenance is costly and disruptive.
Energy Saving
Refractory castables can contribute to energy savings by improving thermal efficiency. They provide better insulation and reduce heat loss compared to older linings, thereby optimizing the energy consumption of industrial processes.
