Factors Affecting The Service Life Of Refractory Castables

The service life of refractory castables usually affects the life of the entire high-temperature kiln. The longer the service life, the longer the durability of the high-temperature kiln. Therefore, the service life of refractory castables is crucial. So, what are the factors affecting the service life of refractory castables?

1. Reasonable selection: When choosing refractory castables, we must make reasonable choices based on specific use occasions, use media, use temperature, and other factors, such as high temperature, chemical corrosiveness, thermal stability, creep resistance, and other factors. In this way, the refractory castable can resist the erosion of the corresponding medium during use and extend its service life;

2. Construction quality: The construction quality of refractory castables directly affects its service life. If the construction is not standardized and the bonding is not firm, the refractory castable will be easily damaged.

3. Hardening and baking: After the construction of the castable is completed, it must be hardened and dried for a certain period. After the hardening is completed, the refractory castable must be baked. During the baking process, it must be reasonably heated and baked according to the heating curve to avoid rapid cooling and heating to ensure that the castable can be fully solidified.

4. Maintenance: Regular inspection and maintenance are the keys to maintaining the service life of refractory castables. Refractory castables will gradually age, wear, crack, fall off, etc. Timely repair of damaged parts and insulation treatment are effective maintenance methods.

The service life of refractory castables is usually around 3-5 years, depending on the above factors and the quality and material of the refractory castables themselves. Regular inspection, maintenance, and reasonable use can extend the service life of refractory castables.
