Light weight castables can be divided into the following types:
1, light mullite castable
Light mullite castable is a kind of thermal insulation material with light mullite as the main raw material. It is usually composed of lightweight mullite particles, aluminate cement and other additives, and is applied to the thermal insulation layer of industrial kilns by mixing and pouring.
2, perlite light castable
Perlite refractory castable is generally suitable for 600 ~ 900ºC temperature environment. The use of Portland cement as bonding agent fully meets the requirements of kiln use. When preparing, wet the perlite first and then mix the material, stir evenly and add water to wet mix. When forming, vibration time should be controlled to ensure bulk density. Natural curing is carried out for 3 days after forming, and wet curing can be carried out when the temperature is higher than 25ºC.
3, porous clinker light castable
Porous clinker light castable is mainly divided into clay and high aluminum two types, its bulk density between 1.1~1.8g/cm3, the use of temperature can reach 1300ºC and 1400ºC. When preparing this type of refractory castable, it is necessary to weigh and mix the raw materials according to the specific mix ratio requirements, and then use vibration or manual vibration molding, remove the mold after natural maintenance for one day, and continue to maintain for two days. There is no need for drenching during curing, as the amount of mixing water is sufficient to meet the hydration needs of the cement.
4. Ceramisite lightweight castable
Ceramisite lightweight castable is a kind of refractory material prepared by high quality shale ceramisite, refractory powder, binder and admixture. It is characterized by low volume density, high strength, small line variation and low thermal conductivity. The castable is suitable for medium and low temperature thermal equipment, such as petrochemical pipe heating furnace, as a good lining material.
5, vermiculite light castable
The use temperature of vermiculite refractory castable is 600 ~ 800ºC. It is characterized by good adiabatic performanceWhy choose us?
