Specifications
Refractory castable manufacturer Low cement refractory castable Type:A-45,A-60,A-70,A-80. Density:2.3-3g/cm3 AL2O3:45-90%
The picture above shows low cement refractory castable in woven bag .
Yuntai Furnace is the specialized manufacturer and exporter of refracotry and insulation material in north of China. Our products mainly include refractory castable, refractory brick, insulating brick. For refractory castable, Double Egert has the production capacity 500tons per month, primarily export to USA, AUSTRALIA, RUSSIA, JAPAN, GREECE etc.
characteristics:
1. The dosage of cement is low, the content of calcium only accounts for 1/4-1/3 of common Refractory Castable2. Wter consumption rate during the construction is almost 1/2 or 1/3 of the common Refractory Castable, so the Low Cement Refractory Castable has high density and low porosity.3. High normal temperature cure property, intensity will be increased after medium temperature and high temperature. Three or five times more than common Refractory Castable.4. Good volume stability under high temperature.
Application:
Material for metallurgy, petroleum, chemical and other industries kilnsPart of refining installation, like ladle coverInsert for roof of the kiln
