Product description
Low-cement castables are castables with low cement content. They are characterized by low cement dosage, low calcium content, low porosity, and strong erosion resistance.
The most commonly used low-cement castable is aluminum silicate, which is a high-aluminum low-cement castable. The cement content of high-aluminum low-cement castable is 6%. If the cement content is 1%, it is an ultra-low cement castable.
Application of ultra low cement castable
Ultra low cement castable are suitable for lining heating furnaces, various heat treatment furnaces, electric furnace covers, shaft kilns, rotary kilns, blast furnace tapholes, ladles, ladles, etc.; self-flowing low-cement castables are suitable for linings with metal anchors. Linings of high-temperature refractory components, such as water-cooled tube linings of heating furnaces, integral spray gun linings for spray metallurgy, impregnated tube linings of RH and DH vacuum degassing devices, ladle gas supply components and petrochemical catalytic cracking reactors High-temperature wear-resistant linings, etc.; are mostly used in construction of parts with complex structures, which can greatly improve the overall use effect.
