Product description
Compared with ordinary refractory castables, the low-cement castable series has many excellent properties. It is a high-tech refractory material developed on ordinary castables using the principles of rheology, closest packing theory and ultra-fine powder technology. It has the characteristics of low porosity, small pore size, high density, good volume stability, high strength and small amount of water added.
Applications of lc 70 castable:
lc 70 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.
