Product description
Ultra low cement castable refractory are formulated with Shanxi bauxite and locally selected bauxite clinker as the main raw materials, pure calcium aluminate high alumina cement as the binding agent, and a variety of improvements. It has high density and high operating temperature. , high purity, good thermal stability and other characteristics. Mainly used in working linings of heating furnaces, boilers, melting furnaces,etc.
Advantages of ultra low cement castable refractory
Compared with ordinary refractory castables, the ultra low cement castable refractory 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.
CH Refractories factory advantages:
The unshaped refractory materials produced by our company are produced through various manufacturing processes such as raw material particle processing, raw material powdering, and comprehensive mixing of raw materials. Some products need to be trapped in advance, mixed with binders, or prefabricated in advance. Amorphous refractory materials, such as refractory castables, refractory plastics, refractory spray coatings, refractory coating materials, and prefabricated parts are used in domestic and foreign kiln manufacturers and high-temperature kilns.
