low Cement Refractory Castable (Al2O3:65%)

Zibo ShunzhouRefractory Co., ltd is a specialized manufacturer and supplier of refractory, we can supply many kinds of refractory products, such as high alumina bricks, fireclay bricks, low porosity fireclay bricks, insulating bricks and many kinds of refractory castable, ramming mass etc. We have exported to USA, India, Germany, Canada etc many countries, and they are satisfied with our products. Refractory castable is unshaped refractory material that doesn't need firing and features fluidness after adding water. Mixed by grain, fines and binder in fixed proportion, refractory castable can replace special shaped refractory material. Refractory castable can be used directly without firing, easy to construct, and has ahigh utilization rate and high cold crushing strength. Shunzhou can supply many kinds of refractory castable such as fireclay castable, high alumina castable, mullite castable, low cement refractory castable, Ultra Low Cement Castable,no cement castable,mullite castable and corundum castable, and several refractory mortars. Low cement castable refractory adopts submicron power technology, Micro power is used as anchoring agent, aluminate cement as coagulation accelerator, some antidetonant and water reducer will also be added in during the production of low cement refractory castable, Compared with common refractory castable, low cement refractory castable owes the below Characteristics: 1. The dosage of cement is low, the content of calcium only accounts for 1/4-1/3 of common refractory castable.2. Water 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 lower 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 industrial kilnsPart of refining installation, like ladle coverInsert for roof of the kilnTHE TECH DATA:MaterialLow Cement RefractoryCastableIndexLC-60LC-65LC-70LC-75Al2O3,% ≥60657075B.D.
