Bulk density:2.1--3g/m3
Refractory material
1.Usage: Material for metallurgy, petroleum, chemical and other industries kilns.Part of refining installation, like ladle cover.Insert for roof of the kiln , Furnace of metallurgy industry, heat treatment furnace,Furnace of chemical industry, glass industry and ceramic industryFurnace of incineration of garbage, recirculating fluidized bed furnace
2.Characteristics: adopts submircon powder technology. Micro powder is used as binder, 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, . The dosage of cement is low, the content of calcium only accounts for 1/4-1/3 of common Refractory Castable
. 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 low porosity.
. High normal temperature cure property, intensity will be increased after medium temperature and high temperature. Three or five times more than common Refractory Castable.
. Good volume stability under high temperature
