A-55 Low cement refractory castable

The picture above shows low cement refractory castable in woven bag . This type is A-55 with Al2O3 content 55%. The brand of this product is "CCE WOOL", and OEM is also available. Double Egret is the specialized manufacturer and exporter of refracotry and insulation material in north of China. Our products mainly include refractory castable, refractory brick, insulating brick. For refractory castable, Double Egert has the production capacity 500tons per month, primarily export to USA, AUSTRALIA, RUSSIA, JAPAN, GREECE etc. Low Cement Refractory Castable adopts submircon powder technology. Micro powder 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 owns 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.Wter 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. 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 industries kilns Part of refining installation, like ladle cover Insert for roof of the kiln TECH DATA ItemLow Cement Refractory CastableSpecialNo.A-45A-60A-70A-75A-80A-90S-1S-2Dry Density (g/cm3) ≥2.32.52.62.652.732.72.7Chemical (%)Al2O3≥4560707580907575ZrO2------------33(Cr2O3)Modulus of Rupture(Mpa)110oC×24h≥5899101210101500oC×3h≥8(1350oC)10 (1450oC×3h)12151212Compressive Strength(Mpa)110oC×24h≥30404045456045451450oC×3h≥6080808590859090Linear Dimensional Change After Fired (1500oC×3h)%≤±0.5±0.5±0.5±0.5±0.5±0.5±0.5±0.51350oC×3h1450oC×3h1450oC×3h1450oC×3hRefractoriness(oC)≥17101740179017901790179017901790Working Temp(oC)145014501500155016001650
