Refractory Bricks AAA Quality

Place of Origin	China

?Fire bricks?(?chamotte refractory bricks?)are alumina silicate bricks with the refractoriness of SK 32-34 and contain 35-40% alumina. The bricks are made from various raw material s of fire clay, calcined chamotte, soft clay. We manufacture chamotte bricks using thorough quality control. Shapes and properties depend unpon sevice conditions, becuase the bricks have low porosity, high strength, good resistance to thermal spalling and abrasion and to creep, they are applied for the linings of various incinerators, reheating furnaces etc.?ItemSK-34SK-33SK-32Refractoriness(SK)343332Apparent?Porosity(%)232426Bulk?Density(g/cm3)2.202.152.00Cold?Crushing?Strength(MPa)353020Thermal?Linear?Expansion(%)@?1000℃0.60.60.6Permanent?Linear?Change(%)@?1400℃X2hrs±0.3±0.5±0.5Refractoriness?under?Load(℃)@0.2MPa135013001250Chemical?Composition(%)Al2O3403835Fe2O32.02.23.0Main?Applications-Various?Incinerator-Reheating?Furnace-Blast?furnace-Rotary&?Shaft?Kiln-General?Industrial?Funace?etc.Package:?The bricks are always palletized and shrink wrapped, usually 1.2~1.5MT per pallet.Delivery time: within two weeks after receive the depositDelivery port:Qingdao port
