Basic Info Model NO. QJ-0.6 Cold Crushing Strength(MPa) More Than 1.5 Thermal Conductivity Less Than 0.21 HS Code 3816000000 Product Description Customer Question & Answer Ask something for more details Product Name: Lightweight insulation refractory castable Product Specification:   Indicator Item No. QJ-1.0 QJ-0.8 QJ-0.6 Application Temperature 800 Chemical Composition Al2O3(%) ≥30 CCS (MPa) ≥3.0 ≥2.5 ≥1.5 Thermal Conductivity W/m.k(350ºC±25ºC) ≤0.5 ≤0.35 ≤0.21 Bulk Density (g/cm3) ≤1.0 ≤0.8 ≤0.6 Product Description: Refractory Castable is a mixture of Calcium Aluminate Cement (Ciment Fondu), and graded refractory aggregates; effectively, it's premixed refractory concrete. Just add water and mix thoroughly, then trowel or pour into place.  Once set, our dense refractory castable has very similar physical characteristics to fire brick. It has almost the same density, thermal conductivity and compressive strength as the fire brick, but it can be poured or trowelled into place, filling awkward gaps that would be very difficult to fill with bricks.  Our refractory castable have the following features:     1 High strength at both high and low temp  2 Excellent thermal insulation properties 3 Thermal shock resistance 4 Good erosion resistance Applications:  Their wide range of applications, according to the conditions of use of the materials used and binder to be selected. Can be directly poured into the use of the lining, but also can be made by pouring or shaking prefabricated block used. Mainly used to build a variety of furnace lining and other overall structure.  For example:   1.Furnaces of metallurgy industry, heat treatment furnace. 2. Furnace of incineration of garbage, recirculating fluidized bed furnace. 3. Furnaces of chemical industry and construction industry. 4. Tundish lining. Package:  30Kgs/Bag, 33Bags/Ton.
