Carbon block is using in metallurgy industry as a kind of carbon refractory. It can be divided into 3 items: blast furnaces carbon block electric furnace carbon block and aluminium electrolysis cell carbon block. Our products mainly electric furnace carbon block with thermal shock resistance high elevated temperature strength low coefficient of thermal expansion and ability to anti-corrosion. It is the essential Lining masonry material for calcium carbide furnace and ferroalloy furnace.such as Ferro Silicon furnace silicon metal furnacephosphorus furnace silicon manganese furnace calcium silicon furnace tin furnace etc.. 1.Prebaked carbon block：Ash%<8.0、V.M%<2、F.C%>90、compressive strengthMpa） >36、porosity%<20 、bulk density g/cm3 >1.52 2.self baking carbon block：Ash（%）≤6、Carbon（%）≥93、Residual contractionDegrees 800℃（%）≤0.05、Compressive StrengthMpa）≥30、Volume density（g/cm3)≥1.52、apparent porosity（%）20 3.Half of graphite carbon block：Ash（%）≥8、True density（g/cm3)≥1.90、Compression strength Mpa）≥38、Volume density（g/cm3)≥1.55、Breaking strengthMpa）≥9.8、Porosity （%）≤18 4.Specification:400*400*(400-1800mm)400*500*(400-2500mm)600*650*(600-2000mm) 800*800*(800-1900mm) The length is according to the customer's requirement can process various models according to customer requirements specification of special carbon block furnace mouth carbon block. 5.Packaging:Ordinary wooden pallet or fumigation tray steel belt packing. 6.Terms of payment:cash, letter of credit.
