Graphite Cast Steel Rolls

Graphite Cast Steel RollsAll Kaida Rolls are certified with ISO9001:2008. The characteristics of graphite cast steel rolls are similar to that of adamite rolls,Website:http://www.kdroll.com,the main character is that it contains a small amount of fine graphite in its microstructure,which will increase its resistance to fire crack and prevent oxidized scales from adhering. They are suitable for blooming and roughing stands.The properties of graphite steel rolls are similar to adamite rolls, matrix microstructure are also similar to each other. Due to the great thermal conductivity of graphite, thermal stress caused by rolling process can be greatly reduced. In the meantime, thanks to free point graphite, better fire crack resistance can be achieved. Normal hardness of graphite steel is HS 35~60. Chemical Composition %SymbolCSiMnCrNiMoGS1401.30-1.501.20-1.600.50-1.000.40-1.000.50-1.300.20-0.60GS1601.50-1.701.00-1.700.60-1.100.60-1.000.40-1.100.20-0.50GS1901.80-2.000.80-1.500.60-1.000.50-2.000.60-2.200.20-0.80Prosperities&ApplicationSymbolHardnessHSTensile StrengthMPaElongation %ApplicationGS14036-46≥540≥1.0Roughing stands of small and medium section mills, bar and wire mills and hot strip mills, roll sleeves for universal millsGS16040-60≥500≥1.0GS19055-65≥450≥0.4
