Product Name: High-Carbon Steel base Adamite Roll Ring Model NO.: AD roll ring Certification: ISO Type: Steel Rolling Equipment Casting Method: Centrifugal Cast Shall Hardness: 40-60 Hsd Core Hardness: 38-48 Hsd Weight: ?5tons Size: as Per Drawing Trademark: CAMET Transport Package: Wood Box Specification: ISO Origin: China Product Description High-carbon steel base adamite roll ringDescriptionThe carbon content of steel base adamite is between steel and iron. The material holds the strength and toughness of steel rolls, and meanwhile possesses the high hardness and good wear-resistance as the iron roll. In order to improve the wear-resisitance, the content of carbon is controlled nearly the same as iron. The microstructure of the shell of high-carbon steel base adamite ring consists of matrix and carbides. It features the tiny hardness fall in the working layer and even wear-resistance, ensuring the consistency in dimension when rolling large-section pieces. Graphite steel is used as the core material due to its high strength meeting the requirements of big rolling force.Mechanical propertiesHardness of shellHSD40-60Hardness of coreHSD38-48Tensile Strength of core≥450MPaChemical analysisGradeCSiMnNiCrMoAD1801.7/1.90.3/0.80.6/1.10.5/2.00.8/1.50.2/0.6AD1901.8/2.00.3/0.80.8/1.21.0/2.01.5/3.50.2/0.6AD2001.9/2.10.3/0.80.8/1.20.6/2.50.6/2.00.3/0.8ApplicationsMainly used for cantilever and edging stand or plane-barrelled roll of H-beam mills.
