Product Name: Composite Rolls for Rod Rolling Steel Model NO.: as the drawing Application: metal Processing Machinery Parts Material: Alloy Customized: Customized Standard: DIN, ASTM, GB Certification: CE, ISO9001 Condition: New Application Range: All Kinds of Mills Trademark: FANGLE Transport Package: Polywood Case with Steel Straps Specification: as the drawing Origin: China Product Description Composite Rolls for rod rolling steelDescriptionThe structure of the composite roll is reliable, easy to assemble and disassemble, high axial pressure and force of rolling enable the rolls to sustain high 3-D stress, mean-while the spacer protects the roll's corner pin, this protecting is the most reasonable working position for high fragile carbide roll ring, make its life longer and unbreakable. Another the carbide roll ring's shape is simple to produce, it's the keyless connection between shaft and carbide roll ring,use the seiten reining to transfer the torque.The application of composite rolls overcome the problem of cast iron rolls such as poor wear resistance, short using life of rolling groove, influence the steel product's to lerance. Increase the labor intensity, restrict rolling mill increasing its working efficiency. The composite rolls' justification range is very small during the rolling process. The total overall reduction of single side is 0.2mm, make sure the wire mill size rib height size stability during whole rolling process, make wire mill kept within the invariant size.Material gradeGradeChemicalcompositionDensityHardness(HRA)TransverseRuptureStrength(SampleB)N/mm²CompressiveStrengthKg/cm³ApplicationCo+Ni%HRADG62513.108025002900For finishing stand, rolling rod steel, wire rod and steel barDG72712.9078.524002700DG82812.8078.523002600DG93012.6577.523002600For finishing stand, rolling rod steel, wire rod and profiled steel.DG9A3012.6579.525502800Application
