Seamless Tube Rolling Mill Roll

Product Name: Seamless Tube Rolling Mill Roll Model NO.: Seamless tube rolling mill roll Certification: ISO Type: Steel Rolling Equipment Condition: New Customized: Customized Casting Method: Centrifugal and Static Cast Barrel Hardness: 45-72hsd Core Hardness: 33-55hsd Weight: 0.1-20tons Trademark: CAMET Transport Package: Steel Rack Specification: ISO Origin: China Product Description Seamless tube rolling mill rollPropertiesThanks to its higher content of Ni and Mo alloys, pearlite, basinite and martensite matrixes with excellent performance are produced. The graphite si spherical form, demonstraing good heat transfer property and high tensile strength. Through changing the struture into basinite of marensite matrix, chemical compostion of needly-like spherical iron of heat treatment, a dense reticular primary cementite with high wear-resistance is producedChemical Analysis Designation of rollsCSiMnPSNiCrMoMgCrMo semi-chilled SG cast iron rolls2.9/3.60.8/2.50.4/1.2≤0.25≤0.030.2/0.60.2/0.6>0.04CrMo indefinite chilled SG cast iron rolls2.9/3.60.8/2.50.4/1.2≤0.25≤0.030.2/0.60.2/0.6>0.04NiCrMo indefinite chilled SG cast iron rolls (I)2.9/3.60.8/2.50.4/1.2≤0.25≤0.030.5/1.00.2/0.60.2/0.6>0.04NiCrMo indefinite chilled SG cast iron rolls (II)2.9/3.60.8/2.50.4/1.2≤0.25≤0.031.0/2.00.3/1.20.2/0.8>0.04Pearliticnodularcastironrolls (I)2.9/3.61.4/2.20.4/1.0≤0.15≤0.031.5/2.00.1/0.60.2/0.8>0.04Pearliticnodularcastironrolls (II)2.9/3.61.2/2.00.4/1.0≤0.15≤0.032.0/2.50.2/1.00.2/0.8>0.04Pearliticnodularcastironrolls (III)2.9/3.61.0/2.00.4/1.0≤0.15≤0.032.5/3.00.2/1.20.2/0.8>0.04bainitic nodularcastironrolls (I)2.9/3.61.2/2.20.2/0.8≤0.10≤0.033.0/3.50.2/1.00.5/1.0>0.04bainitic nodularcastironrolls (II)2.9/3.61.2/2.00.2/0.8≤0.10≤0.033.5/4.50.3/1.50.5/1.0>0.04Physical PropertiesDesignation of rollsBarrel hardness (HSD)Neck hardness (HSD)Tensile strength (MPa)CrMo semi-chilled SG cast iron rolls40~5532~50>300CrMo indefinite chilled SG cast iron rolls55~7035~55>300NiCrMo indefinite chilled SG cast iron rolls (I)48~7035~55>320NiCrMo indefinite chilled SG cast iron rolls (II)48~7035~55>320Pearliticnodularcastironrolls (I)45~5535~55>450Pearliticnodularcastironrolls (II)55~6535~55>450Pearliticnodularcastironrolls (III)62~7235~55>450 bainitic nodularcastironrolls (I)55~7832~45>350bainitic nodularcastironrolls (II)60~8032~45>350MicrostructureDesignation of rollsMicrostructureCrMo semi-chilled SG cast iron rollsPearlite + cementite + SG + small percentage fermiteCrMo indefinite chilled SG cast iron rollsPearlite + cementite + SGNiCrMo indefinite chilled SG cast iron rolls (I)Pearlite + cementite + SGNiCrMo indefinite chilled SG cast iron rolls (II)Fine pearlite + cementite + SGPearliticnodularcastironrolls (I)pearlite + cementite + small percentage fermitePearliticnodularcastironrolls (II)pearlite + cementite + small percentage fermitePearliticnodularcastironrolls (III)pearlite + cementite + small percentage fermitebainitic nodularcastironrolls (I)bainite+ cementite + SGbainitic nodularcastironrolls (II)bainite+ cementite + SGApplicationDesignation of rollsApplicationCrMo semi-chilled SG cast iron rollsSection mill, bar mill, roughing stands of wire-rod mill, work roll of rail millCrMo indefinite chilled SG cast iron rollsSection mill, bar mill, intermediate and finishing stands of wire-rod millNiCrMo indefinite chilled SG cast iron rolls (I)Section mill, bar mill, intermediate and finishing stands of wire-rod millNiCrMo indefinite chilled SG cast iron rolls (II)Section mill, bar mill, intermediate and finishing stands of wire-rod millPearliticnodularcastironrolls (I)roughing stands of bar mill and wire-rod millPearliticnodularcastironrolls (II)roughing stands of bar mill and wire-rod millPearliticnodularcastironrolls (III)roughing stands of bar mill and wire-rod millbainitic nodularcastironrolls (I)roughing stands of bar mill and wire-rod millbainitic nodularcastironrolls (II)roughing stands of bar mill and wire-rod mill
