Leveler рулонах: выравнивание крена / Flattener рулон

Orient is specilized in metallurgical spare parts, possessing spare parts research, development and fabrication. It has full capacity to manufacture shear blades of different materials, Including high-grade alloy tool steel, High speed steel, carbide alloy, Overlay welded steel with different profiles, rectangular, V-shaped, Circular, Curved and section, Metallurgical cold and hot rolling mill rolls, Sendzimir rolls, Slim rolls for different kinds of plate levelling rolls, casting rolls assembly etc.Rough CylindricalΦ65±0.5 Thermal RefiningHB200-250Finish TurningCylindricalΦ57.50+0.2To stress tempering,and straighteningThe Curvature<0.3Coarse grinding cylindricalΦ55±0.1- Φ56.20+0.1, Φ350-0.02-Φ36.2±0.1 Barrel surface hardeningHRC62-64, Depth>3mmGrinding roller bobyΦ54.940+0.02Both sides of the cylindricalΦ350-0.02-Φ35.080+0.02,Φ300-0.02-Φ30.60+0.02CylindricalΦ200-0.02-Φ20.20+0.02,Φ270+0.02- Φ27.50-0.02Plating barrelΦ55.080+0.02Grinding roll neck boby stick to the finished productConcentricity 0.02 Being very small in diameter and longer in length, this is the most difficult item to make amongst all the rolls. Orient is manufacturing the leveler rolls from the route of induction hardening. The minimum diameter leveler roll that Orient is manufacturing is of 20mm dia. Since the application is concerned with finished coils, it is very important that the rolls meet the following requirements: Good surface finish; Minimum variation( cylindricity and ovality) in the roll diameter; Ability to absorb bending forces and retain original shape.The materials of levelling rolls forheavy plate leveller mainly include X40CrMoV51and 56CrNiMoV7 which have been proved withvery good heat-resistantand long life. The materials of levelling rolls for sheet leveller has been used with advanced technology and new materaisl which has been proved with very good wear-resistant and long life.
