High Strength Output: increases rebar strength up to 550 MPa2. Wide Diameter Range: processes 5–14 mm rebar in one system3. Precision Rib Forming: 3-side ribs ensure excellent bonding and weldability4. Continuous Production: no downtime for bundling, supports 24/7 operation5. Stable Quality: consistent performance for high-volume, standardized outputThe complete production line consists of the following units: pay-off stand, hydraulic descaling machine (2 sets), lubricant powder box (2 sets), cold rolling mill (2 sets), stress relief machine, high-speed straightening and cutting machine, automatic alignment rack, discharge rack, frequency servo control system, recoiler unit(optional).1. DecoilersProvides stable feeding of raw material.2. Hydraulic Descaling Machine (2 sets)Efficiently removes oxide scale and impurities from raw material surfaces.3. Lubricant Powder Box (2 sets)Ensures even application of drawing powder, reducing friction during rolling.4. Cold Rolling Mill (2 sets)Enables double-pass rolling for improved forming accuracy and dimensional consistency.5. Stress Relief MachineEliminates internal stress in the rebar after rolling, enhancing ductility and weldability. 6. High-Speed Straightening and Cutting MachineAchieves straightness deviation ≤3 mm/m and cutting tolerance ±2 mm.7. Automatic Alignment RackNeatly aligns and stacks the finished rebar for smooth discharge.8. Discharge RackSupports organized output of the final product.9. Frequency Servo Control SystemEnsures precise speed control and smooth operation throughout the line.10.Recoiler unit (optional): Rewinds straightened/cut bars into compact coils for flexible storage or transport.SpecificationModel No.LZDL150S-1LZDL180S-1LZDL180S-2Raw Material Diameter, mmΦ5.0-10Φ6.5-12Φ6.5-14Finished Rolling Diameter, mmΦ4 Φ5 Φ6 Φ7 Φ9Φ5 Φ6 Φ7 Φ8 Φ9 Φ11Φ6-12Max.Diameter Reduction Ratio1.52.52.5Max.Rolling Speed, m/min.150150/180150/180Overall Production Capacity, tons/month160026003000Actual Power Consumption, kw.h/ton18-2519-2219-22Wear Parts Consumption, RMB/ton4-62-32-3Standard Cut Length Range, m1.5 -121.5 -121.5 -12Cutting Length Tolerance, mm±2mm±2mm±2mmStraightness Deviation, mm/m≤3mm≤3mm≤3mmTotal Installed Power, kw75.5kw105.5kw155kwSpeed Control MethodVariable Frequency Speed ControlVariable Frequency Speed ControlVariable Frequency Speed ControlNumber of Sizing Traction Units222Straightening MethodPressure Roller Type or Rotary TypePressure Roller Type or Rotary TypePressure Roller Type or Rotary TypeNumber of Straightening Traction Units2/32/32/3Shearing and Control MethodServo Flying Shear or Servo Drop ShearServo Flying Shear or Servo Drop ShearServo Flying Shear or Servo Drop ShearLength Control MethodPhotoelectric Switch or Optional PLCPhotoelectric Switch or Optional PLCPhotoelectric Switch or Optional PLCDischarge MethodAuto.Align Rack with "Continuous Production"Auto.Align Rack with "Continuous Production"Auto.Align Rack with "Continuous Production"Roller Lubrication and Cooling MethodSaponification liquid or Drawing PowderSaponification liquid or Drawing PowderSaponification liquid or Drawing PowderTotal Equipment Weight, tonsAbout 7 tonsAbout 8.5 tonsAbout 9.5tonsSingle Rolling VS Dual Rolling & Straightening Line Comparison TableItemSingle Rolling & Straightening LineDual Rolling & Straightening LineCold Rolling Mills1 unit2 unitsRolling MethodSingle-pass rollingDouble-pass continuous rollingDecoilers2 units (for continuous feeding)1 unitHydraulic Descaling Machines1 unit2 unitsLubricant Powder Boxes1 unit2 unitsStress Relief MachineOptionalStandardStraightening Accuracy≤3 mm/m≤3mm/mCutting Length Tolerance±2 mm±2 mmStraightening MethodOnline straighteningOnline straighteningCutting MethodServo flying shear / drop shearServo flying shear / drop shearSpeed Control SystemVariable frequency controlVariable frequency controlLubrication MethodSaponification liquid or drawing powderSaponification liquid or drawing powderDischarge MethodAutomatic alignment dischargeAutomatic alignment dischargeContinuous ProductionYes (dual decoiler)No (single decoiler, requires downtime for coil change)Production CapacityMediumHighPower ConsumptionEnergy-efficientEnergy-efficientFootprintCompactSlightly largerApplicable CustomersSmall to medium-sized workshopsMedium to large factories, continuous production usersInvestment CostLowerHigherAutomation LevelModerateHigh, supports full automationCompliance with GB13788-2024YesYesCompany ProfileChongqing Landsail Technology Co., Ltd.A leading manufacturer specializing in rebar machinery, offering full-service solutions in design, production, sales, and after-sales support.1.
