The machine is the roller type cold straightening level machine, which is specially used to straighten the angle steel when its straightness can not reach the requirement. The angle steel can be straightened one time at passing the machine. If the accuracy of angle steel can not reach the requirement after one time straightening, the angle steel can be straightened at most two times. Straightness accuracy: 1/1000L. Material of angle steel: 16MnMain specifications Model Parameter Name W50-10 W50-16 W50-20 Range of straightened angle steel (mm) ∠100×100×10 -∠40×40×4 ∠160×160×16 -∠70×70×7 ∠200×200×20-∠80×80×8 Total straightening force (KN) 1400 2800 5590 Roller quantity 9 9 9 Roller diameter (mm) 340 420 530 Structural type cantilever type gantry type gantry type Driving type driving respectively driving respectively driving respectively Total power (kW) 16 44 74 Straightening speed (m/min) 15 20 15 Straightening accuracy 1/1000L 1/1000L 1/1000L Press method manual manual Manual Overall dimension (L×W×H)mm 2240×1818×2060 3440×2158×1750 3800×2460×2800 Weight(kg) 7500 1500 32000
