CRGO CRNGO Silicon Steel Slitting Machine For Transformer Electrical Steel

CRGO CRNGO Silicon Steel Slitting Machine For Transformer Electrical Steel Silicon steel is low carbon special steel ≤C(0.08%), Si(1.0～4.5%), its producing process is complicated and making cost is higher. It has characters of high magnetoconductivity, low coercive force and high resistivity and thus little loss of hysteresis and eddy current, the purity of silicon steel sheet must be high, sheet surface must be very flat and clean, silicon steel sheet covers 1% of whole steel production, whose main application is motors, transformers, electric appliances, meters, etc. In this condition, the processing equipment for silicon steel sheet must be very precise. Max yield strength: 450Mpa, max tensile strength: 600Mpa Hardness HV100-220, elongation 15% -45% Composition and Parameters: 1)Coil preparing saddle, 10T load 2)Single Mandrel uncoiler (508mm mandrel, with 7.5KW press roller) 3)Coil-head straightening and shoveling device 4)double pinch rolls and coil head shear (7.5KW AC) 5)Pit accumulator 1 (3m long, 3m deep, 1.6m wide) 6)Side guide before slitter (300-1300mm adjustable range) 7)Slitter(double heads fast exchange is optional), 160mm arbor, 75KW DC 8)edge scrap reeler(located below transmission table)  4KW variable frequency 9) pit accumulator 2  (3m long, 4m deep, 1.6m wide) 10)pre-separator & Tensioner, Rear shear, Deflector Roller 11)Recoiler with Separator press bracket  508mm seamless mandrel 12)Coil Discharging Car, 10T load 13)Hydraulic system, Pneumatic system  7.5KW pump  14)Electric control system Parameters: Silicon steel Slitting Line 150mpm Parameters Coming steel coils ID508mm, 610mm, OD1500mm, coil weight 10T Finished baby coils ID508mm, OD1500mm, coil weight 10T max Mother coil width 300-1250mm Baby coil widths 20mm -1250mm Number of slitting 12slits Main motors Slitter 75KW + Recoiler 90KW Slitter knife ID180 x OD300 x 10mm SKD11 HRC58-61 Recoiler mandrel 508mm seamless mandrel Slitting speed 0-150mpm adjustable Configuration Siemens PLC, Parker Drive, Vitory Valves Slitting precision Slit width ±0.10mm; Camber ±0.1mm/m; bur 5% of thickness; recoil hump<0.5mm Configuration: Part Material, Processing, Brand shaft, axis, rollers 40Cr,HB250-275, surface HRC55-58 Slitter arbor 42CrMo forging, HB280-300, surface MF HRC50-55, hard chrome coating, surface polishing Frame, bases Q235-A ,Q345steel plates welding, annealing treatment Gearbox body Q345 plates welding, heat treatment, sand blasting, primer painting Gears: 40Cr forging steel, HB240-255, teeth face hardened, teeth ground Uncoiler Recoiler Segments: 45# Cast steel, tempering, hard chrome coating and polishing Hydraulic pump Yuken pistion variable pump PLC Siemens S200 Bearing HRB, ZWZ, SKF Pneumatic parts Airtac,SMC
