HR or CR Steel Coil Cutting Machine Slitting Line

纵剪生产线Slitting Line

Features:

l  Low operating costs

l  High automation level to reduce non-productive times

l  Flexibility from customer-specific arrangement and design

l  Fully automatic strip threading systems

l  Fully automatic coil peeler for over-payoff and under-payoff uncoilers

l  Double slitters(optional), one slitter in production, the other in tool setting, interchanged

  after the production is finished, minimize the time for tool changing

l  Fully automatic adjustment of edge scrap guiding, automatic scraps discharge

l  Automatic clamping and unclamping of the cutting tools on the knife arbor

l  Automatic strip strand transfer systems

l  Special braking units for strips with high surface finish(optional)

l ESCL series slitter and CTL combined lines combine a slitter and a shear into one line. They not only can do slitting and recoiling but also cut-to-length and stacking of coil material.

Working process

 

Coil-loading——single head uncoiling——Coil-end-feeding & shoveling——2 pinch  rolls & 5-rollers 

leveling——head cutting----Hole Accumulator(1)-----aligning----Disc slitting——Scrap rewinder

——Hole Accumulator(2)——Pre-separator/Tensioner——Separator & Recoiler——Coils-discharging

——Hydraulic control——Electric control

 

Cage Loop

 The reverse loop accumulator is installed between the shear& welder and the forming line, Its purpose is to give enough time for feeding the new coil from uncoiler to shear & welder to cut and join end of the new coil with tail end of previous coil.
