Medium Gauge Slitting Lines Working procedure:
Medium Gauge Slitting Lines, also called metal coil slitter, is a
kind of production line to break down master coils into smaller
coils of a particular width. The thin sheet slitting line is made
up of coil-loading car, single mandrel uncoiling, coil-end-feeding
and shoveling, double roller pinching feeding,
three-roller-leveling, end-cutting, strip-aligning, disk shearing,
scrap reeling, hole accumulator, pre-separator, tensioning,
recoiling ,coil down car, hydraulic control, and electric control.
In the beginning, the coil is loaded on the coil car by crane and
brought to the uncoiler by operating the coil car. Coil car
centralizes the coil with the uncoiler mandrel and the coil is
mounted on the uncoiler. Mandrel is expanded. Snubber roll rotates
the coil. Peeler breaks the straps and brings the pre end upto
Pinch roll. The Pinch roll drives the coil end upto the slitter.
Then its drive is disconnected. Slitter moves the slitted strips
further. Slitted strips are threaded through loop table and drag
tensioner into the recoiler drum. Recoiler winds one turn on loose
coil.
Then drag tensioner and loop are put into operation. Slitter and
recoiler run simultaneously in synchronization. As the coil build
up, the recoiler rpm correspondingly goes down to keep desired
constant line speed. This process goes on until the end of coil on
uncoiler. The slitted coil is pushed on the exit coil car through a
pusher plate operated by hydraulic cylinder. The side slitted scrap
is wound on the scrap winder units provided on both sides of the
slitter.
