The proposed slitting line
will function as longitude cutter to slit jumbo coils into baby
coils for final usage. In the beginning, jumbo coil is loaded on
the coil car by overhead crane and brought to the decoiler by
operating the coil car. Coil car centralizes the coil under
decoiler’s mandrel and the coil is mounted on the decoiler. 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 tension station
into the recoiler’s 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 decoiler. The slitted coil is pushed on the exit coil car
trolley 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.
