HR division has developed a wide range of hot rolled coils. After
rolling, a few sections remain damaged. Improper
winding tension often leads to telescopic winding. TISCO wanted a coil
processing line which could be used to unwind these coils, so
that the defective sections are traced and then sheared off, followed
by recoiling. As the name suggests, the function of the line is to
divide bigger coils to smaller ones.
proposed an automatic Coil Dividing Line which could be
operated at a top speed of 50 MPM. The
line encompasses a dual stub uncoiler (508 to 620 mm range), pit
mounted coil car, hold down roll, snubber roll, peeler, pinch roll,
straightener, hydraulic crop cut shear, inspection conveyor, reject
stacker trolley, side guide, multi-roll tensioner, deflector roll,
recoiler with overhung (cantii-lever) three segment mandrel with
gripper, hold down roll, coil car, coil weighing station.
Transportation of coils from coil storage to mandrel and vice versa
is by means of entry and exit Coil Cars. Precise winding tension
control is possible by drag generator mechanism.
