Jeffersonville, IN – Eagle Steel Products,
Inc, a flat rolled steel distributor and coil processor located
near Louisville, KY, has installed a new precision double-loop
Turret Head coil slitting & surface inspection line with in-line
shape correction capability in its expanded 170,000 square foot
barge and rail serviced facility on the Ohio River in
Jeffersonville, IN. Eagle Steel provides high-quality precision
coil slitting, surface inspection, and leveling services for
carbon and stainless steel producers, automotive and appliance
manufacturers, as well as other OEMs.
The new Braner/Loopco slitting/inspection
line is capable of processing 80,000# x 76" wide surface
critical coated steel as well as 300 and 400 series stainless
steel coil in gauges from .009" through .187" at speeds to 1,200
FPM.

Double-Loop Processing – The line has
the ability to process coils in tight line, single loop, and
double-loop operating modes. Based upon material, gauge, and
duty (surface inspection, edge trim, multi-cut slitting), Eagle
Steel can select the operating mode that would produce the best
quality and best operating efficiency. For example, the tight
line mode is commonly utilized for edge trimming and surface
inspection. Mid-gauge cold rolled is normally processed in the
single loop mode, and double-loop is commonly selected for
processing light gauge surface critical coil. In the double-loop
mode the DC motor driven Uncoiler drives the strip into a free
loop ahead of the slitter, causing the strip to be steered and
slit under zero back tension conditions. Zero back tension
produces tighter slit width tolerances because the strip lays
flat into the slitter knives. Zero back tension produces a
better quality slit edge because slitter knife slippage is
virtually eliminated. Edge trim width can be reduced with zero
back tension since the strip can be side guided into the slitter
without the fear of rolled-up edges. Higher slitting speeds can
be achieved and entry tension induced camber can be eliminated
because thin gauge coil "wobble" (coil OD eccentricity) is
isolated from the slitter by the free-loop.

Turret Head Slitter™ – The Eagle Steel line is equipped
with a quick-change Turret Head Slitter with three (3) 9.500"
heads. The Turret Head Slitter is easier and faster to re-tool
than any other slitter design, and has the added benefit of
changing heads in one-minute. A 300 HP DC motor driving the
Turret Head Slitter allows single loop slitting of up to 24 cuts
in .075" at 1,200 FPM.

Surface Inspection – Processing
surface critical material often requires that coils be quality
inspected for surface defects. The Eagle Steel line is equipped
with a surface inspection station equipped with multiple
fluorescent lamp banks as well as high-intensity strobe lamps to
highlight surface scratches, dents, or other surface defects.
Surface defects are visually identified, located, and recorded
by an inspector as the coil is processed.
In-Line Shape Correction – The Eagle
Steel line is equipped with a Cluster Leveler™ capable of
eliminating strip shape defects such as center buckle, wavy
edges, and cross-bow from the strip. The Cluster Leveler is a
corrective roller leveler with adjustable back-ups supporting
work rolls that range in size from 3.000" to 1.500". The
patented work roll design gives the Cluster Leveler the unique
ability to eliminate strip shape defects through the entire
.009" to .187" gauge range by applying large or small diameter
work rolls to the strip depending on gauge and yield strength. A
PLC eliminates leveler set-up trial and error time by making the
set-up fully automatic.
