Armorel, AR - Maverick Tube has installed a massive Braner/Loopco slitting line to produce high-strength heavy-gauge slit coil at its Armorel, AR structural tube facility. The new "Turret Head " slitting line is designed to process 90,000# x 84" wide 100,000 PSI yield strength hot rolled coil in gauges from 5/8" down to 14 gauge. More than 1,100 HP is employed to process the high-strength heavy-gauge coils at line speeds to 420 FPM.
90,000# x 84" x 5/8" Slitting Line
Coil Storage & Loading: 90,000# x 84" OD master coils are staged at the entry end of the line on coil saddles. A hydraulic coil buggy retrieves coils from the saddles and loads the coils onto a Cone Uncoiler. The cones handle 20"-34" ID coils. A massive Coil Hold-Down anchored to the floor snubs the coil outer wrap and assists threading the coil. The powered hold-down roll "floats" in its frame to allow the coil to be laterally positioned while the roll is engaged.
Entry Coil Saddles and Cone Uncoiler
Entry Section: The lead end of the coil is peeled and fed into Entry Pinch Rolls and a 5-Roll Straightener. The Straightener removes coil set curvature allowing for faster strip threading, and removes the coil "tail hook" during tail-out.
