Steel Coil Services Installs
High-Speed Oscillate Coil-Winding System

Tuesday, April 23, 2002
 
Steel Coil Services has installed a high-speed oscillate coil-winding system, from Braner USA, Inc., Schiller Park, IL, at its Port of Catoosa, OK, coil-processing plant. The system can produce jumbo oscillate-wound coils at line speeds to 1500 ft./min. Oscillate-wound coils are said to contain ten times or more lineal strip footage than narrow-ribbon-wound slit coils, reducing metalforming production losses related to fresh-coil threading. The new system can take 70,000-psi-yield-strength carbon and stainless-strip steel in gauges from 0.028 to 0.060 in. and from widths of 3/8 to 3/4 in. and rewind it into 6000-lb. 21-in.-wide oscillate coils. It can generate coils to 60-in. dia. without side plates or coil spools for coil containment. The system is equipped with a vertical payoff uncoiler capable of handling a 15,000-lb. stack of narrow-width slit coils. A flash butt welder and weld annealer connect the tail end of one slit coil to the lead end of a fresh coil. A microprocessor servo system controls the rewind oscillation rate, helix pitch, gap between strip widths and overall oscillated coil width.
