Thanks to process data optimization, the pickling line and tandem cold mill in Tangshan Fengnan Steel which was EPC-supplied by CISDI successfully produced high-strength cold rolled strip (SAE1022) in early November, 2010 and has produced over 3mt high strength cold-rolled strips continuously and steadily since then, which are good enough in terms of thickness accuracy, profile and surface quality for its intended purpose (banding strap).

The pickling line and tandem cold mill has been producing extra-thin gauge (average thickness <0.4mm) products at high speed (over 1,000m/min.) steadily since its startup, featuring high gauge control accuracy (±2mm) and good profile.
