Linz/AT (Siemens VAI) – A two-strand rod mill originally designed to produce low carbon and medium carbon steel for Wuhan Iron & Steel has successfully been upgraded by Siemens VAI. The mill designed to produce 700,000 tons of steel per year before achieves now a record production of 850,000 tons of steel per year and now produces quality carbon at higher speeds with greater mill utilisation. Wuhan Iron & Steel, China’s oldest steel maker, built a two-strand rod mill in 1996, but when market demand shifted to higher quality products and heavier coils, it began an upgrade process. “Together with the increase of production also the product mix has moved from 85 percent low carbon and medium carbon steel, producing 1.8 ton coils, to 70 percent quality carbon steel grades,” reported Michael Xuan of Morgan Construction, the U.S. based specialist of Siemens VAI for high speed wire rod mills. Wuhan today is the largest tire cord producer in China, with 250,000 tons per year dedicated to 5.5mm coil. The upgrade was completed in just 58 days.
