The private Xinji Aosen Steel Group was established in 2002. The company is engaged in iron and steel smelting, steel processing, the production of building materials, and international trade. With a workforce exceeding 8,000 employees, Xinji Aosen currently boasts an annual production capacity of 5.05 million metric tons in various product categories, including billets, wire rod steel, construction steel, high-quality carbon construction steel, welding and high-speed steel wire, as well as galvanised wire.

The now made investment in a state-of-the-art 700,000 metric tons per annum Special Bar Quality (SBQ) rolling mill is a significant milestone for Xinji Aosen, marking its entry into SBQ straight bar production for the first time. Positioned after 21 H/V-stands, the Kocks Reducing+Sizing Block will finish bars onto the cooling bed within a dimension of diameter 20.00mm to 90.00mm with the highest dimensional tolerance.

The scope of supply further includes the remote control for stand and guide adjustments, the equipment for the roll shop, and the further advanced “Bamicon” Octopus software that assists operators in the stand and guide preparation and supports the entire tooling process. The commissioning of the “RSB” is scheduled for the end of 2024.
