Hilden/Germany (Kocks) – The decision for Kocks was mainly driven by the performance and reputation of this ground-breaking Kocks technology with its now 22 references in the Chinese market place. Yonggang mainly produces SBQ products, such as alloyed steel, bearing steel, spring steel, gear steel, cold heading steel and tool steel, as well as special steel rods and wires. These high-quality products serve the automotive, aviation, marine, petroleum, nuclear power and wind power industries.With the implementation of the RSB in their ultra-modern 700,000t/a medium bar mill, Yonggang aims to roll round bar within the range of 16mm to 100mm diameter in straight lengths with tight tolerances and high production and process reliability, in order to serve the demanding market with highest quality consistency at lowest possible conversion costs. The heavy-duty „RSB 370++“ with four stand positions is seen as the quality and availability determining Reducing and Sizing unit, located behind 20 conti stands in horizontal/vertical arrangement.
