Big round bars up to 160 mm finished size are at the core of many safety‑critical and high‑load applications – from automotive and commercial vehicles to marine, energy and heavy machinery. With KOCKS 3‑roll RSB® technology, producers gain the precision, stability and flexibility needed to deliver these demanding products reliably and efficiently.
In all these areas, tight dimensional tolerances, high surface quality and consistent mechanical properties of large diameters are key to performance, lifetime and safety. This is where the right sizing technology makes a decisive difference.
KOCKS RSB® technology has long been a benchmark in special bar quality for small and medium dimensions. For big bars up to 160 mm finished size round, the proven 3‑roll technology offers specific advantages compared to conventional sizing methods.
In addition it offers flexibility across steel grades and dimensions, one‑pass family rolling, precise process control and best mechanical properties – leveraging efficiency and quality in a single 3‑roll solution.
The following schematic layout illustrates how an RSB® 500 can be integrated as a key sizing unit within a modern SBQ / big bar mill. It is not a fixed blueprint, but an example of how KOCKS 3‑roll technology fits into a big bar mill.
