The KOCKS Profiler is a modern rolling solution for producing seamless, hot‑rolled square and rectangular hollow sections. Building on decades of KOCKS expertise in tube and section rolling, it introduces an innovative four‑roll stand design that combines precision forming, high flexibility and efficient operation for demanding structural applications.
The KOCKS 4‑Roll Profiler is designed to roll seamless square and rectangular hollow sections that meet stringent market and standard requirements, including DIN EN 10210‑2. The profiles are suitable for demanding applications in construction, mechanical engineering and energy infrastructure – wherever electric resistance welded (ERW) tubes are not approved or not desired. This opens up new opportunities in value‑added, seamless structural hollow sections.
Operating at rolling speeds between 0.8 and 5.0 m/s and process temperatures from 820 to 950 ℃, the profiler is engineered to deliver reliable, high‑quality production across a broad operating window. Wall thicknesses are variable and can reach up to 25 mm, enabling a wide range of structural designs.
At the heart of the profiler is a stand design with four driven rolls positioned at 90° angles. This configuration enables efficient and controlled forming of four‑sided profiles from round hollows. Individually driven rolls and precise roll gap adjustment ensure consistent forming conditions and stable product geometry. The adjustable stands provide exceptional flexibility in the forming process, allowing producers to adapt quickly to different formats and wall thicknesses.
