The Kocks PWW 530/4 for voestalpine Tubulars with 4-roll stands

Rolling mill for the production of seamless hollow sections supplied to tube company VOESTALPINE Tubulars, based in Austria, has successfully commissioned a profile rolling mill engineered by Friedrich Kocks GmbH & Co KG.

Following the completion of all work and successful commissioning, the new equipment is now fully integrated into the hot tube rolling mill at the Kindberg site in Styria. The award of the contract was preceded by an intensive technological discussion on the design and construction of a solution for rolling seamless hollow sections. The centrepiece of the profile rolling mill, called PWW 530/4, consists of four consecutive 530mm stands, each equipped with two horizontal and vertical rolls facing each other. These four rolls in the stands are individually driven. Based on Kocks’ proven 3-roll stand design, they feature calibre adjustment and allow for fast roll changes, providing high flexibility in production planning. The scope of supply also included the corresponding equipment for the roll shop. voestalpine Tubulars, with its extensive experience in the production of seamless round tubes, is now also capable of producing seamless, hot rolled square and rectangular hollow sections up to large formats and wall thicknesses. The Kocks Group, headquartered in Germany, is a global supplier of rolling mill equipment for sizing applications and was founded in 1946.
