voestalpine Tubulars in Austria has successfully commissioned the 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 dialogue on the design and construction of a solution for rolling seamless hollow sections. The centerpiece of the profile rolling mill, called PWW 530/4, consists of four consecutive 530 mm 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 caliber 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.
