Case: ANDRITZ Oy
20 years of design and manufacturing cooperation with ANDRITZ Oy
ANDRITZ Oy is a leading global supplier of systems, equipment and services for the pulp and paper industry including wood processing, fiber processing, chemical recovery, and stock preparation. The company is owned by ANDRITZ AG of Austria.The cooperation between High Metal Oy and ANDRITZ Oy began in 2001 when High Metal was asked to design a new structure for the lime filter hood. The old structure was fiberglass and wanted a replacement stainless steel structure that was durable, easy to install and cost effective. The idea of using laser-welded cell structures as a hood structure arose. This resulted in a very light and strong structure. Successful deliveries have been made to dozens of pulp mill projects around the world. Also included are the largest factories of its kind in the world.
Picture above shows a lime filter hood in which laser welding has been used to fabricate the curved cell structures of the hood frame.
