Fabrication of Wet Scrubber and Structural Frame for NZ Steel New Zealand Steel, the country’s leading producer of flat rolled steel products, operates from the Glenbrook Steel Mill, 40 kilometres south of Auckland. Serving industries such as construction, manufacturing, and agriculture, the company is dedicated to enhancing sustainability and efficiency in steel production. As part of the Melters Extraction upgrade, Taurus played a pivotal role in fabricating key components for the project. This upgrade was designed by Vortex to improve the performance of the Melter feed bin de-dust system, which removes hot dust and fumes generated during the batch feeding of hot materials into the 24 charging bins (12 per Melter) associated with the two Melter units. Taurus’ Contribution Taurus’ scope of work in this project included the fabrication of the six-metre-high wet scrubber and the structural frame. Key contributions included: Fabrication of the Wet Scrubber: Taurus constructed the wet scrubber using high-grade 3Cr12 stainless steel, selected for its ability to withstand the challenging environment of high temperatures and abrasive materials. The scrubber was designed to effectively remove remaining dust load and gaseous emissions before they are safely released into the atmosphere. Structural Frame: The structural frame was fabricated with carbon steel to provide robust support for the system. Taurus ensured precise engineering and manufacturing to handle the load requirements and ensure durability in the demanding operational environment. Taurus’ expertise in fabrication ensured the successful completion and delivery of the wet scrubber and structural frame. A complete trial build of the system was performed to confirm that all components were ready for seamless installation. The system was installed on schedule and is operating as intended. With the upgraded system in place, New Zealand Steel has noted an improvement in the work environment, contributing to their goals for sustainability and efficiency under Project Electron.
