BlueScope Steel is working on Australia’s largest steelmaking project, relining a dormant blast furnace.
The Australian steel industry is undergoing a historic transformation, and at the heart of it lies BlueScope Steel’s monumental $1.15 billion reline project for the No. 6 blast furnace at Port Kembla. This ambitious undertaking, touted as the largest steelmaking project in the country, marks a defining moment in the industry, blending tradition with innovation to ensure the sustainability of steel production in Australia for decades to come.
A Revival Decades in the Making
Port Kembla, located in the Illawarra region of New South Wales, has been an industrial cornerstone since 1928 when the first blast furnace began operation. This legacy of steelmaking has been integral to the region’s economy and development. However, as the current No. 5 blast furnace reaches the end of its life cycle, BlueScope Steel has embarked on a project to restore its dormant No. 6 blast furnace, a move critical to sustaining the plant’s annual output of 3 million tonnes of steel.
The reline, which began in 2023 and is expected to conclude by mid-2026, is a three-year endeavor with over 250 workers on-site daily. This project not only signifies the company’s largest financial commitment but also its unwavering dedication to Australian steelmaking.
A Modern Approach to an Age-Old Process
Blast furnace technology has remained relatively consistent over the past century. The process involves combining iron ore and metallurgical coal at high temperatures to produce molten iron, the raw material for steel. However, over time, the internal components of a furnace degrade due to extreme operating conditions, necessitating periodic relines to replace the brick lining and water-cooling systems.
What sets this project apart is BlueScope’s integration of modern engineering and cutting-edge technologies. For the first time, a top gas recovery system will be installed, converting exhaust gases into reusable energy. Additionally, a waste gas heat recovery system will be implemented, which captures and repurposes heat generated during steelmaking. This technology alone will produce enough energy to power approximately 20,000 homes, reducing reliance on external fuel sources.
Key Features of the Reline Project
- Technological Advancements
The reline project incorporates cutting-edge technologies designed to improve the furnace’s efficiency and reduce its environmental footprint. Innovations such as advanced refractory materials and modern automation systems will enable BlueScope to achieve higher productivity while minimizing emissions. - Job Creation and Economic Impact
The project has already created significant employment opportunities, with approximately 1,000 workers engaged in the construction and upgrade process. This investment not only supports the local economy but also reinforces BlueScope’s commitment to the Illawarra region, where the Port Kembla facility is a cornerstone of industrial activity. - Sustainability Focus
In line with global efforts to transition towards more sustainable steel production, the reline project emphasizes energy efficiency and emissions reduction. While traditional blast furnace operations are energy-intensive, BlueScope’s upgraded facility aims to set a new benchmark for environmentally responsible steelmaking.
Progress and Milestones
As of January 2025, the reline project has reached the halfway mark, with significant progress made on key construction and refurbishment tasks. BlueScope has maintained a strong focus on safety, ensuring that the project adheres to strict health and environmental standards.
The company has also invested heavily in training and upskilling its workforce to manage the complexities of the upgrade. This approach not only ensures the successful completion of the reline but also equips employees with the expertise needed to operate the modernized furnace.
Leveraging Global Expertise and Advanced Equipment
Given the scale and complexity of the reline, BlueScope has adopted an international approach by collaborating with global steelmaking experts, particularly from Europe, where some components for the furnace have been designed.
The project has also introduced new efficiencies in construction, such as the use of the southern hemisphere’s largest crane. This crane, with a boom extending 95 meters and a driver’s cabin 86 meters above ground, has revolutionized the way heavy materials are moved within the plant, significantly improving safety and efficiency.
Economic and Environmental Impacts
While the reline is a significant step forward for BlueScope Steel, it comes with its share of controversy. The federal government’s $136 million funding contribution has drawn criticism due to the plant’s carbon-intensive operations. BlueScope is one of Australia’s largest carbon emitters, and concerns have been raised about the implications of recommissioning a coal-based blast furnace for another two decades.
Despite these criticisms, BlueScope has emphasized that the reline is a bridge to green steelmaking. The upgraded furnace is designed to be retrofitted in the future to accommodate low-emission fuel sources, such as hydrogen. Furthermore, the company’s pilot green iron plant in Western Australia demonstrates its commitment to transitioning towards sustainable steel production.
Bridging the Gap to Green Steel
The debate over green steelmaking has gained traction as global industries strive to reduce carbon footprints. Traditional steel production relies heavily on coal, making it a significant contributor to greenhouse gas emissions. BlueScope acknowledges this challenge and has positioned the No. 6 blast furnace reline as a transitional solution.
According to Mark Vassella, BlueScope Steel’s CEO, the reline ensures the continuity of operations at Port Kembla while the company explores alternative steelmaking methods. These include smelting technologies and hydrogen-based solutions, both of which promise significant reductions in emissions.
“The two projects absolutely will work in parallel,” stated Justin Reed, the Blast Furnace Reline Project Director. “This project needs to be completed to ensure the Port Kembla steelworks continues to operate through the time that our company and other companies investigate the future iron-making sources.”
