Algoma Steel EAF Melt Shop Building
Sault Ste. Marie, ON

Algoma Steel EAF Melt Shop Building

Algoma Steel Inc. is constructing two state-of-the-art electric-arc-furnaces (EAF) to replace the existing blast furnace and basic oxygen steelmaking operations. The transformation is expected to reduce Algoma’s carbon emissions by approximately 70%, making the project among Canada’s largest of GHG reduction efforts.

Algoma Steel worked with Danieli and JNE Engineering on the new Electric Arc Furnace at Algoma’s flagship plant in Sault Ste. Marie, Ontario.

Walters will use Algoma’s steel plate products to fabricate the heavy structural components and work with the local industrial contractor, SIS Manufacturing Inc., to fabricate these key elements. Onsite assembly of the building structure commenced in the fall of 2022.

Facts & Figures
  • 15,000 Ton project
  • Completion date expected in December 2023.
  • The main building is almost 1,000 feet or 350m long.
Our Role

Walters is providing the detailing, supply and installation of structural steel, heavy crane girders, stick steel and plate modules. Additionally, Walters is responsible for all the connection engineering on the project.

Walters has now successfully completed the erection of the main Algoma Steel Electric Arch Furnace building, signifying a pivotal phase in the project’s evolution.

Now, we have shifted our focus to the installation of 27 impressive 40ft tall dust hood modules, erected atop the towering 180ft building. Leveraging modular construction methods, we aim to maximize safety, operational efficiency, and substantial cost savings.

This approach reflects our unwavering commitment to delivering projects on time and optimizing resources.

Overcoming Challenges

The EAF dust hood above the furnaces will exhaust all smoke and heat through an intricate duct system to the scrubbers to minimize environmental impacts. The dust hood design and installation has been a challenge, given the weights of approximately 900 tonnes and the need for a 450-ton crane for final placement.
