All industries are under pressure to reduce emissions and contribute to decarbonization. But the iron and steel industry is under more heat than most other verticals. It’s in the crosshairs of environmental groups and politicians because it accounts for 2.6 gigatons of carbon dioxide emissions annually. That amounts to 7% of the global total—more than all worldwide road freight, more than all of Russia, and more than the entirety of the European Union.
About 30% of HBI produced is used across the automotive supply chain. Other major use cases are in plating for wind towers and steels for electricity transmission and solar arrays.
Steel service centers must adapt
One type of DRI gaining traction is hot-briquetted iron (HBI). It’s an environment-friendly alternative to scrap and imported pig iron. Natural gas-based HBI is being used in some U.S. blast furnaces as a way to shrink the carbon footprint of steel making. It increases productivity while reducing the amount of coal or coke needed in the process. HBI is basically a premium form of iron compacted at a temperature of 650°C or more. It has a density of 5,000 kilograms or more per cubic meter.
At one Cleveland-Cliffs facility, for example, iron ore is fed into the top of a 450-ft furnace and subjected to process gas that helps to strip out the oxygen. The material coming out of the bottom of the tower is reduced further and put through a briquetting machine to be sent to blast furnaces across the U.S. to be made into steel. Because the briquettes have a far lower surface area than what is produced by traditional processes, there’s far less oxidization.
The tightening of environmental regulations is just one of the factors that have made life difficult for the U.S. iron and steel industry in recent years. Nevertheless, the U.S. remains third in the world, behind India and China, in producing raw steel, with 88 million tons per annum (MTPA) of steel. It’s also the sixth-largest producer of pig iron, with 29 million metric tons of pig per annum. Major steelmakers in the U.S. include Cleveland-Cliffs, Carpenter Technology, Commercial Metals Co., Nucor, Steel Dynamics, and U.S. Steel.
According to Metal Center News, the top 50 service-center companies in North America employ 63,500 people and reported sales of $85 billion in 2023, a jump of more than $7 billion from the prior year. Clearly, this is a vibrant and expanding sector of the economy. However, steel service centers across the U.S. should apprise themselves of shifting market conditions and adapt to the winds of renewable and decarbonization change. Customers will be demanding DRI-based steel more and more. Many will be willing to pay more to obtain it.
With FABTECH 2024 in Orlando, Florida, fast approaching (Oct. 15–17), many in the steel industry are expected to attend. Some will be part of the manufacturing side of the iron and steel sector, some will be involved in fabrication, and others part of steel service centers.
However, Market Research Future predicts that the industry’s future is bright. By 2023, the market was valued at $1,787.45 billion and projected to grow from $1,826.59 billion in 2024 and sustain an annual growth rate of 3.47% until 2032.
Renewables and decarbonization affect steel demand
So, how is the industry doing as a whole as it faces a raft of changes?
• Stiff environmental regulations and responsibilities
• The arrival of artificial intelligence (AI)
• Changes in the U.S. manufacturing sector and supply chain
• Changing availability of materials
The industry has demonstrated time and again its willingness to adapt with the times and adopt the latest technologies. That is why shows like FABTECH 2024 are so vital to manufacturers and fabricators. The event showcases the latest techniques, technologies, and successes from across the industry.
