Electrifying the steel industry

Electrification is a promising way of reducing the CO2 emissions in the steel industry, says Anders Björklund, President of Division Kanthal.

Steel remains one of the world’s most useful and in-demand commodities, yet its production processes are energy-intensive and produce vast amounts of carbon dioxide (CO2). On a global scale, the steel and iron industries account for some 7 percent of CO2 emissions. Particularly emission-intensive are heating processes, which traditionally are fueled by gas or oil. But Kanthal provides electric heating as a viable alternative.

SMT shifted to an electric induction furnace, already in 1921, and in addition to using recycled steel in the production substantially bringing down emissions.

But with our technology, covering furnace temperatures up to 1500°C, you can electrify any heating process in steelmaking

“There are many misconceptions about electric heating. For instance, that it’s not able to reach certain temperatures. But with our technology, covering furnace temperatures up to 1500°C, you can electrify any heating process in steelmaking,” says Anders Björklund, President of Kanthal. “As we have proved, Kanthal has the technology, the thermal expertise, the resources and the global footprint to electrify all the highly energy-intensive heating processes.”

In addition to eliminating CO2 and NOx emissions and improving thermal efficiency, electric heating also provides precise temperature control. The reduction of noise and exhaust gases means a cleaner, quieter production process and work environment.

“While current heating technology is predominantly gas-fired, electric heating processes offer unique opportunities to reduce use of fossil fuels while increasing thermal efficiencies and potentially improving work environments”, says Dilip Chandrasekaran, Business Development Manager Steel.
