Electric steelmaking

Arccess® EAF technology - solutions for your success

Nothing succeeds like success with ARCCESS® electric arc furnace technology from SMS group. All components are dedicated to cutting the cost of electric steel production. This makes your investment pay off even faster. We build on decades of experience in electric-arc furnaces, metallurgy, and optimized processes to offer you the most cost- effective solutions. What sets ARCCESS® furnaces apart is their highly efficient electricity utilization. That's because they come with future-oriented burner and oxygen-injector technology. That gives you high productivity at low production costs.

Arccess® EAF - electric-arc furnaces

Success based on experience

We have banked a valuable store of experience from more than 100 years of development, construction, and commissioning of electric-arc furnaces.

That's why, with almost 1,400 electric-arc furnaces in both new construction as well as revamp projects, SMS group ranks among the world's leading suppliers in the industry.

Here is what makes our electric-arc furnaces stand out:

  • Modular design
  • Standardized component groups
  • Low maintenance

Your benefits:

  • Lower production costs
  • Higher productivity
  • Better-quality steel grades
  • Steeper run-up curves
  • Longer running times with less maintenance

Conarc® (Converter arcing) - two in one

Double versatility

You get twice the performance with CONARC®. That's because these furnaces combine the technological advantages of electric-arc furnaces with the power of the conventional converter blowing process. They consist of a single production unit with two identical shells. Depending on the steel grade as well as the availability and price of charge materials, you can vary the percentages of scrap, hot metal, and sponge iron. Just as flexible with CONARC® is your choice of energy sources. CONARC® comes optionally with one swiveling or two stationary top lances for oxygen blowing. Plus, there are devices for bottom stirring that we integrate in the shell floor. The process consists of two stages. First: the converter phase involves blowing oxygen onto the melt through the top lance to decarburize it. Second: the electric-arc furnace phase uses electric power to melt the solid material and overheat the bath to tapping temperature.

SHARC - shaft arc furnace

The cost-effective melting machine

Here, we joined forces with Greek company Hellenic Halyvourgia SA (HLV) to develop an innovative, unique scrap preheating method: the SHARC furnace process. That slashes energy consumption and simultaneously boosts economic efficiency. Also included are state-of-the-art automation systems and green technologies that meet strict occupational health and safety as well as environmental requirements. Meanwhile, the first SHARC (shaft arc furnace) has been operating successfully in Greece for 14 years. Central to the cooperation between HLV and SMS is further technological improvement of the furnace as well as training and instruction courses, plus support with commissioning new furnaces.

Arccess® - primary energy melter

Primary energy directly converted into heat

Our innovative PEM is designed to operate with natural oxygen/gas burners. As part of a joint project with ArcelorMittal, we built an industrial-scale PEM plant at the company's steelworks in Ghent, Belgium.

S/EAF steady electric-arc furnace

Ready, steady – low-cost heat

Using our ARCCESS® steady EAF (S/EAF®), you achieve continuous operation for up to a whole week. It's an all-new furnace type that combines innovations with proven technology. What made this possible was our longstanding experience with submerged-arc furnaces, electric-arc furnaces, and CONARC® technology. The result? A completely novel electric-arc furnace. This ensures you'll benefit from 30 percent higher productivity as well as lower energy consumption due to the reliable continuous process.
