Direct reduced iron (DRI) is produced from the direct reduction of iron ore into metallic iron by a reducing gas or elemental carbon produced from natural gas or coal. By using ultra-high-tension steel rolling technology for automobiles and refining technology with a special steel electric furnace that can control fine components, Hyundai Steel has produced 1.0 gigapascal (GPa)-class steel sheets capable of withstanding 100 kilograms (220 pounds) of load per unit area.
There have been some cases that produced automobile steel using electric furnaces, but Hyundai Steel said that none of them were high-strength products with a 1.0 GPa or higher. "With the success of this trial production, we have confirmed the possibility of supplying low-carbon high-end products using electric furnaces,” an unnamed Hyundai Steel official said in a statement on September 13.
"We will preemptively respond to the low-carbon product market through carbon neutral technology," the official said. The company has unveiled its scheme to produce low-carbon and high-quality steel products through its electric furnace-based carbon-neutral steel production system called "Hy-Cube" and a hydrogen-based production system.
