ArcelorMittal to restart two U.S. furnaces. Steel maker ArcelorMittal said on the 20th it will restart two idled blast furnaces in the U.S., while a union official said a U.S. Steel Corp. furnace is also being prepared to reopen. The news of steel production returning in America's industrial heartland came as statistics showed world steel production in July rose to its highest this year. Europe-based ArcelorMittal, the world's largest steel maker, said it will resume production at its No. 6 blast furnace at Indiana Harbor, Ind., in early October.
