Development of Smelting Reduction Ironmaking Process
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The production practice of COREX 3000 shows that COREX is a new type of ironmaking production method that has become mature in recent years. While achieving good environmental and social benefits, it also faces many problems. Production found that COREX 3000 has a high fuel cost and high production costs.
