An Analysis of Long-Process Ironmaking in a Reduction Smelting Furnace with Hydrogen-Enriched Conditions

Metals, 2023
The blast furnace and basic oxygen furnace (BF-BOF) is still the main process used for the production of iron and steel in China. With the approach of the “dual carbon” target, the iron and steel industry needs to transform and upgrade to “green” and ...

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.
