Emerging Technologies for Iron and Steelmaking

The IFCON process, developed by ISCOR in South Africa, is capable of producing steel directly from coal and iron ore. 1 In this process, coal and ore are added continuously to a channel type induction furnace containing a slag-metal bath. Electrical energy is supplied by the induction furnace for heating and stirring the bath.

How the global steel industry is cutting out coal The

How the global steel industry is cutting out coal The

May 01, 2021 Companies like SSAB have developed plans to eliminate coal from their steel plants. In place of coke, derived from coal, the company plans to use clean hydrogen. Like carbon, hydrogen can also strip oxygen from iron ore to make the pure iron needed in steel-making. But in this reaction, the resulting “emission” is H20. Photo: SSAB
