Global InformationHIsarna ironmaking process information
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron (pig iron). The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place. The process does not require the manufacturing of iron ore agglomerates such as pellets and sinter, nor the production of coke, which are necessary for the blast furnace process. Without these steps, the HIsarna process is more energy-efficient and has a lower carbon footprint than traditional ironmaking processes.[1][2][3][4] In 2018 Tata Steel announced it has demonstrated that more than 50% CO2 emission reduction is possible with HIsarna technology, without the need for carbon capture technology.[5][6]
The HIsarna process was developed in stages and with pauses at Koninklijke Hoogovens / Corus IJmuiden / Tata Steel IJmuiden, starting in 1986. The final stages were made possible through the Ultra-Low Carbon Dioxide Steelmaking (ULCOS)[7] consortium and cooperation between former Corus (now Tata Steel) and the Rio Tinto Group.[8] The latter contributed their HIsmelt (short for "high intensity smelting") technology[9] to the final design of the installation, prompting the name HIsarna for the process ("HI" from "high intensity" and "sarna" from Isarna, a Celtic word for iron).[4][10][11]
HIsarna is considered one of the most promising developments in reducing CO2 emissions from the steel industry.[12]
