Bringing HIsmelt back
HIsmelt is short for high intensity smelting. It is a direct smelting process for making liquid iron straight from the iron ore. The process has been developed to treat iron ore fines with minimum pretreatment, making the process more flexible in terms of the quality of iron ore it can treat. The process allows the use of non coking coal and iron ore fines with significant impurities. The core of the HIsmelt process is the smelt reduction vessel SRV which has a refractory lined hearth and water cooled upper shell. The process is carried out in this vessel. The refractory hearth contains the molten iron bath and liquid slag.
Analysis on Energy Efficiency and Optimization of HIsmelt Process
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron or hot metal. 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. HIsarna is considered one of the most promising developments in reducing CO 2 emissions from the steel industry. The very first attempts at applying cyclone oven technology in the reduction of iron ore took place at Koninklijke Hoogovens in the s. Cyclone technology had already been used successfully in different industrial, chemical processes and designers at Hoogovens thought it might be a strategy for improvement for their process. However, at the time they couldn't get it to work properly and the experiment was quickly abandoned.
