The following general conclusions can be drawn from these publications: a higher DRI fraction resulted in a rising energy consumption, especially when the acidic gangue content increased; due to the enhanced slag volume, the iron yield decreased as more Fe was lost in the slag; regarding tramp elements such as P or Cu, an increased DRI ratio ...
Energy efficiency is vital for the sustainable future of the iron and steel industry. As mentioned in the Introduction, energy cost takes 20 40% of steel manufacturing costs [4], and, naturally, there is a strong incentive to save energy consumption in the process. Many countries have tried to improve the energy and resource efficiency of ...
1. Introduction. Iron and steel manufacturing is one of the most energyintensive industries worldwide. In addition, use of coal as the primary fuel for iron and steel production means that iron and steel production has among the highest carbon dioxide (CO 2) emissions of any to the International Energy Agency (IEA), the iron and steel industry accounts for the largest share ...

Soaring renewable energy consumption of % will not be enough to displace CO2 emissions from coal and oil, which will represent around 72% of global emissions in 2040.
The energy saving occurs in case of charging HDRI because of less requirement of energy in the EAF for heating the DRI to its melting temperature. The rule of the thumb is that the electricity consumption is reduced by around 20 kWh/tLS (kilowatt hours per ton of liquid steel) for each 100 deg C increase in the charging temperature of DRI.
Energiron DRI is a highly metallized product with controllable carbon content in the range of to % which generates chemical energy in the EAF melting process.

Any coal with an ash melting temperature above 1050°C and a 10%40% VM content can be used in the Circofer. Coal with ash content <15% is preferable to keep the circulating load in the reactor, and in the case of direct charging into a smelter, the slag volume to a minimum (von Bitter et al., 1999). DRI produced by the Circofer process (>93% ...
