Swelling Behavior of Iron Ore Pellets during Reduction in H<sub>2</sub> and N<sub>2</sub>/H<sub>2</sub> Atmospheres at Different Temperatures
Abstract
<jats:p>The need to develop green steelmaking techniques has led to the replacement of reducing agents such as CO with H<jats:sub>2</jats:sub>. H<jats:sub>2</jats:sub> and N<jats:sub>2</jats:sub>/H<jats:sub>2</jats:sub> mixtures can be used for the carbothermal reduction of iron ore. Herein, the reduction swelling index (RSI) of iron ore pellets in a forming gas (N<jats:sub>2</jats:sub>/H<jats:sub>2</jats:sub>) atmosphere at temperatures of 700–1000 °C is investigated and it is compared with that in pure H<jats:sub>2</jats:sub>. It is showed in the experimental results that the RSI increases with increasing temperature for both the H<jats:sub>2</jats:sub> and N<jats:sub>2</jats:sub>/H<jats:sub>2</jats:sub> atmospheres. The maximum swelling is reached approximately 5 min into the H<jats:sub>2</jats:sub> reduction process, while in the N<jats:sub>2</jats:sub>/H<jats:sub>2</jats:sub> atmosphere, it is reached after 25–45 min of reduction, depending on the temperature. When the reduction temperature exceeds 900 °C, the RSI is greater than 20%. Scanning electron microscopy/energy‐dispersive X‐ray spectroscopy is performed to detect the changes in the microstructure and chemical composition of the samples. The nonreduced areas in the reduced pellets during the N<jats:sub>2</jats:sub>/H<jats:sub>2</jats:sub> reduction process are analyzed using light optical microscopy.</jats:p>
