Abstract
Fluidised bed technology for the direct reduction of iron ores allows the exclusive use of hydrogen as a reductant, offering a sustainable pathway for green steelmaking. A key challenge in this process is the sticking phenomenon, which causes defluidisation and disrupts operations. This talk will present a thermochemical investigation into how operating conditions—such as temperature, hydrogen supply, and ore composition—affect the formation of a low-melting liquid phase linked to sticking. The findings provide insights into minimising sticking risks and optimising the fluidised bed reduction process.
