This study explores the main differences between Na and K on the Blast Furnace operation focusing on the effects of Na₂SiO₃. The experimental method involved simulating thermodynamic parameters comparing traditional alkalis oxides, carbonates and silicates. In addition, a technological apparatus was used to describe slag properties and gangue phases at high Na content. The results indicated...

By developing decarbonisation plans, the European steel industry shows its commitment to the European climate change targets. The main element in these plans is a transformation step involving a transition from carbon-based blast furnaces to green hydrogen-based direct...
In recent years, reducing CO2 emissions in the steel industry has been demanded from an environmental conservation perspective. As a partial substitute for coke, a reducing agent injected into the blast furnace, the injection of H2 is being considered. The reduction reaction of ore by H2 is an endothermic reaction, and there is concern about a decrease in the temperature inside the blast...
The progressive decarbonization of the steel industry is being undertaken through the transformation of Blast Furnaces (BF) and by limiting the quantity of coke.
The reduction of coke rates may impact the permeability at the Cohesive Zone (CZ) level, a viscous and impermeable layer resulting from the softening and melting of Iron Ore. The control of this CZ, its shape, thickness, and...
