ABSTRACT ： Hlsarna is a new coal-based smelting-reduction technology for

ironmaking. Its benefits include: process intensification and energy efficiency; ready

for Carbon Capture Usage or Storage (CCU/S) process gas; reduced emissions of dust,

SOx, and NOx; flexibility in raw materials; and increased circularity through

reclaiming Zn from waste materials and/or Zn-coated scrap. Because Hlsarna

produces low-phosphorus and low-silicon hot metal, it reduces costs in steelmaking
ᇏݓࣁඋ࿐߶
and opens opportunities for new products. The process also offers lower capex and

opex compared to the blast furnace route. The Hlsama process has the potential to

replace a substantial part of the injected coal by biomass, natural gas or hydrogen.
