Talk:HIsarna ironmaking process - Wikipedia

Pig iron pellets. The "pellets" refer to an intermediate product of the steelmaking process used by Tata IJmuiden and other ULCOS partners. Before introducing iron to the blast furnace, they process raw ore into pig-iron/coal pellets. These pellets are very porous, which creates a large reactant surface of pig iron and coal for the hot air in ...
