Steel Production Technology | Metallurgy for Dummies

Sinter plant. The iron feedstock of the blast furnace is the sinter, which is produced in the sinter plant. In the sinter process, a mix of iron ore fines, lime and coke (almost pure carbon) is charged in a 45 cm thick layer onto a moving conveyor (Dwight Lloyd process) and partially melted to form a porous mixture of iron oxides and gangue.
