In a blast furnace, iron ore (in the shape of sinter) and coke are converted into liquid hot metal at a high temperature. We have 2 blast furnaces, referred to as blast furnace A and blast furnace B, which serve as the heart of our production site. Blast furnaces operate for 20 to 25 years after which the refractory lining has to be renewed.

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.
