Blast furnace plant
5.2 million tons of pig iron
The two large blast furnaces produce up to 5.2 million tons of pig iron annually with a mix of sinter, pellets and flux, which provide for a correct composition of the flux and basicity.

Coke, coke powder and oil are used as a reducing agents. By injecting hot air with temperatures of 1300 °C the ferric oxides are reduced to iron and the accompanying elements transferred into the slag. With every one of the approx. eight tappings per day per blast furnace, the pig iron is poured over a flow system into open ladles, which are then transported by rail to the steel plant.
With the reduction of the ferric oxide to iron the reactions are complicated and mutually interact.
Casting hall dust removal
)
The gases developed during the tapping of the blast furnaces in the casting halls are extracted and cleaned by effective dust extraction installations. Since our system requires extraordinarily little energy it was used a model for further plants, which Mannesmann Demag have used to build a series of steel plants.
