Production Facilities

Krakatau Steel has 6 (six) production plants making the company as the only integrated steel plant in the country. These plants produce many kinds of downstream products from upstream raw materials.

Production processes of steel products in Krakatau Steel starts from Direct Reduction Plant. This plant processes iron ore pellets into irons using natural gas and water.

The irons are then fed into electric arc furnaces in Slab Steel Plant and Billet Steel Plant. In these furnaces, the irons are mixed with scrap, hot bricket iron, and other additional materials to produce two kinds of steels, namely slab steels and billet steels.

Slab steels are then reheated and rolled in Hot Strip Mill becoming hot rolled coils and plates. The outcomes of this mill are widely used for ship buildings, pipes, buildings, general structures, and other applications. Furthermore, hot rolled coils could be processed, re-rolled, and chemically treated in Cold Rolling Mill becoming cold rolled coils and sheets. The results are generally used to manufacture car bodies, cans, cooking wares, and other applications.

Billet steels are rolled in Wire Rod Mill to fabricate wire rods which are commonly used for piano wires, bolts and nuts, steel cords, springs, and other applications. [2]
