Ingot, Billet and Slab

Scrap and used irons are poured into Electric arc furnaces in special baskets and then sponge iron is added to it with slag materials such as coke, lime, bentonite, etc. from above. The charge of the furnace is melted by the heat generated by electric arcs.

After the separation of impurities, the molten steel is taken to the casting unit by means of trays carrying the molten material. The molten material is poured into a container, then it is placed in a round copper mold and placed on a roller, and it is cooled by sprinkling water. Then, the obtained frozen ingots are cut to the desired lengths.

Eisen Group has ability to provide the following items with the best quality according to customer’s demand and the lowest price as soon as possible.

Ingot:
The ingot has a trapezoidal surface with a maximum length of 2 m in each branch. The appearance of the bars makes them easy to transport.

Billet:
The billet is longer than the ingot and has a circular or square surface with a width of less than 15 cm or a cross-sectional area of less than 230 cm.

Bloom:
Bloom is actually the same as billet but more than 15cm wide, the cross section is larger than 230 cm, so Bloom and Billet are usually grouped together. Most of Bloom’s uses are for rails, cans and beams.

Slab:
Unlike Bilt and Bloom, the surface of the slab is rectangular and is usually 230 mm thick,
1.25 m wide and 12 m long. Slabs are the raw materials for making steel sheets.
