What is Bloom?Bloom: If the width of the billet is more than 15 cm (or the cross-section is more than 230 cm2), it is called bloom, and for this reason, usually these two products are in one category (Bloom and Billet)
What is an ingot?
The length of this product is less than 2 meters and its dimensions are optimized for transporting Steel and storing it. Its transverse cross-sectional shape is trapezoidal.
What is a billet?
unlike ingots, is long and its cross-sectional area is a circle or square with a width of less than 15 cm (or a cross-sectional area of fewer than 230 cm2). The billet is obtained by direct casting, extrusion (extrusion), or by rolling ingots. Billets are mostly used to produce rebars and wires.
What is Bloom?
Bloom: If the width of the billet is more than 15 cm (or the cross-section is more than 230 cm2), it is called bloom, and for this reason, usually these two products are in one category (Bloom and Billet). Bloom is used to making rails, beams, cans, studs, shields, and so on.
What is a slab?
Slab cross-section, unlike bloom and billet, is not square but rectangular (usually 230 mm thick, 1.25 m wide, and 12 mm long). Slabs are used to make steel sheets, plates, and so on.
Note: Today, the technologies used in manufacturing the steel products in the later stages of obtaining molten steel, i.e. casting and rolling, are more or less the same. But to obtain molten or crude steel, various technologies can be used, including blast furnace (BF), arc furnace (EAF), and induction furnace (IMF) methods. Although most of the crude steel production in the world is produced by the blast furnace method, for various reasons, the use of the electric furnace method, especially in Iran, is more justifiable.
