A slab is a length of metal that is rectangular in cross-section. The slab is created directly by continuous casting or indirectly by rolling an ingot on a slabbing mill. Slabs are usually further processed via flat rolling, skelping, and pipe rolling. Common final products include sheet metal, plates, strip metal, pipes, and tubes.
A billet is a length of metal that has a round or square cross-section, with an area less than 36 in2 (230 cm2). Billets are created directly via continuous casting or extrusion or indirectly via hot rolling an ingot or bloom. Billets are further processed via profile rolling and drawing. Final products include bar stock and wire.
Billets after reheating and passing through the Descaler unit are rolled in a State of the art continuous rolling mill at high speed where stands are placed in H-V combination and are finished at Fast Finishing Blocks to get Uniform cross-section with better dimensional accuracies throughout the length.
Hot rolled from steel billet, wire rod is delivered as coil, most commonly at 5.5mm dia, but in sizes up to 60mm diameter. Close control of final cooling is a critical part of the production. The most important characteristic for determining a rod's end-use is its draw ability; the extent to which the rod's diameter can be reduced during the drawing process.
Hot rolled coil is rolled on a hot strip mill from slabs. It can be found in the market in coil or sheet form and is further processed into finished products by the manufacturer. Hot rolled coil is typically 2-25mm thick and up to 2,250mm wide.
Hot Briquetted Iron (HBI) is a relatively new product, developed in the past 25 years, as a supplement for pig iron and scrap in electric furnace steel mills. It is a compacted form of direct reduced iron (DRI), which facilitates its handling, storage, and use.
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
