Steel Making Process At Evonith Steel
Cooking Coal
Also known as metallurgical coal a raw material used to produce coke which is porous in nature and a form of pure carbon, which acts as both a fuel and reducing agent in the blast furnace.
Coke Oven
A recovery type state of art oven where coking coal is heated in the absence of air to form coke, which is rich in carbon.
Fluxes
Fluxes help to remove impurities and formation for slag.
Iron Ore Fines
Iron ore fines are basically iron oxide and are the main source of iron; both are pre-processed.
Blast Furnace
Sinter, coke, and fluxes are charged into the furnace; chemical reactions reduce iron ore to molten hot metal.
Pig Iron
A crude form of iron and use as raw material in steel making and in foundry
Hot Metal
Electric Arc
In EAF, hot metal along with scrap and DRI is melted using electrical energy/ use of oxygen blowing to start refining and converting into steel.
Ladle Refining Furnace
At LHF the steel quality is improve by process of de-sulfurizing and adding the required alloying element to achieve desired quality of steel before casting.
Slab Caster
The molten steel is continuously cast through the mould into rectangular slabs for further rolling.
Hot Strip Mill
Slabs are reheated and rolled into hot rolled (HR) coils and plates above recrystallization temperature.
HR Coil
Slabs are rolled in HSM to reduce the thickness and wound in coil form which is easy to form and having required metallurgical properties to us in various end use.
HR Slitter Slit Coil
Slits wide HR coils into narrow HR slit coils of required width for specific industry use.
HR Slit Coil
Used in tube making, structural applications, or as feed for other processes.
Coil Goes to
CRM Complex
CRM Complex
HR coils are fed into the Cold Rolling Mill (CRM) for further thinning and surface finish.
Coil Rolling Mill
Reduces thickness of HR Coils after pickling steel at room temperature to produce cold rolled (CR) coils.
HR CTL Coil
HR coil is straightened and cut into flat sheets of required length.
HR Sheet
Flat hot rolled sheets of required length used in construction, pressure vessels, etc.
CR Coil
Final cold rolled products available in coil and sheet form of required dimension.
CR Sheet
Final cold rolled products available in coil and sheet form of required dimension.
CRCA
(Cold Rolled Close Annealed) High-quality cold rolled and annealed steel used for automotive and appliance industries.
Bell Annealing
Heat treatment in a controlled atmosphere to soften the steel and relieve internal stresses and improve microstructure and mechanical properties.
CR Coil
Has a smoother surface and good dimensional accuracy, which is further use for galvanizing /Annealing process.
CR Coil Goes To
Galvanized Line
Galvanized Line
CR coil is sent to the galvanizing line where it is coated with zinc.
GP Coil
Zinc-coated steel coil which offers corrosion resistance and durability.
GP Sheet
Flat galvanized sheet having specific and required length used in ducting, roofing, or panelling.
Corrugation Line
GP sheets are passed through rollers to create the wavy pattern for strength.
Corrugated Sheet
Final product used extensively in roofing and cladding due to its durability and rust resistance.
