Manufacturing Process

Iron Making

Iron making through BF & DRI route using virgin iron ore lumps and fines mined through environment friendly processes.

Steel Making

State-of-the-art steel making technology using Blast Furnace(BF) + Direct-Reduced Iron(DRI) - Electric Arc Furnace(EAF) - Ladle Refining Furnace(LRF) - Continuous Casting Machine route producing clean steel billet, with very low levels of sulphur and phosphorous (less than 0.035%) and very low levels of inclusin and tramp elements.

Steel Rolling

World's most advanced Morgan Rolling Mill deploying HYQST technology, to produce TMT of consistently high quality finished with automatic cutting and packing.

  • Digital Furnace Reheating
    Walking Beam Type Digital Furnace, which ensures uniform heating but ensures less fuel consumption.
  • Secondary Descaler
    To ensure scale free rolling using high pressure jets at 230 bar.
  • Rolling (In Closed Boxes)
    12m long insulated roller table, which ensures rolling at a gap of 5 sec. Transports the processed sections, as a free bar, from Breakdown Mill to Continuous Mill. Minimizes temperature loss from head and tail end. Insulated cover helps to retain billet section's temperature.
  • No Twist Mill
    Continuous Rolling through alternate V-H Mill, which ensures a greater speed. Mill Train arrangement for proper rolling of finished sections. Bed assembly comprises of V-H bed assembly.
  • HYQST Controlled Quenching & Tempering
    Thermo-Mechanically Treated (TMT) Rebars involve a combination of plastic deformation of steel in austenitic stage followed by quenching and further self tempering in 90m long cooling bed.

QUENCHING
The hot rolled bar leaves the finishing mill stand at 1050° Celsius which is rapidly quenched in a water box. This is a chamber where water is made to impinge on the surface of the rebar at high pressure by split style nozzle with microprocessor based controlled cooling process. The quenching converts the TMT's surface layer to martensite and causes it to shrink. The shrinkage pressurizes the core helping to form the correct crystal structures, while the core remains hot and austenitic.

SELF-TEMPERING
The bar leaves the quench box with a temperature gradient through its cross-section, and as the bar cools, heat flows from the bar's centre to its surface so that the bar's heat and pressure correctly tempers an intermediate ring of martensite and bainite.

ATMOSPHERIC COOLING
Finally, the slow cooling after quenching automatically tempers the austenitic core to ferrite and pearlite on the cooling bed, which now has a strong and tough, tempered martensite on the surface layer of the bar: an intermediate layer of tough martensite and bainite and a refined, ductile ferrite and pearlite core.

AUTOMATIC STRAPPING & BUNDLE
Online controlling of length of final bar bundles as desired by customers.
