Manufacturing Process

Iron making :

Iron making through DRI route using virgin iron ore lumps, coal, and dolomite through eco-friendly processes for producing high-quality sponge Iron.

Steel Making :

Sponge Iron produced through the DRI route is melted in induction furnaces with a small quantity of pig Iron and molten metal transferred to Ladle for De- phosphorization.


It is a process in which sulfur and phosphorous can be reduced to a lower level in the hot metal to produce High-Quality Billets through a Continuous Caster.

Rolling Process :

For consistently producing high-quality TMT bars we only adapt the Hot Charging route for the rolling mill. Once the billet reaches the desired temperature they are brought made to pass through the first stand of Rolling Mill. With this process of gradual size reduction of billet begins. Following Roughing mill the size is further reduced in the intermediate and Finishing Mill. This gradual reduction is an important factor to ensure the finer grain structure of the bar. The rolling continues till the required size is obtained.

Quenching Process (Thermax) :

In order to impart strength to the deformed bars, a controlled quenching process is performed. After leaving the last rolling stand rapid and controlled water quenching is done and temperature drops from 950ºC – 300ºC. Due to high speed only out position (Surface) of the bar gets converted into martensite. The microstructure is fire grained Ferrite –pearlite structure at the core.

Self-Tempering :

In a cooling bed, the core that is still hot transfers heats outside to the surface thereby tempering it. Due to self-tempering martensite becomes tempered martensite which has more strength and excellent corrosion resistance properties. Quenching as well as tempering leads to the typical microstructure of the Rebar.

Stocking TMTNEXT :

Finished bars are strapped and bundled automatically as per desired by customers and stocked safely in the stockyard.
