MANUFACTURING

Molten metal from the ladle refining furnace is poured into a nearby tundish, which then pours the liquid into a mold located underneath. This process is used to cast a predetermined length of metal, transforming the molten metal mix into a solidified form. New molten metal is continuously supplied to the mold at a precise rate to keep up with the solidifying process.

Our advanced continuous casting machine helps in achieving improved yield, cost efficiency, productivity, and quality.

Once the solidifying billets exit the continuous casting machine, they enter a secondary cooling chamber. Here, the semi-finished billets are sprayed with water to achieve complete solidification. This process is important for maintaining the shape of the solidified billets, improving their quality in the long run.

Next, the solidified metal strands are reheated again in our reheating furnace. This is done to recrystallize the metal, improving quality and reducing material losses. The recrystallization process is very important because the metal strands can then be processed in the rolling mill without destroying the bonding

The recrystallized metal billets are transported to a cutting-edge rolling mill using conveyors. Here, they are processed using the internationally accepted roll pass design, which makes for higher strength and elongation. This fully automatic process ensures a greater degree of uniformity throughout the length of each bar.

Our state-of-the-art rolling mill technology comprises a roughing mill of two 18” stands, four intermediate mills, four pre-finishing mills, and a finishing mill of six 12” stands. All the stands have individual DC motors to maintain total automation.

After the steel rebars leave the finishing mill with the desired size, they enter a water cooling chamber where they're subjected to a quenching process. We have an Evcon Turbo machine which employs a unique method for quenching and self-tempering the ribbed steel bars. This treatment is completed in 3 successive stages:

♦ As soon as the steel rebars leave the final mill stand, they are rapidly cooled to ensure surface hardening.
♦ Once the quenching operation is completed, the surface layer of each bar undergoes a tempering process with the help of the residual heat left in its core.
♦ The third stage takes place when the steel bars lie on a cooling bed, where they are are subjected to rapid air cooling.

Due to this extensive process, each of our steel bars have greater strength, ductility, bendability and weldability.

The Thus produced TMT BARS are master Bended and nicely packed according to the requirement of the consumer for space constrains.

TMT bars made through this process are then sent to specially arranged labs to test the quality and strength by suing the right chemical composition of F500 grade set by BIS. Also, the sectional weight and strength of each unit of TMT bar is tested every 30 minutes to give customers the best ever.

SIRI TMT bars have precise, uniform and parallel rib pattern engraved through computer controlled notch making machines, which results in excellent bond strength with concrete. The right combination of chemicals in SIRI TMT bars ensure easier and faster welding without pre-heating. This means stronger and safer weld joints and reduction in wastage during welding at the site.SIRI TMT bars are proven to have a higher resistance to cyclic loading conditions and are recommended in earthquake prone areas due to their superior seismic resistant properties. Due to the highly controlled process that ensures a microstructure with a soft core, SIRI TMT bars have excellent bendability, making work easier and faster at construction sites.

We understand the needs of our clients in the best manner possible. We know that delays in steel supplies to their construction sites result in increased losses. That’s why we have a large pool of reliable transporters who we work with closely to ensure that the material reaches your site on time.
