Manufacturing Process

The production of quality of TMT Bar depends on the raw material used, designs of the mill and the tempering technology.

Process Protocols

TMT Manufacturing engineers take great care developing process protocols that are quality-controlled, efficient and economical while satisfying the product performance requirements stipulated by our customers.

Steel Production

We produce steel from direct hot charging, a  process that also improves the product quality. In the hot charge technique for round rolling, billets are delivered for hot rolling in the Bar mill after that exit the CCM (Continuous Casting Machine)

The main features and advantages of the hot charging technique include:

  • Less overall energy consumption and greater cost control.
  • Decreased billet inventory and less use of yard space
  • Reduced production cycle time
  • Prevention of billet surface quality defects during the cooling process

Birla TMT’s superios prioducts lead the construction for three basic reasons:

High-quality raw materials

Manufacture in a modern state-of-the-art mill

Use of quenching and tempering technology in line with international standards and practices
Birla TMT Bars are the new generation bars produced through a highly advanced procedure using a state of the art plant in Himachal Pradesh

ach steel bar is passed through a post-modern water-cooling system to create a temperature gradient in the bars. The core is reheated and quenched by a conduction method that tempers the external martensite. The, the bar is taken out to cool, which leads to further cooling, attaining superior strength and toughness, tempering the austenitic core to ferrite and pearlite. Through this processing the bars comprise many layers, formed by different cooling stages, strong, tough, tempered martensite in the surface layer of the bar, an intermediate layer of martensite and bainite, and a highly useful ferrite and pearlite core. Birla TMT Bars are now a perfect fit for many construction projects. They are strong and equally flexible to meet today’s changing demands of the construction industry. Birla TMT bars have a hardened periphery of about 15 to 30 percent of the cross-sectional area, which makes it ideal for civil constructions.
