Manufacturing:

Radha TMT bars are manufactured using Sponge Iron to ensure the highest grade of purity and lowest sulfur and phosphorus content. Consistent chemical composition and zero residual stress in the TMT bars increase the ductility and load-carrying capacity of our bars.

Radha TMT Steel Bars undergo a specialized 3-stage manufacturing process involving Thermo- Mechanical Treatment which is at par with global standards.

STAGE 1

The rolled bars are subjected to a specially designed water-cooling system which renders the outer surface of the bars cold while retaining the heat within the core

STAGE 2

The heat from the core of the bar dissipates to the surface creating a temperature gradient in the bars forming Martensitic on the surface while retaining the Ferrite, Pearlite structure at the core. This process is called ‘Self-tempering’ of Radha TMT bars.’

STAGE 3

The unique combination of Ferrite, Pearlite at the center and Martensitic on the surface gives Radha TMT steel bars a higher yield strength coupled with higher elongation and finer ductility.

Technology that gives us strength

LADDLE REFINING FURNACE (LRF)

LRF is used to improve the quality of liquid steel through refining, chemistry adjustment, inclusion modifications, etc. Additional heat is required to carry out these operations. Hence the ladle is provided with a heat source that heats the liquid metal and compensates for thermal losses.

INSIDE THE LADLE REFINING FURNACE

Steel is De-sulphurised and De-phosphorised to meet the stringent quality requirement of TMT bars. Dissolved gases in the steel are lowered through mild purging of inert gases and the metal is also homogenized. Inclusions are removed or altered chemically to ensure high quality of steel.

THERMEX TECHNOLOGY

This denotes a Quenching and Self-Tempering technology, also called QST which was developed by HSE Germany after years of research and field trials. Under this technology, the bars are toughened through Quenching and Self Tempering to ensure uniform quality across the bar.

On further cooling of the bar in the atmosphere, a Thermal Exchange (THERMEX) occurs between the inner and cooled outside Martensite surface whereby the resultant bar structure is a distinct tempered Martensite at the periphery and a fine-grained Ferrite-Pearlite structure in the central zone.

This unique combination of Ferrite-Pearlite at the center and Martensite on the surface gives both strength and flexibility to the bars.
