Billets (MS & CRS) Manufatuer in India

Billets are semi-finished casting steel considered to be one of the best raw materials for producing high-quality steel bars and structural products. Billets undergo a series of manufacturing processes to be converted into a variety of finished steel goods, suitable to be used for various purposes. Billets are extensively used in forge shops and machine shops for the production of engineering goods, or feedstock in the rolling and other metal-processing operations.

Billets are produced with various grades and variants such as Mild Steel, Alloy Steel, Special Steel, Corrosion Resistance Steel etc. MS Billets confirmed to IS 2830:2012 are widely used for the production of construction steel QST bars.

At Shakambhari, the raw materials required for the manufacturing of MS Billets such as – Sponge Pellet or Sponge Iron are produced in-house. The quality control process of raw materials results in the production of the best quality of Billets. Shakambhari has integrated steel plants that produce a wide range of continuously casted billets employing world-class technology. Billets produced are mostly captively consumed as a raw material feed to our Rolling Mills manufacturing QST bars & Wire Rods. Shakambhari also has a niche export market for its high-quality Billets.

TMT Bar Application Areas

Different projects call for different types of TMT bars depending on the compositional strength, dimensions and features. Available in multiple variations, Elegant QST bars are used by reputed construction and developer firms across residential, commercial, industrial as well as infrastructure sectors. Given their ability to provide optimum strength, safety and durability to the structure, TMT bars are used for critical civil construction purposes such as power plants, dams, long-span bridges & flyovers, roads & highways, underground structures & underwater or marine structures, oil refineries and so on which are produced by TMT bar manufacturers in Kolkata. Apart from these, QST bars are also used in high-rise buildings, malls, schools, airports, hospitals and other large structures.

QST bars are extremely important and often used in earthquake-prone areas since their high bendability/elongation property can protect the structure from being uprooted. Elegant TMT bars are the perfect choice for corrosion-prone areas as the tough outer layer prevents rust, which is often responsible for causing cracks in the structure. Be it a residential building, hospital or any other construction – no structure can skip the risk of being exposed to fire. Being fire-resistant with high heat-withstanding capacity with Reinforcement Steel, Elegant QST bars can be used for all types of construction purposes.

M.S Billet USP

  • Shakambhari maintains stringent quality checks to produce world-class quality MS & CRS Billets conforming to IS 2830:2012.
  • State-of-the-art equipment and modern testing apparatus at our laboratories allow the continuous quality monitoring of production. Chemical analysis is carried out through Spectrometer during melting and at the final stage to assure consistent chemical composition of Billets.
  • After casting, Billets are carried out through the physical dimension tolerance test, Sulphur print test, Bend test and Camber test to ensure zero-defect Billets.
  • At Shakambhari, the raw materials required for the manufacturing of MS & CRS Billets are mostly produced in-house, ensuring superior and consistent quality.
  • Shakambhari has received certification from the Bureau of Indian Standards (BIS) for the production of Carbon Steel Cast Billet Ingots, Billets, Blooms & slabs. The main defining factor of the product is its chemical composition which we follow as per IS 2830:2012 standard.
  • Shakambhari billets are used for captive rolling of QST Bars and Wire rods, as well as also being exported to niche markets worldwide, due to preference for its high quality.

Manufacturing Process

QST or TMT stands for Quenched and Self-Tempered steel rebars fabricated by a quick cooling process called quenching and self-reheating of hot-rolled steel bars. The manufacturing process of Elegant QST bars usually involves 3 essential steps –

  • Quenching
  • Self-tempering
  • Atmospheric cooling

The Process

  1. The raw materials such as iron ore, coal, dolomite etc. are piled, recovered and mixed in required proportion and converted into metallic iron.
  2. The primary construction steel making process begins with the conversion of metallic iron to crude steel through electric heating and refining and after refined steel is brought to the continuous casting machine to solidify into rectangular cuboid called billets/blooms.
  3. Hot billets are rolled through thermomechanical treatment in fully automatic rolling mill, processed through quenching and self-tempering system and finally, rested for atmospheric cooling to produce the world class quality QST bars.
  4. The stringent quality checks are carried out through in line production and final products are tested for chemical, mechanical and physical properties. Batch identification is attached to each lot.

From procurement of the raw material to the manufacturing of TMT bars and dispatch of the final product, the entire process takes place in our integrated steel plant, which allows us to produce the best quality TMT bars.
