Ferro Alloys

Ferro Alloys play a crucial role in steel production and defining their quality. They are used as deoxidisers and improve the properties of steel. Ferroalloys refer to one or more specific alloying elements employed in desirable quantities with iron in the most feasible technical and economic way. The principal Ferro Alloys include silicon, manganese, chromium, titanium etc. At Shakambhari, we manufacture different variants (Grades) of Ferro Alloys like Ferro Manganese, Silico Manganese, Ferrochrome, Ferro Silicon and so on.

Since the quality of raw material plays a major role in the smooth operation of the production process, we take utmost carewhile manufacturing Ferro Alloys. At Shakambhari, we procure the raw materials from credible sources – either directly from registered mines in India such as MOIL, AMTC etc. or import from overseas. The primary application of Ferro Alloys occurs in steel making process since they contribute to improved corrosion resistance, tensile strength and higher ductility at high temperatures. From melting to casting – the influence of Ferro Alloys is important in different stages of the steelmaking process.

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.

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.
