Iron pellets are small balls of iron ore used in steel production. Iron ores undergo a pelletizing process that combines mixing of raw materials, forming the pellet and thermal treatment baking. The process converts soft raw pellets into hardened balls of approx. 8 to 16mm diameters that are uniform in size and used as feed in Blast Furnace, Electric Arc furnace or DRI plant.
Iron pellets usually have high porosity which makes the reduction process quicker in the blast furnace. The spherical shape and open pores offer greater permeability which results in easy furnace operations. High pellet strength offers greater resistance when it comes to disintegration during the descent of burden.
Iron pellets are an integral component of steelmaking. From the construction of bridges to transport vehicles, planes, household appliances and many other infrastructures – steel is used in multiple industries and makes up much of the world around us. It has a great role to play in the advancement of developing nations which is continuously pushing the demand upwards.
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.
Pellets are a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of sponge iron and in blast furnaces for the production of hot metal. The iron pellets are produced with cold crushing strength (CCS) of 210+ and porosity of 24+” which helps to maintain grade in DRI fem – 80+ and our product mean particle size (MPS) is ~9.5-10 which assists in reducing oxygen in kiln and maintain consistency in grade. Iron Pellets are used as raw material for sponge iron and blast furnace.
Elegant can produce various grades/quality of pellet because of having rotary kiln where the pellets are heated and fired uniformly. The process can use multiple ores simultaneously by applying the art of raw material blending. Pellet process helps save energy i.e. power because of excellent heat recuperation and lower drop in pressure of gases. Apart from using items as input for our finished products.
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 –
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.
