How are Steel and TMT Bars Produced?
Steel is the main material that is used for the purpose of construction, and is an alloy of carbon, iron and various other materials. It comprises of around 0.2% carbon in terms of weight. This metal is used widely for making automobiles, ships, tools, machines, buildings and much more. The process of steel construction was commercialized as early as during the later part of the 1800s.The metal has a widespread usage, given that it boasts of very superior strength-to-weight ratio, durability, tensile strength etc as compared to other construction materials.
Steel Forming
This is a technique that transforms solidified steel into the types of shapes that are regarded as ideal for construction and fabrication industries. This process improves the physical properties of steel, thus making is perfect for most applications. This process is used to create plates, rods, bars, billets and various other products.
Steelmaking
This is the second step in steel production from iron ore. In such a stage, phosphorus, sulfur, excess carbon and other impurities are taken out of raw iron. After that, alloying elements such as vanadium, chromium, manganese and nickel are added in order to manufacture the kind of steel that is desired.
The modern process of steel production has been categorized into two types:
- Primary Steelmaking - In this process, molten pig iron that is high in carbon is prepared in the blast furnace and is transformed into steel. Then, oxygen is blown via the molten pig iron in order to reduce the amount of carbon within the alloy and transform it to low-carbon steel.
- Secondary Steelmaking - This process involves melting scrap metals in a large furnace. However, it must be remembered that even this technique consumes a lot of energy, much more than is involved in the production of primary steel. The steel that is obtained after the process of purification is debased.
The steel making process results in making steel of high grade, such as strong TMT steel bars that are Thermo-mechanically Treated as well as mild steel bars. It is possible to get TMT bars in various grades, such as Fe 600, 550, 500 and 415.
For primary steelmaking, Iron ore is the material used as a feedstock. Scrap steel, on the other hand, is used for secondary steelmaking as the main raw material. Steel is subjected to a number of processes to improve its properties, such as hardness, ductility, yield strength, corrosion resistance, mechanical strength and more.
