Steel Making in Progress In TMT Bars, the Process of manufacturing has its own importance.
The steelmaking process requires primary steel for the converter process. In this process, iron ore is converted into steel. This process uses pig iron from the blast furnace. Primary steelmaking has two methods: BOF (basic oxygen furnace) and the more modern EAF (electric arc furnace) methods. Secondary steel is usually made after adding some alloying elements to primary steel. This steel is made by melting scrap or sponge iron and sometimes a mixture of both using the induction route. Later in the article, we explain in detail the difference between these two manufacturing processes. Before that, let’s understand if there are any standards imposed on them. As these are standardized products, that would make understanding easier for retail customers.
- A TMT Bars should bend smoothly when bending activity is conducted.
- Transverse ribs or lugs of the bar should be sharp enough to create a strong bond with the cement.
- Do not use any TMT bar that is made using scrap as it does not guarantee endurance to heavy loads.
- Before purchasing rebars, one should crosscheck prices. Leading and reputed TMT rebar companies publish their prices in the public domain,
including their websites. Check these before buying a top TMT Bars from a primary or secondary producer.
- The comparable weight of bar per meter should adhere to ISI standards. Cross-check this when you weigh the bar.
- The bar should be of an ISI or ISO 9001:2008 certified company.
- Every meter length of the bar should bear the company’s stamp.
- Every bundle should carry the company’s seal on it.
- Apart from providing steps for scrutiny, we are also carrying out the most important test, BIS 1786, on TMT samples of the difference.
