\u00a0Have you ever wondered how the\u00a0TMT BARS<\/a>\u00a0used the construction of all the edifices that we are in are manufactured? This was something that I have always wondered about. The fact is that many of us are actually curious about how many things around us are manufactured, yet we don\u2019t make the effort to actually understand how it\u2019s all done. TMT steel bars have a crucial role in the construction industry. In this blog let\u2019s briefly go through the manufacturing process of TMT steel bars.<\/p>\n


<\/p>\n

Firstly, TMT stands for Thermo Mechanically Treated bars. The TMT bars are distinguished for their two layers of the core which is well known as the\u00a0OUTER HARDCORE<\/em>\u00a0and the\u00a0INNER SOFTCORE<\/em>. This unique property makes them robust and sturdy and enables them to last a lifetime.<\/p>\n

\u00a0The quality of the\u00a0TMT bars<\/a><\/strong>\u00a0depends on various factors like the raw materials used, the technology and machinery used for quenching and self tampering processes and finally the ability of the rolling mill- which gives shape to the material.<\/p>\n

\n

Lets now dive into the industrial processes involved in the production.<\/p>\n

    \n
  1. EXTRACTION OF RAW MATERIAL AND SHAPING THEM INTO REINFORCED BARS.<\/em><\/li>\n<\/ol>\n

    Firstly the raw materials such as coke, iron ore, dolomite, and limestone are put into a blast furnace and are treated with hot gases in order to achieve a molten liquid-like state. This is then pre-heated and is converted into steel. Steel and its chemical composition still need to undergo refinement during this stage, for which they are refined by passing through ladle heating. The materials are in their molten state, which can now be easily cast into any desired shape and size by just pouring them into the casting machine. The molten steel is heated up to 1250 degrees Celsius to reach the required shape and is then rolled in a rolling mill to structure them into reinforced bars.<\/p>\n

      \n
    1. QUENCHING<\/em><\/li>\n<\/ol>\n

      The heated steel bars are left to cool down or quenched by a rapid cooling process, which ensures that the purity of the metal stays intact and avoids the accumulation of any kind of undesirable properties. The rapid cooling of steel is known as the quenching of reinforced steel bars. Quenching helps in the prevention of the steel forming into a crystalline structure. Quenching reduces the time frame in which the material is thermodynamically favorable towards attaining any undesirable structure such as crystallization of the material.<\/p>\n

        \n
      1. SELF TEMPERING<\/em><\/li>\n<\/ol>\n

        Self tempering helps in the structure of the TMT bars. After quenching the material cools down. The core of the bar remains at a higher temperature than the surface. Thus the heat is transferred from the core to the surface of the bar. This results in the outer structure being tempered. This self-tempering process causes the formation of a ring made out of martensite and bainite, thus forming a tempered martensite outer surface.<\/p>\n

        4 .ATMOSPHERIC COOLING<\/em><\/p>\n

        \u00a0<\/em>\u00a0Finally, we have reached the final stage in the production of the TMT bars.\u00a0 As the title suggests this is the cooling stage. The bars are laid out on a cooling bed at normal temperatures to cool down. This is done to uniform the differences of heat between the core and the outer surface. After reaching the normal temperatures, the core attains a ferrite-pearlite structure. Atmospheric cooling makes the TMT bars more ductile and weldable.<\/p>\n
