TMT or Thermo Mechanically Treated bars have brought in a revolution in the construction industry which is right in all ways. The Tmt Bars turn out to be the primary choice of builders because of their high durability, better ductility than other Steel bars, and lastly for being amazingly cost-savvy. One can easily afford TMT bars for construction. Steel manufacturers are using the latest innovative techniques to produces the best quality steel TMT bars so that they cater to the growing need of the construction market. These bars are not only economically cheaper but also are more durable in strength. Making an ideal choice for construction. TMT bars have got a huge fan base.
Several Steel manufacturers in the market are using the special kind of thermomechanical process in creating these affordable TMT bars. The TMT bars come with anti-corrosive properties which can be traced to their very manufacturing. The special thermomechanical process caters to the production of premium quality steel that has an exceptional Ferrite-Pearlite core encased in Tempered Martensite. The steel producers make sure that they don’t compromise on imparting the best quality product at the price they are offering to the buyers. The TMT steel bars go through the following steps before reaching your site all set for construction.
- Materials Sourcing and Processing: The first step for manufacturing TMT steel rod is sourcing out steel and stack them in an Induction Furnace. Induction Furnace is highly efficient because of giving out low capital cost as compared to other furnacing techniques. The molten metal is easily circulated in an Induction Furnace using the electromagnetic action so that a homogenous compound is extracted in minimum time. For creating TMT bars various products are added or removed from the contents to give out the desired resultant compound. For the above step different processes like Ladle Furnace, Ladle Injection, Degassing, CAS-OB, etc. are used.
- Steel Billets Manufacturing: After attaining the optimum temperature and chemical composition the molten steel is then poured into the pre-heated ladle. The ladle is used for casting the steel into billets. Once the machine is ready for casting the molten steel, the ladle is opened from the bottom, operated by a hydraulic machine, into a Tundish. The steel is taken from the Tundish into two strands which contains the molds of required sizes. As soon as the molten steel cools down, it takes the shape of the mold on solidification. These casted billets are then cut into length and send to the rolling machine for the formation of the steel rods.
- Production of Steel rebars from steel billets: The final manufacturing takes place in the rolling mills which consist of three separate units. The three separate units produce three different sizes or diameters of TMT bars.
- Roughing Mill
- Intermediate Mill
- Finishing Mill
After the hot rolled bar comes out of the finishing stand, the bars are passed through sprays of water. Water cools down the temperature of the molded steel bars and fast solidifying of the rebars. With the special ‘self-tempering ’feature, the core heat is transferred all across the external surface. Then the bars are shifted to cooling beds to minimize their temperature automatically.
ARS Steel is one of the leading steel manufactures in India. Being one of the most preferred choices of the builders, ARS Steel produces the finest quality of TMT bars that are highly affordable and durable at the same time.
