Anwar Ispat has been pioneering the rolling industry of Bangladesh for around half a century. They were the first to introduce 60-grade products in the mild steel market of Bangladesh and ever since that they continue to set the standards in the Bangladesh market through the implementation of cutting-edge technology. Anwar Ispat has been bridging the gap between Bangladesh and its foreign counterparts by introducing technological sophistication used globally. This includes the introduction of patented equipment from countries like the USA and Belgium. With its relentless dedication, Anwar Ispat has been catering to the needs of Bangladesh while also successfully penetrating the export market. ICE Business times witnessed the intricate production process that accounts for Anwar Ispat’s world-class billets and bars.
The next step involves feeding the scrap into the furnace. The furnace can reach temperatures up to 1600 degrees.
The whole process can be divided into two broad categories Manufacturing the Billets and Rolling. Rolling is the process through which the billets are transformed to TMT bars, the finished good. This step involves groove cutting done by CNC large machines which accounts for the patterns seen on the rods and also notching done by CNC notching machines which account for branding the rods with the company logo. One thing to note that these machines are adjustable to multiple plates that cater to the groove cutting and notching of rods with varying diameters.
Quality testing has experienced a lot of sophistication over the years. The spectrometer is one such marvel, it can analyze a sample and tell the percentage of the 28 elements present in it in a matter of seconds.
Deficiency of key elements in the billets is mitigated by the use of various sponges, ex: Iron sponge for iron deficiency. If any element is present in excess, various chemicals are used to bring it to levels accepted by the standards.
The semi-finished TMT bars that reach temperatures excess of 900 degrees Centigrade are then passed through 18 continues where they receive Thermomechanical Treatment (TMT) which helps the temperature to gradually decreased to zero.
As soon as all the aforementioned steps have been taken care of, the bars are then cut to 12m each (as per customer requirement) and then taken away to the storage facility to be delivered.
