The reason why UMA 550 TMT Bars deliver in quality lies in its well-planned and efficient production process. Here is how we produce one of the high-quality steel bars of not only Jalna region of Maharashtra but also of India.
UMA 550 TMT Bars
Here is the thorough process we carry out to produce TMT Bars
Feeding
Procured MS Billets are checked for the quality and, upon satisfaction, fed to the re-heating furnace by a crane.
Re-heating Furnace
Rolling division is equipped with a gas fired furnace. This furnace is supported by a Palwalejer, one of the best in the industry. The Palwalejer runs on coal and other biomass fuels, hence it is not only an eco- friendly way of heating the furnace, but also a cost effective way as the costs of petroleum and other fuels are ever rising. making us one of the largest producers of steel bars/TMT Bars in the Jalna region of Maharashtra. The furnace is supported by a technology that analyzes the gas fuel automatically as well as adjusts the temperature to maintain it ideally. This re-heating furnace has been designed especially for MS Billets. Hence it is not possible to feed it with ingots or any other inferior raw material.
Roughing Mill
The heated steel is fed to the roughing mill. Our roughing 18 3-High mills are capable of consuming MS Billets from 125 X 125 mm. Operating at 12 HP, this roughing mills can roll billets from 159 KG to 950 KG. Passing through several narrow passes, the billets are turned into steel bars.
16`` Intermediate Mill
The hot and elongated steel bar passes to the 16 Intermediate Mill. It rolls over the bearing-operated stand, which operates on a 450 DC Motor. Here the bar further elongates.
14`` Intermediate Mill
The hot and elongated steel bar passes to the 14 Intermediate Mill. It rolls over the bearing-operated stand, which operates on a 330 DC Motor. Here the bar further elongates.
12`` Intermediate Mill
This intermediate mill with two cross-country stands reduces the diameter of the steel bar and further elongates it. Every bearing operated stand is powered by a 330 HP DC Motor.
Finishing Mill
Operated with 8 stands, the DC motor powered finishing mill ensures that the steel bar is consistently weighs and sizes over its entire length
Quenching and Self Tempering System
Every 8 MM bar passes at 20 mm per second to the TMT Quenching System (QST). This world class technology cools down the bar at a sudden rate by spraying a mixture of airand water.The external temperature of the bar suddenly drops down from 10000 to 4000. Then, as the bar exits the TMT Quenching System, the temperature from its core spreads out re-heating the bar to around 600 0. This ensures that while the bar remains soft at the core it toughens up from the outside, flexible from inside and strong from outside achieving high strength and high ductility. Our TMT Quenching System has been worked upon and improved into a Double Quenching Box, which ensures that the quenching happens at the right speed ensuring consistent quality throughout the length of the steel bar. This generates a better microstructure in the steel bar. The fly shears resent in this system cut the steel bars in desired length.
Cooling Bed
Our two cooling bed, For both mill independently 5 meters X 78 meters in length is made of finest steel, which ensures that the freshly produced and still hot bars are handled delicately so as not to harm them with dents or any sort of inconsistency in shape and straightness. This automated cooling bed collets all the produced TMT bars by itself, not requiring any manual intervention to ensure high quality.
Finished Goods Yard
Our weather-controlled, closed shed finished goods yard of 5500 Sq. meters ensures rust free steel bars which can be quickly delivered with the help of in-house EOT cranes.
