The Melting Shop used by Sotrafer for the production of standard mild steel grade is equipped with a 12-ton UHP Furnace (Electrotherm) and an AOD converter with a 15-ton capacity. The Casting process carries out through a continuous casting machine in square billet 100 MM². The Billet is ground and inspected to eliminate all the surface defects due to casting operations. Online, the hot rolling process is performed in a fully automatic bar mill under SABS Standards consisting Re-heating furnace, roughing mill stands, intermediate mill stands, and a continuous mill, capable of producing bars from 6 mm to 32 mm. Thermo-mechanical treatment (TMT) process gives the final surface aspect and mechanical characteristics to TMT Bar which ultimately, as a Produce introduced to the market as (SOTRA TMT).
Over the course of more than 25 years of hard work with many large and small projects. We have worked out the best working process.
The salient features of the rolling mill include an extensive Billet / ingot yard for stacking of Billet / ingot, reheating furnace, Roughing mill, Intermediate mill & finishing mill, continuous shear to cut finished TMT bars, besides the most modern TMT facilities.
This technology is introduced by “SSS” Technologies. A contemporary technology, it allows the production of bars to be on par with SABS standards. Hot rolled from steel Billet / ingot and subjected to PLC-controlled online thermo-mechanical treatment, the bars are made to pass through heat treatment over four successive stages.
