PRODUCTION PROCESS

BILLETS

The steel billet in the product is obtained by casting the molten steel produced by the steelmaking furnace. To manufacture mild steel billets, sponge iron, ferroalloys, and other ingredients are charged into an electric arc furnace with lime in the required ratio for the targeted grade. In the arc furnace, the charged material melts at about 1800°C. When the metal comes out in the liquid form, proper refining is done, reducing impurities in steel such as sulphur and phosphorous. Samples are drawn from the liquid metal to ensure the proper chemical properties required are present.

At the end of the refining stage, the temperature is measured, and slag is removed from the furnace. After reaching the required temperature and chemical composition, the final tapping is done for the continuous casting process. Continuous casting is the process in which molten steel is solidified into a billet. Once the billets are ready, they are sent for further inspection. After the completion of a thorough physical inspection, the materials are made available for dispatch.
