Ingots are produced in induction furnace using either sponge iron or scrap. At SEML, we use our captive sponge iron to manufacture steel ingots. This gives us an edge over our competitors as we are in complete control of our raw material as well as finished product quality. Induction furnace provides a clean, energy - efficient and highly controlled process as compared to most other means of steel melting. The steel is molted by inductive heating of the metal in a crucible. After it is refined, the molten steel is tapped into refractory lined ladles. The molten steel is then poured into a series of ingots molds. After the ingots solidify, the ingot molds are placed in soaking pits for heating and to equalize the internal and external temperature. Following the soak, the ingots are hot rolled in large primary rolling mills to produce slabs, blooms, or billets depending on the final product desired. SEML has a total ingot production capacity of 40, 000 MTPA. Specification specification is as under
