WELSPUN STEEL LIMITED

The process of sponge iron making aims to remove the oxygen from iron ore. The quality of sponge iron is primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio of metallic iron to the total iron present in the product. Sponge iron manufacture is highly sensitive to raw material characteristics.

Steel Wikipedia

Since the oxidation rate of iron increases rapidly beyond 800 °C (1,470 °F), it is important that smelting take place in a lowoxygen environment. Smelting, using carbon to reduce iron oxides, results in an alloy that retains too much carbon to be called steel. The excess carbon and other impurities are removed in a subsequent step.
