                                                      PIG IRON

                 ig iron is an intermediary product when iron ore is smelted with a fuel with high carbon, such as coke.
                 This is usually done with limestone to act as the flux. Anthracite as well as charcoal can be utilized as
           Pfuel as well.
           It has a fairly high carbon content combined with silica and dross constituents, making it very brittle. Pig iron
           should not be directly utilized as a material with the exception of some limited applications.
           Pig iron is produced in the blast furnace sector. The raw materials used include ore, sinter, coke, lime and
           various aggregates.
           To ensure that the production process maintains a high and stable level of quality, these materials have to be
           metered precisely and supplied to the blast furnace in batches.
