  • Development of Aceh iron sand to produce pig iron: studies

    A study has been carried out to develop of Banda Aceh iron sand to produce pig iron using reduction processes. Hardness tests and characterization of mineral were performed and the results are reported. The results show that the average hardness properties of both the sponge and the pig iron were 282, 22 HV and 377,178 HV, respectively. Chemical

  • US5238487A Process for the production of pig iron and

    A process for producing pig iron is described, which contains a reducing shaft furnace 1 and a melting gasifier 2. The sponge iron produced from iron ores in the reducing shaft furnace is supplied to the melting gasifier and converted there into a pig iron melt. The gas produced in the melting gasifier is supplied directly via a line 4 as reducing gas to the reducing shaft furnace.

  • Difference Between Sponge Iron and Pig Iron Compare the

    Apr 30, 2011· The key difference between sponge iron and pig iron is that we can produce sponge iron by direct reduction of iron ore through reducing agents whereas the production of pig iron is by melting iron ore with charcoal and limestone at very high pressures.. Sponge iron and pig iron are different forms of iron that we can produce from iron ores that occurs naturally under the surface of

  • Sponge Iron an overview ScienceDirect Topics

    DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H
