HOW A BLAST FURNACE WORKS - Foundry Gate

2018-7-10  Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2O 3) or Magnetite (Fe 3O 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into
