HOW A BLAST FURNACE WORKS

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 05 to 15 inch 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...

THE BLAST FURNACE

Blast furnaces are used continuously and are only shut down when their brick lining needs replacing As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron...
