Use of Iron Ore Pellets in Blast Furnace Burden IspatGuru

Jun 13, 2014 Iron ore pellet can be used as a substitute to sinter and calibrated lump ore in the blast furnace burden due to the following properties. Spherical shape and open pores of pellets gives better and uniform permeability resulting in smoother furnace operation. Pellets have a uniform size range generally within a range of 8 20 mm.

Sintering: A Step Between Mining Iron Ore and Steelmaking

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
