  • A Look at the Process of Pelletizing Iron Ore for Steel

    Below is a look at this critical process Preparing Iron Ore for Pelletizing (Balling) Iron ore must go through a lengthy preprocessing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate lowgrade ores This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron Casting is the process of pouring the iron into a mold thus giving it a shape Molds and pouring methods divide this process up Molds can be made as expendable molds (sand) or nonexpendable molds (metal) Pouring can happen via gravity, lowpressure or vacuum Controlling the pouring process becomes more important the more intricate the mold is Solidifying Cast Iron After the iron is cast Manufacturing Process of Cast Iron Castings  How Large Iron Chains Are Manufactured In The Factory?
