@joemchang Ore is the rock which is mined from the ground.In certain areas the rocks will contain higher percentages of Iron Oxide,this is the "Ore" the more iron oxide in the rock the better.Sometime the ore is refined by crushing it and concentrating the iron oxide by removing waste rock,This refined ore is made into marble size pellets which are then put into the blast furnace with limestone,the limestone is used as a flux,it melts and removes unwanted impurities in the iron.
-
Why has no one considered combining the Blast furnace with the Basic Oxygen Furnace process so as to produce steel directly from the blast furnace? All that is required is the same water cooled oxygen lance as used in the BOS which is lowered into the molten steel after the slag has been tapped,to blow high purity oxygen through the iron to remove the excess carbon.This would remove the need for additional multi million $/£ plant and would reduce transport of molten iron/steel around the plant.

God is a construct of inferior human minds looking for meaning in the world.
No religion has any more reason to be true than any other, and they all have scientific inaccuracies in their ancient religious "teachings".

Well actually according to people like you everything and everyone is going to hell. So now Hell is filling up at an exponential rate which will cause it to be full before we finish reading your comment. Now since you educated us on this steel and ore stuff that will be in hell also. If hell continues to fill at this rate there will be noway for anything to burn at such a fast rate since it fills faster than it can burn. So Hell will freeze over. So we can repent but where will everyone go now??
