Blast furnace?

  1. May 27, 2007 #1
    might be a naive question, but concerning the blast furnace:

    they blow pure o2 through the raw iron to oxidise impurities like carbon etc, but that would mean that exactly the right amount of o2 would have to be blown through before the iron also started reacting, which in turn means the impurity conc. must be explicitly known? and how might this be done?

    just out of interest...

    thanks :)
