Iron Pretreatment Research

DURING the Symposium which was held at the National Metallurgical Laboratory two yearsago, my colleague
Mr. J. L. Harrison of British Oxygen Gases Limited described the conditioning of iron using oxygen
prior to the open hearth furnace in his paper
"Oxygen in Pyrometallurgical Techniques" The merits
of this process of iron pretreatment which he
described then have been widely discussed before
and since, and I do not think it is necessary to
dwell on the advantages which can be derived or on
the practice which has been established at various
works throughout the world.
