Abstract
Low alloy steel having an ultra low carbon content is produced using the basic oxygen process wherein an inert gas is introduced into the melt when the melt has a carbon content below about 0.06 weight percent, the oxygen flowrate is adjusted to from 10 to 40 percent of the inert gas flow rate and the oxygen lance height is reduced to from 30 to 60 percent of the normal lance height.
