medium carbon ferrochrome of around 2 c respectively therefore de carburization is a necessary refining step in the current industrial setting in the case of steelmaking from blast furnace hot metal there are two necessary and sequential refining steps 1 de carburization and removal of dissolved nitrogen and silicon in liquid iron in the basic oxygen furnace bof then 2 final control of temperature and composition of liquid steel in a ladle furnace lf before casting there are two slags produced in traditional flow sheets one in the bf for the removal of gangue in ore and ash in coal and coke and the other in a converter for the de carburization and removal of impurities in hot metal such as si mn s and p the present invention may be exemplified by the experimental results reported below composite pellets also referred to as u201c green pellets u201d made of typical iron ore and medium or high volatile coal with a c o ratio where c stands for total carbon in carbonaceous reductants and o stands for combined oxygen in reducible oxides in ore both in atomic grams in the range of 0 95 to 1 05 may be reduced to dri of 95 metallization in a laboratory under psh furnace operating conditions subsequently the melting of the resultant dri under a controlled atmosphere without any flux.
