Abstract
The contents of carbon range in this case from 0.3 - 1.0%; in order to obtain phosphor contents below 0.015% 1/6th to 1/2 pref. 1/3 of the lime requirements are added in the form of a mixture of lime/oxide of iron containing 10 - 55% and pref. 30 - 45% iron in the form of oxides of iron and this during the period extending prior to blowing to half the injection period. The oxide of iron may be entirely or partially replaced by an equivalent quantity of manganese oxide and or oxides favouring the solution of lime and/or combinations of elements of the first and third principal groups of the periodic system, added individually or in combination in order to lower the melting point of CaO.
