摘要

Application: iron and steel industry, steel production in converters. SUMMARY OF THE INVENTION: iron is poured, a seat metalized pellets having a degree of metallization of not lower than 90%, purged with oxygen, a seat lime. Purging lead to the intensity of 3,3-5,0 m / m-min. lime is produced additive t two portions, the first in an amount of 75-85% of the total flow is fed in the range of 10 ... 40%, and the second ,, in an amount of 15 ... 25% of the total flow in the range of 70 ... 85 % blowing time duration, respectively. Table 1. ate with
