Efficient Configuration for the Vent System of a 250-Ton Steel-Pouring Ladle

Resumo

This article describes the main principles behind a method developed at the Institute of Ferrous Metallurgy of the Ukrainian Academy of Sciences (IChM NANU) to validate an efficient configuration that was found for the vent system of a 250-ton steel-pouring ladle in the BOF shop at the Dneprovskiy Metallurgical Combine (DMKD). Statistical analysis of production data over a three-year period of use of ladles with such an injection system showed that the campaign of the linings had increased by amounts ranging from 10.7 to 18.8%.
