Abstract

The first blast furnace at Monlevade Works, based on charcoal, started up in 1937. Since then the route blast furnace-oxygen steelmaking has been used. In the course of the time, Monlevade Works ironmaking area went past some changes until reaching the present situation: one sinter plant and one blast furnace based on coke. This blast furnace started up in December 1999 and its nominal capacity is 1,040,000 thm/ year. This paper aims at showing the evolution of blast furnace operational performance, within a seven year operation which allowed a production of 1,103,935 thm in 2006.
