This paper describes the development of Lhoist’s atmosphere-controlled Vario-Furnace and its modification to conduct comparative metallurgical studies of iron ore feedstocks for direct reduction and blast furnaces, paving the way toward a CO2 emission-free steel industry. This furnace is designed to perform qualitative research on reduction behaviors of (iron ore) feedstock up to 500 g sample size in mixed-gas atmospheres (CO, CO2, H2, N2, O2, CH4, SOx) at temperatures up to 1,000°C. The setup, the gas flow optimization and the adaptation for metallurgical tests (reducibility, swelling, reduction-disintegration) are described, as well as the metallurgical results obtained on two types of industrial pellets.
