Abstract:
Direct reduction of iron (DRI) is a constantly developing direction towards the reduction of energy consumption at production of iron. Application of the iron-carbon composites is the promising option aimed at wider use of coals and/or biofuels for ironmaking.Most of the coal-based DRI processes operate int a temperature range favourable for the formation of liquid FeO-rich slag inside of the iron-carbon composite. Interaction of this slag with the rest of a gangue as well as with the newly formed iron sponge determines efficiency of the reduction processes as well as further saturation of iron with carbon and sulphur. In the current research the interaction phenomena on the slag-metal interface for the slags representing liquid FeO-SiO2-CaO-Al2O3 system were studied. A comparison of slag interaction with Armco-Fe and with DRI material was done.
