Resumo
In this paper, the behavior of reduction and separation of iron and slag in carbon composite iron ore pellets has been investigated experimentally at the high temperature electric resistance furnace. Based on which, the mechanisms of iron nugget forming and the conditions of producing iron nugget at low temperature are discussed. Results show that the reduction of iron ore, carburization of reduced iron and the composition and quantity of slag are very important for producing iron nugget. Through optimization of process parameters, iron nugget can formed at 1,250°C. This study can provide theoretical and technical basis on iron nugget production.
