Smelting in cupola furnace for recarburization of direct reduction iron (DRI)

A Comprehensive Static Model of an Iron Bath Smelting Reduction Process with Thick Slag for Alumina-Rich Iron Ore

Alumina-rich iron ore is a widely existed polymetallic deposit in the nature, and it has a high comprehensive utilization value. Because the alumina and iron contents of alumina-rich iron ore vary from each other, there are many different measures and processes to recover iron and alumina from the various kinds of alumina-rich iron ore. In the blast furnace (BF) ironmaking process, the alumina ...

A System for Recycling Rock Mineral Wool Process Residues Back through a Cupola Melting Furnace

The production process for rock mineral wool insulation products generates a number of residue streams with different physical characteristics. Together these add up to a significant proportion of the raw materials input to the process. Previously, recycling of the residue had not been viable because of the abrasive nature of the different materials streams and specific processing constraints a...

Interaction Mechanism between Refractory and Melts in Iron Bath Smelting Reduction Process

The corrosion behavior of three sorts of refractories based on alumina-graphite were studied by immersion tests. The melts included smelting reduction molten slag and corresponding carbon saturated molten iron. The influence of test temperature, FeO content in slag and specimen rotative velocity on the corrosion rate of refractories was examined. By means of SEM and EDS, the microstructure chan...
