Ironmaking Process - an overview ScienceDirect Topics

2012-4-4  The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13].Corresponding to each temperature interval, typical

FINEX® — ENVIRONMENTALLY SAFE IRONMAKING

In the Finex process, fine iron ore is directly charged at the top of a cascade of fluidized-bed reactors, where it is heated and reduced to direct-reduced iron (DRI) by means of a reduction gas derived from the gasification of the coal in the melter gasifier. The DRI fines are processed into hot-compacted iron, transferred in hot condition to ...

Blast furnace process - tec-science

2018-6-21  Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.The carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking plant.At sufficiently high temperatures, the carbon can
