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 reactions will take place.

Read More2013-7-2 The process is for the production of liquid iron (hot metal) using iron ore fines or any other appropriate ferrous feed material. The smelting is carried out in a molten iron bath using coal as the reductant and energy source material. The principal raw materials required for the process are iron ore fines, coal and fluxes (limestone and dolomite).

We regard ITmk3 as the 3rd generation iron-making process, whereas the current mainstream process of blast-furnace/converter is the 1st generation and the direct reduction process such as MIDREX is the 2nd generation. The process is
