Details1. The Bessemer Process. The Bessemer steel making process consists of blowing air through molten pig iron contained in a special furnace known as a converter which shaped like a huge concrete mixer (Fig. 4.2).The converter is made of steel plates lined inside with a refractory material. The type of refractory lining used depends upon the character of …
DetailsSchematic flow chart of the reduction-smelting process of iron ore using non-coking or charcoal as reductants. Therefore, the availability of DRI using non-coking coal as a reducing agent is determined by the availability of iron ore with over 65% Fe quality and the availability of a cheap source of non-coking coal.
DetailsThe Midrex® and Energiron gas-based processes use predominantly iron ore pellets as feedstock, but sometimes with inclusion of lump ore in the furnace charge. The Circored and Finmet / Finored gas-based processes utilize iron ore fines as feedstock.The SLRN coal-based rotary kiln process uses lump ore and, increasingly, pellets as feedstock.
DetailsIron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.
