Sintering: A Step Between Mining Iron Ore and Steelmaking
Sintering: A Step Between Mining Iron Ore and Steelmaking By Alison Cestari 06112019 The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe) It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3) The sintering technology was originally developed for the purpose of utilizing in the blast furnace the iron ore fines and the iron present in the metallurgical waste of a steel plant But currently the focus has changed Now the sintering process aims to The Sintering Process of Iron Ore Fines – IspatGuru Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability Ore Sintering an overview ScienceDirect Topics
Sintering Technology for Iron ores and Optimization of
The sintering technology is basically an agglomeration process for the iron ore fines which is dependent on heat to melt the surface of the smaller particles together to form larger agglomerates A typical sinter plant consists of a number of sequential operating units with the sinter machine at the heart of the plant Iron ore sintering is a type of powder metallurgy used to pretreat iron before using it in manufacturing applications Sintering involves heating iron powder to partially, but not completely, melt the iron particles The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heatWhat Is Iron Ore Sintering? (with pictures)Sinter is the primary feed material for making iron in a blast furnace Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous beltfed furnaceSintering Process Equipment Used in Iron and Steel
