Iron Ore Sintering Process in Steel Manufacturing

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 furnace. Sinter feed composition control is important because the various sinter feed ...

Sinter Plant Operations: Hazardous Emissions | SpringerLink

The CaO and MgO slag components do not coexist with iron ores and are added separately; therefore, CaO (such as limestone) and MgO (such as serpentine or dolomite) are mixed with iron ore fines as the sinter raw mix for the sintering process. The ultrafine iron ore reacts with the fluxes and forms a bonding matrix (silicoferrite of calcium and ...

Raw materials Sinter plant | ArcelorMittal

The sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an opengrained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.

How to Achieve Uniform Sinter Quality Analyzing Metals

According to the Environmental Protection Agency, the sintering process converts finesized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. It outlines the process as follows:
