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 176 C in a continuous belt-fed furnace...

Such iron ore cannot be directly charged in a blast furnace In the early 20th century, sinter technology was developed for converting ore fines into lumpy material chargeable in blast furnac Sinter technology took 30 years to gain acceptance in the iron making domain, but now plays an important role in the blast furnace route of iron making...

pellets, and sinter in blast furnaces with subsequent refining of molten iron and scrap in oxygen-blown process The electric furnace is used to make steel, stainless steels, ferroalloys, and special alloys, whereas ferromanganese is often made in blast fur- nac Fluxes are used in all of these processes, and either limestone...
