sinter making history for blast furnace

Sinter plant - Wikipedia

Many countries, including India, France and Germany, have underground deposits of iron ore in dust form (blue dust). Such iron ore cannot be directly charged in a blast furnace. In the early 20th century, sintertechnology was developed for converting ore fines into lumpy material chargeable in blast furnaces. Sinter technology took 30 years to gain acceptance in the iron-making domain, but now plays an important role. Initially developed to generate steel, it is now a means of using metallurgical waste gene

Jan 31, 2021  The sintering process is utilised to convert weakly-bonded iron ore granules into a partially fused porous sinter cake using coke breeze as fuel, and then into final product – iron ore sinter with specific properties. In a typical sinter strand, air is drawn down and a flame front is allowed to propagate at 1200~1400℃ through the granule bed.
