The sintering converts fine-sized raw material, iron ore, coke breeze, limestone, mill scale, and flue dust into an agglomerated product (sinter) at suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a cohesive matrix and then placed on a travelling grate called the sinter strand. A burner

Sintering: A Step Between Mining Iron Ore and Steelmaking. 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). It's a major ingredient in steel.

Sinter is the primary feed material for making iron in a blast furnace. During the iron ore sintering process in iron and steel manufacturing, 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 belt-fed furnace. The production of high-quality sinter is …

Fundamental pore formation mechanisms in iron ore sinter and pellets were investigated. The study was first conducted with tablets made from iron ore and limestone particles, with and without addition of coke, and the results were then tested and proved in real pellets made with a laboratory ball mill and in real sinter made with a sintering pot.

Puddling is a step in the manufacture of high-grade iron in a crucible or furnace. It was invented in Great Britain during the Industrial Revolution.The molten pig iron was stirred in a reverberatory furnace, in an oxidizing environment, resulting in wrought iron.It was one of the most important processes of making the first appreciable volumes of valuable and useful bar iron (malleable ...
