Jun 11, 2019· The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including
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 belt-fed furnace.
Sintering is a widely used method to agglomerate iron-containing fine-grained materials. In sintering the ore fines, concentrates, fluxes, and coke breeze are thoroughly weighed, moistened, and mixed. The sinter mix is fed on the grate of the sintering machine to make a 0.3–1 m high bed. The grate is an endless strand of slowly moving pallets.
Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (limestone) fines. In addition to base mix, coke fines, flux fines, sinter fines, iron dust (collected from plant de-dusting system & ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often called mixing and nodulizing drum.
