Metallurgic Processes | Boundless Chemistry

The HIsarna steelmaking process is a process of primary steelmaking in which iron ore is processed almost directly into steel. The process is based on a new type of blast furnace called a Cyclone Converter Furnace, which makes it possible to skip the process of manufacturing pig iron pellets, a necessary step in the basic oxygen steelmaking ...

Circored and Circofer processes of ironmaking - IspatGuru

The Circored process operates at low reducing temperatures and uses natural gas to produce reducing gas by means of reforming. The process uses ore fines which have a particle size in the range of 0.03 mm to 1 mm and produces HBI. The iron ore fines are first dried and pre-heated in a fluid bed preheater system at around 850 deg C to 900 deg C.

Iron Ore Sinter - an overview | ScienceDirect Topics

The process basically consists of two reactors: a reduction shaft and a melter/gasifier reactor. Lump iron ore, sinter, and/or pellets are reduced by first being metallized in a reduction shaft by off-gases coming from the melter/gasifier reactor. The product consists of approximately 90% reduced iron.

DRI production | International Iron Metallics Association

Direct reduction processes for iron. Illustrations of the principal processes are shown below. The Midrex® and Energiron gas-based processes use predominantly iron ore pellets as feedstock, but sometimes with inclusion of lump ore in the furnace charge. The SLRN coal-based process uses lump ore and, increasingly, pellets as feedstock.

Iron processing - Ores | Britannica

First, moistened concentrates are fed to a rotating drum or an inclined disc, the tumbling action of which produces soft, spherical agglomerates. These “green” balls are then dried and hardened by firing in air to a temperature in the range of 1,250° to 1,340° C (2,300° to 2,440° F). Finally, they are slowly cooled.
