treatment of iron ore into pig iron
Single-Step Ironmaking from Ore to Improve Energy ...
2005-10-1 · During the heat treatment, dried greenballs are first transformed into direct reduced iron (DRI), then to transition direct reduced iron (TDRI) and finally to pig iron nuggets. The furnace temperature and/or residence time and the corresponding levels of carburization, reduction and metallization dictate these transformations.

Pig Iron Production – Interstahl
2022-2-7 · Pig iron usually consists of about 92 percent iron, three to four percent carbon, and varying amounts of silicon (0.5 to 3%), manganese (0.5 to 6%), phosphorous (0.1 to 2%) and traces of sulfur (0.01 to 0.05 percent). Grey pig-iron is produced when the pig-iron is cooled slowly and the carbon settles out as graphite on the raw material.
