Ironmaking process and ironmaking system
2011
An ironmaking process and an ironmaking system are provided in which ammonia, which is transported by an established method, is used as a reducing agent to thereby lower the temperature for the reduction reaction and make it possible to reduce the amount of the reducing agent to be used, fuel consumption, and carbon dioxide emission.
A feed material for ironmaking and ammonia are supplied to a reactor (3) and subjected to reduction reaction, thereby producing iron. The ammonia may be supplied to the reactor (3) after being preheated to at least the temperature at which the feed material for ironmaking is reduced. Oxygen or air may be supplied to the reactor (3).
