Iranian Customers Order Sponge Iron Rotary Kiln Equipment
Sponge iron, also known as direct reduction iron, uses high-quality ore and uses the principle of redox reaction. Direct reduction method has been developed for hundreds of years, but it was not until 1960s that great breakthrough was made. In the 1990s, its production technology is becoming more and more mature and has made great progress. The following is the actual situation of Iranian customers visiting our company to order sponge iron rotary kiln:
At present, more than 90% of the world's direct reduced iron is produced by gas-based process.
Direct reduction method is divided into gas-based method and coal-based method. In the former, H2 and co gases are produced by cracking natural gas as reducing agent to reduce iron oxide in iron ore to sponge iron in shaft furnace, tank furnace or fluidized bed. There are mainly Midrex method, hyliii method, fior method and so on. The latter uses coal as reducing agent to reduce iron oxide in iron ore in rotary kiln equipment, mainly including fasmet method.
