tunnel kiln and iron powder reduction

General situation of reducing iron powder industry

2019-12-25  Tunnel kiln is one of the oldest ironmaking methods. In the rest of the world, the tunnel kiln method is only used in one kind of reduction process of powder metallurgy reduction iron powder production. In addition to China, there is no report of using tunnel kiln to produce DRI for steelmaking.
