Sponge iron production by tunnel kiln method was developed from 1911 as Höganäs method in Sweden. After many modifications, now this process is a sufficient and effective method for sponge iron production. The main advantage of tunnel kiln process is the possibility to build small plants with low investment costs which are feasible economically.
