After half a century of exploration, it developed into a direct reduced iron tunnel kiln called the Hoganas method. The Hoganas process is divided into two steps: first, the iron ore is directly reduced by carbon in the tunnel kiln to obtain the DRI block, then the DRI block is crushed and sorted, and finally, the direct reduced iron is obtained.

was the Höganäs tunnel furnace process for fine ore reduction with carbon [3]. In the beginning of the 1930ies the Krupp-Renn process was developed, which reduce iron ores with carbon as reductant in a rotary kiln [4]. In the year 1932 the gas-based reduction of lumpy iron ores was realized in the Wiberg process in Söderfors, Sweden [5].
