Sieurin invents sponge iron method The Höganäs Method is invented by engineer Emil Sieurin. The method means reducing iron ore with the help of coke, lime and clay. After patenting the method, Höganäs starts production in 1911 and in 1912 a plant is built. Later on, Höganäs will start grinding the reduced iron to powder, sponge iron powder.

TUNNEL KILN (Coal-based DRI Plant) Production of sponge iron by Tunnel Kiln technology was developed in 1911 as Höganäs method. Now very popular, the technology has become an effective method for sponge iron production. With the Tunnel Kiln technology, it is possible to build small plants with low investment costs.

About Sponge Iron/DRI: Sponge Iron, also known as Direct Reduced Iron is the product produced out of using iron ore.
