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.


Production Process and technology for direct production of Sponge Iron from Iron Ore fines withough any need of either pelletisation nor sintering is offered adopted Tunnel kiln and Hematite Iron ore fines. Shape of produced sponge …


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.

Output of the production process, which does not meet quality requirements. Applicability This methodology applies to project activities that utilise waste heat released from furnace(s)/kiln(s) in a sponge iron manufacturing facility to pre-heat raw material(s) before feeding it into the furnace(s)/kiln(s).


Sponge iron kiln's cylinder: The design of the sponge iron rotary kiln cylinder is more reasonable. The cylinder is rolled with a Q235-B steel plate to ensure five mechanical properties, usually with automatic welding. The wall thickness of the cylinder is generally 25 mm, and that of …


In the year 1908 use of tunnel kiln started for iron oxide reduction. This process was invented by Sieurin as Hoganas process . In 1954, more kilns came into operation in Sweden and USA. Presently it is more popular in China for sponge iron production from beneficiated cake of …

The coal base DRI rotary kiln process for production of DRI / Sponge Iron has its many parameters to increase the quality as well as productivity which need careful operations throughout the process. Number of DRI processes came up and rotary kiln process with solid coal as fuel found to be most acceptable process in the world.


Tunnel Kiln history dates back to 1807 when Hoganas first used this process to produce iron powder of 99.9% purity. When iron ore is mined or processed (in a crusher), lots of fines are generated. Quantity of fines generation is a function of …


Sponge iron powder . The Höganäs process is a direct reduction method for production of sponge iron powder using magnetite ore (Fe3O4) and carbon as raw materials. The reduction process takes place in a gas fired tunnel kiln at around 1200°C for 60 hours producing a sponge iron cake that is crushed, milled and

German Kiln Technology

The roller hearth kiln, initially developed for table ware, is used now for more elaborate and diverse products. Compared to tunnel kiln, roller hearth kilns do not need the thermal indifferent kiln cars or the heavy lining and the large rail network. The resulting advantage is a considerably shorter firing cycle.


Sponge iron is also referred to as direct reduced iron, metalized iron, or hot briquetted iron. Sponge iron is used in the iron and steel industry as a substitute for scrap in induction and electrical arc furnaces. Over the years, the shortage of …
