Due to Iran prospect of producing 55 million tons steel until 2020 direct reduction processes have been developed in Iran and sponge iron is a very good charge for steelmaking furnaces instead of iron scrap.
Possibility of using both magnetite and hematite ores using different grades of coal and natural gas as the process main fuel are advantages of sponge iron production in tunnel kiln.
Researches and experimental operations in Aramico Company result in construction of sponge iron production pilot plant In this plant Tabas iron ore and coal was used to sponge iron production by tunnel kiln method Engineering design and construction of sponge iron production line by tunnel kiln method is operated by Aramico technical and engineering group.
Sponge iron is an ideal charge in steelmaking industries and it is used for making different grades of steels like stainless steels tool steel bearing steel springs steel and other alloy steels Using sponge iron instead of iron scrap in steelmaking furnaces has many advantages include.
Although iron powder could be produced in sponge iron tunnel kiln production line and it is the main raw material for powder metallurgy production lines.
In sponge iron production plant by tunnel kiln method after crushing and screening raw materials iron ore coal and limestone are mixed and charged in storage bins in certain ratios By using an automatic charging system raw materials mix is charged in SiC crucibles These crucibles are transported by wagons to the tunnel kiln and after preheating reduction and cooling sponge iron is produced The product is crushed and could be produced as iron powder or sponge iron cold briquettes.
Material handling and storage equipment magnetic separators screens tunnel kiln burners wagons SiC crucibles charging and dis charging systems crushing and milling machines briquetting machine and iron powder reduction furnace are the main machineries of sponge iron production plant by tunnel kiln method.
Boudouard reaction dolomite DRI Iron ore metallization non coking coal pellets reduction Rotary kiln Sponge iron Sulphur Coal based Direct Reduction Rotary Kiln Process The coal based direct reduction rotary kiln process was developed for converting iron ore directly into metallic iron without the melting of the materials.
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 the quality of ore i e whether it is hard or soft.
