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.
Sponge Iron Tubes , which is used in induction furnaces, has various features, including:
- Flexibility in receiving input load (pellet soft, oxide shell, concentrate, etc.)
- Production of low carbon product for induction melting units
- 5% optimization of energy consumption and production slag during melting compared to other forms of sponge iron
- No need to bribe the product and the possibility of direct consumption in smelting
- Possibility of more storage and transportation and reduction of oxidation risks of the product compared to Midrex sponge iron
- Ability to produce products with a total iron content of 90 to 98% with metallization of 96% and above.
- Possibility of feed production of metallurgical powder production units
