SPONGE IRON PRODUCTION FROM ORE -COAL COMPOSITE

In the year 1908 use of tunnel kiln started for iron oxide reduction. This process was invented by E.Sieurin as Hoganas process [3]. In 1954, more kilns came in operation in SWEDEN and USA. Presently it is more popular in China for sponge iron production from beneficiated iron ore fines cakes. In this process, the material passes through

Iron Ore Pellets and Pelletization Process –

Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is ...
