Iron and Steel Industry Historically, iron and steel have been the backbone of industrialization. Throughout the 1990s world steel production remained flat: at the lowest, 720 million metric tons in 1992, and at the highest, 789 million tons in 1999.

Study of the induration phenomena in single pellet to ...

The process for pelletizing iron ore fines is an important operation unit for producing high quality of raw materials for the subsequent reduction processes such as blast furnace or direct reduction. The process essentially involves production of green pellets and induration on a traveling grate furnace to promote inner partial melt and agglomeration that confers adequate physical and metallurgical properties.
