Study of the reactions between iron ore slag and refractories

For the fabrication of iron ore pellets at LKAB (LuossavaaraKiirunavaara AB), one of the methods used is to sinter the pellets in a rotary kiln. This Kiln has a drift temperature of 1250°C in average. During this process a coating, causing the wear of the refractories materials, is formed, inducing expensive maintenance periods.

Conversion of Sponge Iron From Low Grade Iron ore And .

The Iron ore is charged from one end with noncoking coal which is in the lump form or pellets and heated from the other end, thus carrying counter current movement of raw materials and gases. The reduced ore comes out as product from opposite end. During reduction the rotary movement of the kiln requires good strength of raw materials.

Direct Reduced Iron | Industrial Efficiency Technology ...

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.
