2. Rotary Kiln Process of Making Sponge Iron HISTORICAL BACKGROUND The production of steel began in ancient times; but because of the complexity and slow speed of the ancient process, they could not be carried out on a very large scale.

MUMBAI: Tata Sponge Iron, a listed unit of Tata Steel, won a major reprieve Wednesday after shareholders voted in a second round of balloting in favour of a key proposal to allow related party transactions (RPTs) with group entities. Minority shareholders of Tata Sponge Iron had voted against the first resolution at the July annual general meeting.

Consists of silicon carbide bonded with silicon nitride, formed during a nitriding process. Key properties of this material are high operating temperature and strength, excellent wear and thermal shock resistance. Uses centre around high temperature applications such as refractories.

Rotary kiln The hot gases may be generated in an external furnace or by a flame inside the kiln. Our cement rotary kiln and sponge iron rotary kiln has been developed for performing drying, calcination and sintering work in a continuous process.

The results obtained show that an increase in the sponge iron proportion leads to an increase in the consumptions of electric power, graphite electrodes, furnace refractories, lime and deoxidizers.

Alternative iron source produced by heating an iron ore (generally having 65 to 70 percent iron) at a temperature high enough to burn off its carbon and oxygen content (a process called reduction) but below iron's melting point(1535°C or 2795°F).

The iron occur in Femineral ores contains impurities of Phosphorus, sulphur and high alkali as well as impregnations of waste rock. To produce a metallurgy treatable concentrate the ore has to be grind for mineral liberation, enriched for concentration and dewatered for transportation.
