Our working Areas are Sponge Iron Plant , Power Plant , SMS and CCM .
The major Raw Materials required for production of Sponge Iron by the rotary kiln process are: sized graded Iron Ore and Non-Coking coal. Limestone, in small quantities, is also required to scavenge the sulphur.
The quality requirement of Sized ore for sponge iron production can be classified into:-
1) Physical requirements:-
Strength and granulometry are the two important physical requirements. The ore should be hard, and posses high strength. The optimum tumbler strength of the ore should be 90 percent minimum. Depending on the reducibility, closely calibrated ores in the size range of 5 to 20 mm generally used.
2) Metallurgical requirements:-
The ore should be highly reducible, thermally stable and have a low tendency for sticking and disintegration during heating and reduction.
3) Chemical requirements:–
Apart from the removal of oxygen, no other major chemical change takes place in direct reduction. The gangue material in sponge iron, originating from Iron Ore, namely, silica and alumina and the sulphur and phosphorous contents adversely affect the economics in subsequent steel making operation. Therefore, the ore should be high in iron content and low in gangue.
An increasing number of Industrial consumers are considering the option of setting up their own Captive Power Plant.
In most of the cases co-generation of Power will not only reduces the environmental pollution but also reduce strain on the company’s economy.
The present scenario therefore not only favors, but also warrants adoption of co-generation system in Plants to make them more economical and to ensure clear environment.
Sustainability of a Power scheme in decided by viability of technology, adaptability for integration into the existing infrastructure economic competence and environmental acceptance, co-generation of Power utilizing the Waste heat is an attractive proportion for Plants, thereby reducing green house emission.
In turn co-generation assumes greater significance in the Indian content in view of the Power shortages in many states, which results in production losses and high-energy consumption apart from increased dust losses due to unstable operations.
The industry can mitigate the problem of Power shortage and poor quality of Power to a considerable extent by adopting co-generation system based on Kiln Waster heat.
