Energy Audit Methodology of Sponge Iron Manufacturing

sponge iron manufacturing process or kiln operation with a view to finding out major energy sav-ing potential of the unit. In the research work we find that it is the incomplete reaction of coal that causes the major energy inefficiency in the process. Substantial amount of un-reacted carbon

sponge iron sludge manufacturing process

Sponge iron is a product of the direct regeneration of iron ore (pellets). In the immediate recovery operation, without the need for iron ore smelting, its oxygen is removed and its appearance becomes spherical sponge iron sludge, and the reason for naming it is

SPONGE IRON PLANT

MANUFACTURING PROCESS Coal based Direct reduction process is classified based on the reducing agent namely solid. Most solid reduction process use non-coking coal as reducing agent due to abundantly available non-coking coal. The process proposed to be adopted is the rotary kiln proposes using Non-coking coal and iron ore.

DESIGN OF WASTE HEAT RECOVERY SYSTEM IN A

in the sponge iron process. For this purpose a case study of typical sponge iron production process is considered. The waste gas from a sponge iron plant exits at a temperature of around 200-300 C. A lot of sensible heat is lost with these gases. This heat is utilized to preheat the air entering to kiln.

SPONGE IRON – Lloyd's Metals

Sponge iron making is a process in which iron ore lumps (typically 5mm-18mm size) are tumbled with a 'select' grade of iron-coking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled, magnetically separated, screened and size wise in finished

Sponge Iron

Sponge iron is the product created when iron ore is reduced to metallic iron, in the presence of coal, at temperatures below the melting point of iron. The external shape of the ore is retained with 30% reduction in weight due to oxide reduction resulting in change in

OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION

1. Krupp Sponge Iron Process The Krupp. Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and de-sulphurizing agents (lime-stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge

The Making of Iron Steel

The BOS process uses pure oxygen, injected by a lance, for refining the relatively impure hot metal (and scrap is used for temperature control). The electric arc furnace uses primarily electrical energy to supply heat to melt scrap steel, sponge iron, or mixtures of scrap and other iron units. Compared to the BOS process, the EAF requires

Sponge iron Manufacturing process

Sponge iron is a metal product that is produced by a direct reduction of iron ore in solid-state. Sponge iron is a good alternative to waste and is mainly used in the manufacture of steel via secondary routes. The process of making sponge iron occurs by
