CASE Group success story includes commissioning DRI Tunnel Kiln, first of its kind in India for use of all kind of iron ore fines. The cost-effective tunnel kiln technology brings final product which has density of 4 GMS/CC thus making it usable directly for melting in induction furnace, arc furnaces.
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...

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, Physical Specification – Size - 5-20 mm Oversize - < 5 % max
2 Materials Used to make Steel 2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe)

Tunnel Kiln - Manufacturers Suppliers in India. Sponge Iron, also known as Direct Reduced Iron is the product produced out of using iron ore. The iron ore is processed through reduction process by the use of gas that emits from natural coal gas resource.
Sponge iron production by tunnel kiln method was developed from 1911 as Höganäs method in Sweden. After many modifications, now this process is a sufficient and effective method for sponge iron production. The main advantage of tunnel kiln process is the possibility to build small plants with low investment costs which are feasible economically.
