8/31/2020· Sometimes known as direct-reduced iron, sponge iron is a product that is produced using iron ore.The iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source. This type of iron can be produced in several different types of furnaces, including coke or charcoal ovens, blast ...

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 ...

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.

C., the Greek soldiers used iron weapons which had been hardened by quenching the hot metal in cold water. The Romans learned to reheat the iron after quenching in a process called tempering which made the iron less brittle.

3/16/2013· Fig 2 Principle of direct reduction process. Gas based process. In the gas based reduction processes, a vertical shaft kiln is used in which iron ore is fed into the top of the kiln and finished sponge iron is drawn off from the bottom after cooling it so as to prevent its re-oxidation.
Get PriceThe process of sponge iron making aims to remove the oxygen from iron ore. The quality of sponge iron is primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio of metallic iron to the total iron present in the product. Sponge iron manufacture is highly sensitive to raw material characteristics.
