Sponge Iron | High & Low Carbon Grade Supplier &
High Carbon grade. High-carbon Sponge iron is an alternative to scrap in EAF, as it is chemically homogeneous, free of harmful or redundant elements, and requires less coke and secondary metallurgical operations. Due to the specific combination of DRI, it is possible to accurately predict the final analysis of steel in continuous feeding with sponge iron. In EAF-based processes, also usingBrief introduction of Sponge Iron - Iron&Steel,The grade and amount of iron in sponge iron is between 84% to 95%. This high grade of iron makes sponge iron a good source for steel production. As mentioned, It is obtained from recycling natural or processed iron ore that has not reached the melting temperature.Direct reduced iron - Wikipedia,Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting,Sponge Iron - an overview | ScienceDirect Topics,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,Extracting More Sponge Iron Is Imperative To Boost Steel,,29/09/2019· In this way, by promoting the establishment of a large number of small and medium scale DRI units, it would be possible to extract good amount of sponge iron from low-grade iron ore and non-coking coal as well as natural gas to boost the production of steel. At the same time, the sponge iron units can employ a good number of skilled and semi-skilled persons. In this regard, both the Central,SPONGE IRON INDUSTRY : CURRENT SCENARIO,low fixed carbon grade. Coal is used as a reducent for sponge iron making in the furnace. •The availability of scrap of required quantum is unlikely and therefore scraps needs to be replaced more and more by DRI. •Local supply of scrap is diminishing as generation of scrap in India due to improvement of technology is getting continuously minimized. •As per World Steel Dynamics (WSD,

Sponge iron, also called as Direct Reduced Iron, is the product created when iron ore is reduced to metallic iron, usually with some kind of carbon (charcoal, etc), at temperatures below the melting point of iron. This results in a spongy mass, sometimes called a bloom, consisting of a mix of incandescent wrought iron and slag.It is a substitute for scrap and is mainly used in making steel,SPONGE-IRON - Shakambhari Group,The charge is prepared according to the proposed chemistry for the targeted grade. Sponge Iron and other ingredients along with lime in a close requisite ratio is charged in the Arc Furnace. b) Melting : Melting is accomplished by injecting energy to the charge materials in the form of electrical energy through three graphite electrodes. Carbon injected inside the furnace reacts with oxygen,Conversion of Sponge Iron From Low Grade Iron ore And,Anand, Rounak Sneh and Kumar, Prakash and Paswan, Dayanand (2016) Conversion of Sponge Iron From Low Grade Iron ore And Mill Scale Through Simulating Tunnel Kiln Condition.

The present investigation deals with the feasibility study of the processSPONGE IRON PRODUCTION FROM ORE -COAL COMPOSITE,the low grade beneficiated iron ore cake are directly used for manufacturing of sponge iron in tunnel kilns. The material bed in Tunnel kiln being stationary, it does not require high strength and thermal stability of the raw material. This gives the opportunity for charging composite pellets or briquettes which could possibly enhance kiln productivity and efficiency. In order to explore the,about us - ORISSA SPONGE IRON AND STEEL LTD.,Orissa Sponge Iron & Steel Ltd. (OSIL) was promoted in the year 1979. It, Process developments had to be carried out in-house to use low grade coal available in India as reductant. This was essential to make the process economically viable. After painstaking R & D work a new technology was developed dispensing with the liquid fuel. The process having capability in using coal having ash over,PATNAIK STEELS and ALLOYS LTD.,The State of Orissa in India has abundant deposits of high-grade iron ore and low-grade non-coking coal. An opportunity therefore exists for building a steel plant for manufacturing billets using coal based sponge iron and electric power generated from WHRB as well as combustion of coal fines and coal char via the electric furnace and continuous casting route. The quality of steel produced is,
