Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state without melting as in the blast furnace The reducing agents are carbon monoxide and hydrogen coming from reformed natural gas syngas or coal Iron ore is used mostly in pellet and/or lumpy form
WhatsApp
— This process can be a difficult technique First off because searching for ore is challenging there is no assurance that you will smelt the desired metal The entire process of gathering and smelting iron ore could result in the production of impurities and slag Second forging newly extracted metal into any shape is a time consuming process

These systems range from an 80 Ton coreless tilting furnace used to cast giant bronze ship propellers to removable crucible furnaces used to melt a few kilograms of brass With their highly efficient power supplies and advanced engineering Inductotherm channel and coreless melting systems set the world standard for productivity and reliability
WhatsApp
— The process involves 5 steps resulting in recycled steel indistinguishable from virgin steel made from iron ore Recycling steel promotes green building by conserving the energy used in virgin steel production and minimizing greenhouse gas emissions and environmental degradation due to primary steel production
WhatsApp
— As scrap is available in abundance and cheaper in Syria the cost of liquid iron produced from IF route using scrap is much lesser when compared to MBF hot metal produced from iron ore coke and other raw materials In this way the advantage of cheaper scrap also is well utilized 2 Experimental
— Sinter is used as an iron feedstock within a blast furnace The sintering process consumes energy mainly in form of coke About MJ energy per kg of sinter is required A direct reduction plant is fed with iron ore pellets or lump ore The pelletizing process is outside the system boundaries for the energy related consideration of Fig 6
WhatsApp
— Contrary to the almost pure iron of meteoric origin manufactured iron pig iron or hot metal and steel are ferrous alloys of iron with carbon and further impurities Fig Carbon lowers the melting point of iron from 1538 °C in pure iron to 1147 °C in the eutectic with % C Carbon content in steel is up to % that corresponds to
WhatsApp
— Steelmaking based on direct reduced iron DRI and its compacted derivative hot briquetted iron HBI is an anticipated important global alternative to current steel production based on FeOx reduction in blast furnaces due to its lower specific CO2 emission The majority of DRI is melted and refined in the electric arc furnace with
WhatsApp
Along with sponge iron about 10 15% pig iron is added in induction furnace Pig iron is produced using iron ore A high carbon bath is required to take care of unreduced iron oxide present in the sponge iron Once the melting is over steel is taken to LRF station where it is refined in terms of sulphur and phosphorous
