Thermal analysis of sponge iron preheating using waste energy
Melting of iron by EAF is a very energy consuming process in which temperature of sponge iron particles is raised from ambient temperature up to 1500 °C. Since electrical energy which is the most expensive form of energy used in EAF, lowering the energy consumption is a major concern in these industries. Various technologies Swedish steel producer SSAB, mining company LKAB and power company Vattenfall have produced hydrogen-reduced sponge iron at a pilot scale as part of their collaboration on the HYBRIT [Hydrogen Breakthrough Ironmaking Technology] initiative, which they call a world first. A conversion of LKAB’s operations will require a SSAB, LKAB and Vattenfall produce hydrogen-reduced sponge iron Mining

Pre-Feasibility Report
Presently, most of the coal based sponge iron plants in India, use iron ore lumps. The requirement is generally 1.6 to 1.8 t/ t of sponge iron. These high requirements are mainly due to the fines generated in handling the purchased ore from the sources to the plant. This reduces the kiln campaign length and increases the loss of ore fines.Of these 266 districts, 135 districts have two or more assets dependent on coal a coal mine, thermal power plant, sponge iron plant, steel plant etc. It was, however, said that if the bricks sector was excluded (which is mostly informal and the numbers fluctuate year on year), the number of people dependent on coal would still be around 2.5India’s coal transition likely to be a “messy and complicated exercise”

Air Quality Impact of Sponge Iron Industries in Central India
The sponge iron has of late come up as a major input material for steel making in India. As per the National Steel Policy issued by the Ministry of Steel India will produce 110 million ton of steel by 2020 which will require 30 million ton of metallic sponge iron compared to 13.9 million ton produced in 2006 (Battacharjee 2007).Under the Since last few years, sponge iron has emerged as an alternate raw material for steel making. The Indian Government has recognized sponge iron as a vital sector for growth of Indian steel industries. At present, India is largest producer of sponge iron with a largest number of coal based sponge iron plant of total capacity around 12.8 million ton.Energy survey of the coal based sponge iron industry

HYBRIT partners choose Gällivare for fossil-free sponge iron
The HYBRIT pilot plant will be able to make fossil-free sponge iron to make fossil-free steel for prototypes to customers already in 2021. The partners claim the initiative has the potential to reduce carbon dioxide emissions by 10% in Sweden and 7% in Finland, as well as contribute to cutting steel industry emissions in Europe and globally.Sieurin invents sponge iron method The Höganäs Method is invented by engineer Emil Sieurin. The method means reducing iron ore with the help of coke, lime and clay. After patenting the method, Höganäs starts production in 1911 and in 1912 a plant is built. Later on, Höganäs will start grinding the reduced iron to powder, sponge iron powder.A leader in metal powders born in Sweden Höganäs

Phosphorus in water not only degrades water quality but also leads to a waste of resources. In this study, adsorption thermodynamics and kinetics were used to study the effect of sponge iron on phosphorus removal, and a filtration bed was used to simulate the phosphorus removal in polluted water. The results showed that the Waste gas from the rotary kiln of the sponge iron plant exits at a temperature around 900° C. This gas has a lot of sensible heat and can be used for energy integration.

Design Modifications for Energy Conservation of Sponge Iron Plants
During the operation in the coal based sponge iron plant, a tremendous amount of heat is generated and significant part of this heat, associated with the waste gas, remains unutilized. It appears worth interesting to modify the process that facilitates the integration of heat available with the waste gas.
