Limestone and Dolomite and their Use in Iron and Steel
2013-5-8 Limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. Basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material. The process of iron making is the reduction of iron ore to produce iron.
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
Difference Between Sponge Iron and Pig Iron Compare
2011-4-30 The key difference between sponge iron and pig iron is that we can produce sponge iron by direct reduction of iron ore through reducing agents whereas the production of pig iron is by melting iron ore with charcoal and limestone at very high pressures.. Sponge iron and pig iron are different forms of iron that we can produce from iron
Can We Use Hematite In Sponge Iron Making
2020-10-1 sponge iron machine. Plant Details MGM Group Iron Ore: Iron ore is the source of iron and available in oxide form namely hematite (Fe2O3). As only oxygen can be removed from the iron ore during the process of making sponge iron iron,ores rich in iron content of 65percent and above is preferred. Hematite from Iron Ore, Lumps.

In addition to blast furnace (BF) process in iron and steel production Corex, Romelt, Midrex, Hyl-3 processes are used currently. Pig iron or sponge iron with scrap iron addition are loaded into electric arc furnaces (EAF) for steelmaking [1-4]. There is a problem of comparative assessment of carbon dioxide through emission (carbon
11.17 Lime Manufacturing US EPA
2015-9-10 11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate. When the rock contains

Iron and Steel Manufacturing IFC
In the BOF process, coke making and iron making precede steel making; these steps are not necessary with an EAF. Pig iron is manufactured from sintered, pelletized, or lump iron ores us-ing coke and limestone in a blast furnace. It is then fed to a BOF in molten form along with scrap metal, fluxes, alloys, and high-purity oxygen to manufacture
Calcium Carbonate an overview ScienceDirect Topics
They occur in the form of limestone and chalk, formed from fossils, and marble, formed from the metamorphosis of sedimentary rock. They consist mostly (>98%) of calcium carbonate (CaCO 3), with trace amounts of magnesium carbonate, iron oxide, and aluminum silicates. Dolomite is a blend of calcium and magnesium formed by metamorphosis.
