Limestone is also a very important industrial mineral. Its chemical properties make it a valuable mineral for a wide range of industrial/manufacturing uses. Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight. The limestone which is used by iron and steel industry in bulk quantity is a bedded type sedimentary limestone. The two most important constituents are calcite and dolomite. Limestone frequently contains magnesium carbonate, either as dolomite CaCO3.Mg CO3 or magnesite (MgCO3) mixed with calcite. The EU28 total lime demand in 2017 was estimated at about 20 million tons, out of which about 40% are consumed in the iron and steel industry. Steel remains the major Limestone is used mainly in the iron making part of steel production where it is added to the iron ore before entering the blast furnace. The limestone reacts with acidic impurities called slag Iron ore fluxed sinter is the main ferrous burden of Jindal south west steel limited (JSWSL) blast furnaces. In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore and to provide an appropriate slag composition of the blast furnace. 1999-9-1 5. Conclusions. From the six different mixtures of limestone, blast-furnace slag, and converter slag, samples M 3, M 5, and M 6 showed relatively good mechanical properties. It was concluded that, in these compositions, the LSF was higher and the alite phase, C 3 S, developed better. Sample M 6 needs more attention because there is no converter slag, the iron content is low, and SR and AR are 2015-9-10 12.5 Iron And Steel Production 12.5.1 Process Description1-3 The sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a 2021-3-20 Mild steel. Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things nails, wire, car bodies, ship building, girders and bridges amongst others. High carbon Pure iron is too soft and reactive to be of much real use, so most of the "iron" we tend to use for everyday purposes is actually in the form of iron alloys: iron mixed with other elements (especially carbon) to make stronger, more resilient forms of the metal including steel. Broadly speaking, steel is an alloy of iron
