29-07-2012· The use of iron-and-carbon-bearing brex with a basicity of 1.4 in a small blast furnace at a rate of 1444 kg/ton pig iron (80 % of the charge) has made it possible to completely eliminate the use of limestone and dolomite and reduce coke consumption by 150 kg/ton pig iron.
Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained by smelting iron ore in a blast furnace.Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.
use of limestone and dolomite in iron ore pellet production. Iron steel – British Lime Association (BLA) part of the Mineral . The principal uses of lime and dolomitic lime in this industry are as follows: Most of the world's iron is made in blast furnaces, which produce liquid iron.
Slags of the required basicity are obtained in blast furnaces at the Lipetsk Metallurgical Plant by adding raw fluxes (limestone and dolomite) to the charge in amounts of 200–300 kg/ton pig iron. Decomposition of the carbonates of calcium and magnesium in these fluxes requires a considerable amount of heat and increases coke consumption in the smelting operation by 45–65 kg/ton pig. To ...
limestone is used to remove impurities in the furnace and the main impurity of the blast furnace is silica (sand and rock) which is silicon dioxide. silicon dioxide is a solid at furnace temperatures so it reacts with calcium oxide from the decomp...
08-05-2013· 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 …
ported to iron and steel producing centers by lake boats and rail. Fluxstone is moved by barge where feasible. Fluxstone is also obtained in Ohio, Pennsylvania, and Illinois (Lankford, Jr., et al., 1985, Lawrence, JF., 1975). Until recently, major iron and steel producers owned limestone and dolomite quarries, but most have
Ooh, I like this one. Pig iron is iron made using pigs. Not just pigs, of course, it still requires iron ore and carbon and limestone and whatever else iron is made out of, but with the addition of pigs. The procedure for making it isn't much diff...
08-05-2013· Both limestone and dolomite are extensively used in an iron and steel plant in various processes. Specification of limestone and dolomite for iron making is less rigid. But for steelmaking limestone need to have very low SiO2 and Al2O3 since these elements require additional flux to neutralize them which increases the slag volumes.
Limestone and Dolomite and their Use in Iron and Steel Plant ... In ironmaking, limestone and dolomite are used in the production of sinter, ... which removes impurities from the iron ore while making liquid pig iron. Our limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products.
Iron ore pellets are spheres of typically 6–16 mm 0.24–0.63 in to be used as raw material for blast furnaces.They typically contain 64–72 Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder..
