Jul 07 2017 Application of limestone and lime in iron and steel plant During the production of iron by blast furnace (BF) route limestone is added either in the process of sintering or as a direct feed in the blast furnace Limestone is normally added during ironmaking for obtaining either neutral or Get Price The raw materials used to produce pig iron in a blast furnace are iron ore coke sinter and limestone Iron ores are mainly iron oxides and include magnetite hematite limonite and many other rocks The iron content of these ores ranges from 70% down to 20% or less

Creating Iron

At this point the liquid iron typically flows through a channel and into a bed of sand Once it cools this metal is known as pig iron To create a ton of pig iron you start with 2 tons (1 8 metric tons) of ore 1 ton of coke (0 9 metric tons) and a half ton (0 45 metric tons) of limestone The fire consumes 5 tons (4 5 metric tons) of air

advantages of lizenithne in sponge iron process The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron

Introduction to Iron and Steel Steel: Iron with a bit of carbon in itβ€” generally less than 1% 4 Introduction to Iron and Steel A few definitions and general descriptions are in order Pig iron: Raw iron the immediate product of smelting iron ore with coke and limestone in a blast furnace

Our chemical grade limestone is used in the ironmaking process to produce the slag 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 Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory

Pig iron is an intermediate product of the iron industry also known as crude iron 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 The traditional shape of the molds

advantages of limestone in sponge iron process Limestone Quarry Plant Stone Crushing Machine Our mobile limestone crushering plant can eliminate the obstacles of the crushing places and circumstances and offer the high efficient and low cost project plants for the clientIt has many advantages for limestone quarrying processAnd it is widely used in process the materials such as quartz limestone

The raw materials used to produce pig iron in a blast furnace are iron ore coke sinter and limestone Iron ores are mainly iron oxides and include magnetite hematite limonite and many other rocks The process of extracting iron from ore produces great quantities of poisonous and corrosive gases the future of iron production

I Pig iron is made in a blast furnace by smelting iron ore with coke and limestone A In general it has around 95 percent FE content plus certain impurities such as carbon (say 4 percent) and silicon manganese phosphorous and sulfur

The limestone and ore form a slag that floats on the surface Impurities including carbon are oxidized and float out of the iron into the slag When the carbon content is right you have carbon steel Advertisement Another way to create steel from pig iron is the Bessemer process which involves the oxidation of the impurities in the pig

The manufacture of iron is based on the principle of reduction of iron oxide with carbon monoxide This reduction process is carried out in a furnace called 'blast furnace' Iron manufacturing process pig iron cast iron and wrought iron - Genuine chemistry - The ultimate resource for Chemistry

HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called hot metal The blast furnace is a huge steel stack lined with refractory brick where iron ore coke and limestone are dumped into the top and preheated air is blown into the bottom

CHEMICAL GRADE LIMESTONE

Our chemical grade limestone is used in the ironmaking process to produce the slag 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 Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory

Blast furnace slag is a combination of silica and other non-ferrous components of iron ore ash from coke used as a reducing material and limestone auxiliary material Because its specific gravity is less than that of pig iron during the heating process the molten slag rises above the pig iron allowing it to be easily separated and recovered

Our milled limestone is used in the ironmaking process to produce the slag which removes impurities from the iron ore while making liquid pig iron Our milled limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory

This process is used to make iron The limestone forms a substance called slag with the rock of the iron ore The bottom part of the furnace is called the hearth When it has filled with liquid pig iron and slag the slag is removed This is called skimming Slag is lighter than iron and does not mix with iron It floats on top of the iron
