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 ...

Pig iron alongside scrap iron, coke and limestone is liquefied in a vertical furnace called cupola. Here likewise the carbon and different impurities introduce oxidize in nearness of a little measure of air, to shape slag. The liquid iron got from dome heater can be thrown into forms. It is, thus, known as cast 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 ( metric tons) of ore, 1 ton of coke ( metric tons) and a half ton ( metric tons) of limestone. The fire consumes 5 tons ( metric tons) of air ...
Chemical Grade Limestone (CGL) requires demanding specifications for physical and chemical properties and consistency. Produced at 8 locations in the Northeast region, for ironmaking processes. Blast Furnace – CGL is utilized to produce the slag which removes impurities from the iron ore reduction process to make the liquid pig iron. Pellet Production – CGL is pulverized and utilized in ...
Dec 29, 2012· Pig iron is the intermediate product of smelting iron ore with a highcarbon fuel such as coke, usually with limestone as a flux. Charcoal and anthracite have also been used as fuel. Pig iron .

Creating Steel | HowStuffWorks The pig iron, limestone and iron ore go into an openhearth furnace It is heated to about 1,600 degrees F (871 degrees C) 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 .
Description. Pig iron is the intermediate product of smelting iron ore with a highcarbon fuel such as coke, usually with limestone as a flux. Charcoal and anthracite have also been used as fuel. Pig iron has a very high carbon content, typically –% which makes it very brittle and not useful directly as a material except for limited applications.
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.
May 08, 2013· Iron and steel making. Basically limestone is used as a slag former. 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. Iron ore normally contain gangue materials such as silica (SiO2), Alumina (Al2O3) along with sulphur (S) and Phosphorus (P).
This is done by adding calcium oxide, which reacts with the iron sulfide contained in the pig iron to form calcium sulfide (called lime desulfurization). In a further process step, the socalled basic oxygen steelmaking, the carbon is oxidized by blowing oxygen onto the liquid pig iron to form crude steel.
Production Process and Classification of Pig Iron – lifelarn. Oct 02, 2014 The basic materials used for the manufacture of pig iron are iron ore, coke, and limestone. The coke is burned as a fuel to heat the furnace; as it burns, the coke gives off carbon monoxide, which combines with the iron oxides in the ore, reducing them to metallic iron
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
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.
The phase transition of the iron into liquid in the furnace was an avoided phenomenon, as decarburizing the pig iron into steel was an extremely tedious process using medieval technology. Uses. Traditionally, pig iron was worked into wrought iron in finery forges, .
Production of Pig Iron by Using the Romelt Process . In the iron and steel industry in the world there are currently two types of factories that produce ferrous metals. There are socalled integrated plants, which start from the extraction of iron ore .

Nov 11, 2015· Iron ore, coke and coal is the main raw material for iron making process. Iron ore contains a certain amount of silica, the purpose of using limestone is to change silica and other impurities into ...
To make pig iron, iron is extracted from iron produces sintered ore and coke, and molten iron is taken out of the blast furnace. Even here, you''ll find Tsubaki products widely used in a variety of situations.
Posted in Manufacturing Process. ... Limestone A flux. In addition to iron, pig iron contains various other constituents in varying form of impurity such carbon, silicon, sulphur, manganese and phosphorus etc. It has the following approximate composition which is as given as under.
