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 ...
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).

To make pig iron, iron is extracted from iron ore.This 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.
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.

When the mixture of are, coke and limestone descends through the top of the furnace, a blast of air comes across it is the upward direction. The mixture gets heated up and reactions take place in ...
Nov 03, 2019· Pig iron is a metal material that results when iron ore, charcoal from coal, and limestone are melted together under intense air pressure.When the combined material cools, it forms a high-carbon product known as pig iron.The cooled material is rarely used by itself, as the large amount of carbon makes the material brittle and unstable.
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
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, .
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.

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.
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 so-called basic oxygen steelmaking, the carbon is oxidized by blowing oxygen onto the liquid pig iron to form crude steel.
Nov 14, 2017· 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...
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.
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 so-called integrated plants, which start from the extraction of iron ore .
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.
The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being disposed of and the molten iron being poured into molds were it solidifies, now being in the form of pig iron. The pig iron is loaded into to an ...
