Iron ore is reduced to its metallic form through smelting which is called pig iron. It has a low melting point ( 12000C) as compared to steel ( 1400+). Depending upon the kind of reduction its Carbon content may vary between 4% to 3% with matching Silicon and Manganese content to make it harder or less harder, white, mottled or gray. Typically its hardness varies between 250 to 450 BHN( a measure of hardness), Tensile strength between 50 to 25 ks and % Elongation around 0 and 0.5. It comes in three qualities : White, Mottled and gray pig iron, name rendered as per their color and appearance. Pig iron is not used for working upon but it is the raw material for manufacturing various types of gray iron and steel.
What else can I help you with?
What are the differences between pig iron and wrought iron in terms of their properties and uses?
Pig iron is brittle and contains high carbon content, making it unsuitable for shaping. Wrought iron is malleable and has low carbon content, making it ideal for forging into shapes. Pig iron is mainly used in steel production, while wrought iron is used for decorative purposes and in construction.
What is the key element that influences the properties of iron?
The key element that influences the properties of iron is carbon. The amount of carbon present in iron determines its strength, hardness, and ability to be shaped through heat treatment processes like quenching and tempering.
What are the properties of cast irons?
Mechanical Properties of Ductile Iron. Ductile iron is characterized by having all of its graphite occur in microscopic spheroidsCast iron is formed by remelting pig iron, and is useful for a variety of engineering purposes.Properties and Uses of Iron. Iron is one of the three magnetic elements (the others are cobalt and nickel). Cast iron is very brittle (it cracks easily
Is pig iron magnetic?
Yes, pig iron is magnetic due to its high iron content. The iron atoms in pig iron are arranged in a way that makes it magnetic, allowing it to be attracted to magnets.
How do you make pig iron?
Pig iron is crude iron as first obtained from a smelting furnace, in the form of oblong blocks.
What are three raw materials to make pig iron?
iron core , coke and limestone are needed to make pig iron
Which is purer wrought or pig iron?
Pig iron is generally an intermediate product of the wrought iron and steel making process. Pig iron is virtually useless due to the very high impurity content. "Pure" is a strange quantification of the comparison between pig iron and wrought iron. Pig iron is pure pig iron and wrought iron is pure wrought iron if there is a "standard" for the respective materials. I'm guessing that the answer you want is that wrought iron is "more pure."
What are the impuritys in pig iron?
The main impurities in pig are carbon (C) and Silicon (Si)
Why pig iron essential while melting of cast iron?
During the manufacture of Cast Iron, an intermediate product is Pig Iron. Further processing results in Cast Iron.
Pig iron is produced by heating the coke iron and limestone in a what?
Pig iron is produced when heating * Iron ORE (not iron as the question says!) * Coke * limestone in a Blast Furnace.
Does pig iron oink like a pig when it's bent?
No.
Where does pig iron comes from?
Where does Pig Iron come from? Pig iron is the intermediate product of smelting iron ore with coke, usually with limestone as a flux. Pig iron has a very high carbon content, typically 3.5-4.5%,[1] which makes it very brittle and not useful directly as a material except for limited applications.
