What is the difference between pig iron and wrought iron Difference between pig iron and wrought iro

Iron is divided into pig iron and wrought iron, which means that the carbon content of wrought iron decreases after various heating, which increases the hardness. The difference between pig iron and wrought iron is how much carbon it contains. Pig iron has a higher carbon content and wrought iron has a lower carbon content. The carbon content of steel is between pig iron and wrought iron.

Steel has toughness and is mainly used for tensile force, while iron mainly contains more carbon than steel, and the toughness is not good, so it is generally used for pressure. Tempered glass refers to the addition of other trace elements to the glass during processing, so that it has the same properties as steel, hence the name. Tempered glass has the characteristics of high impact strength (4 5 times higher than ordinary flat glass), high bending strength (5 times higher than ordinary flat glass), good thermal stability, and smooth, transparent and cut.

In the event of super impact damage, the fragments are scattered and fine particles, without sharp edges and corners, so it is also called safety glass.

It has a hardness close to that of steel and has many uses. Its hardness makes it versatile and can be found everywhere.

According to the different carbon content, iron-carbon alloys are divided into two categories: steel and pig iron, and steel is an iron-carbon alloy with carbon content. Carbon steel is the most commonly used ordinary steel, which is easy to smelt, easy to process, inexpensive, and can meet the requirements of use in most cases, so the application is very common. According to the different carbon content, carbon steel is divided into low carbon steel, medium carbon steel and high carbon steel.

With the increase of carbon content, the hardness of carbon steel increases and the toughness decreases. Alloy steel, also known as special steel, adds one or more alloying elements on the basis of carbon steel to change the microstructure and properties of steel, so as to have some special properties, such as high hardness, high wear resistance, high toughness, corrosion resistance, and so on. An iron-carbon alloy with a carbon content of 2% is called pig iron.

Pig iron is hard and brittle, but it is pressure and wear-resistant.

Pig iron is the product of iron ore after primary refining, wrought iron is the product of iron ore after refining (refining again and adding or removing certain elements will give a variety of properties of steel), from the perspective of performance, pig iron because it contains more carbon and other impurities, brittleness is relatively large, other properties are unstable, wrought iron brittleness is smaller than pig iron, other properties are relatively stable.

Good afternoon<> dear

We're happy to answer for you! Pig iron refers to the iron obtained directly from iron ore after smelting, its composition is impure, contains a large number of impurities and carbon, has low hardness, high brittleness, and cannot be used to make steel and castings with high strength requirements. Wrought iron is an iron material made after smelting and refining, its composition is relatively pure, contains less impurities and carbon stove rent, the hardness is higher and the toughness is better, and it can be used to manufacture various iron materials with different strength and toughness requirements.

Therefore, pig iron is mainly used for smelting steel and casting, while wrought iron is widely used in the manufacture of building structures, mechanical parts, noisy tools, etc., and is one of the indispensable basic materials in industrial production.

Difference Between Pig Iron and Wrought Iron: Different Uses, Different Flexibility, Different Plasticity, Different Thermal Conductivity, Different Rust Situations.

1. Different uses.

Wrought iron is widely used for forging and welding, while pig iron is mainly used for steelmaking.

2. The flexibility is different.

As the name suggests, the flexibility of pig iron is relatively hard, whereas the flexibility of wrought iron is comparatively softer.

3. The plasticity is different.

Because of the good flexibility of wrought iron, it can be used to make a variety of utensils, pig iron is hard, and its plasticity is relatively poor.

4. Different thermal conductivity.

Wrought iron has good thermal conductivity and can be heated quickly; The thermal conductivity of wrought iron spine balance is relatively poor, and it takes a long time to heat.

5. The rust situation is not dug to do the same.

Pig iron is not prone to rust due to its inherent properties, whereas wrought iron is very susceptible to rust.
