Which metals are used for joining the railway track?

Question

Answer

Modern track typically uses hot-rolled steel with a profile of an asymmetrical rounded I-beam. Unlike some other uses of iron and steel, railway rails are subject to very high stresses and have to be made of very high-quality steel alloy.

Answer

Alloy of iron and aluminum

Answer

Iron & aluminum

Answer

Pure iron and aluminium

Answer

Iron and aluminium

Answer

The reaction between feric oxide and alluminium and the reaction used to make railway track

Answer

The reaction of iron (lll) oxide (Fe2O3) , with aluminium to produce iron is used to join railway tracks or cracked machine parts. This process is called thermite welding .
Fe2O3 + 2Al-------> 2Fe + Al2O3

This reaction of metal oxide to form metal y using aluminium powder as a reducing agent is know as thermite reaction.

Alumunium Oxide and Iron

Answer

Iron with aluminum.  By using thremit reaction

Answer

Iron and aluminium

Answer

Iron and aluminium .

Answer

Molten iron obtained as a product of the alumino thermine reaction is utilised to join railway tracks since once it cools down, it hardens and fill the gap between railway tracks.

Answer

Aluminum
but nowadays
iron is more preferable

Answer

The metals used for joining railway tracks are:

1. Cast Iron:
- Cast iron is a commonly used metal for joining railway tracks.
- It is known for its high strength and durability, making it suitable for heavy-duty applications like railway tracks.
- Cast iron rail joints provide a solid and stable connection between two track sections.

2. Manganese Steel:
- Manganese steel is another metal used for joining railway tracks.
- It is a high-strength steel alloy that exhibits excellent wear resistance and toughness.
- Manganese steel rail joints are able to withstand heavy loads and frequent train traffic without deformation or failure.

3. Carbon Steel:
- Carbon steel is widely used for various applications, including joining railway tracks.
- It is a strong and durable material that provides good structural integrity to the rail joints.
- Carbon steel rail joints are cost-effective and can withstand the stresses and strains experienced by railway tracks.

4. Alloy Steel:
- Alloy steel is a type of steel that is alloyed with other elements to enhance its properties.
- It is often used for joining railway tracks due to its high strength, toughness, and resistance to wear and tear.
- Alloy steel rail joints can withstand heavy loads and provide a reliable connection between track sections.

5. Stainless Steel:
- Stainless steel is a corrosion-resistant alloy that finds applications in various industries, including railways.
- It is used for joining railway tracks in environments where corrosion is a concern, such as coastal areas or regions with high humidity.
- Stainless steel rail joints offer excellent durability and resistance to corrosion, ensuring a long-lasting connection between track sections.

Summary:

In summary, the metals commonly used for joining railway tracks include cast iron, manganese steel, carbon steel, alloy steel, and stainless steel. These metals possess the necessary strength, durability, and resistance to wear and tear to withstand the heavy loads and frequent train traffic experienced by railway tracks. The choice of metal depends on factors such as cost, structural requirements, and environmental conditions. The rail joints made from these metals provide a solid and stable connection between track sections, ensuring safe and efficient railway operations.

Answer

Iron and Aluminium

Answer

Iron

Answer

Iron is used for the manufacturing of the rail lines because :-

{1} iron is a very strong metal as it can bear heavy load of trains
{2} as reactions are available to as to correct the default in it
{3} as iron can be reserved for long time along with the zinc cotting hence it preferred
