Minerals & Metallurgy

Hot rolling is a metalworking process in which the metal is heated above the recrystallization temperature to deform it plastically during the machining or rolling operation.
This process is used to create shapes with the desired geometry and material properties, while maintaining the same volume of metal. The iron is passed between two rolls to flatten, elongate, reduce the cross-sectional area and obtain a uniform thickness. Hot rolled steel is the most common product of the hot rolling process and is widely used in the metal industry as a raw material for final products or subsequent processes.

Advantages of Hot Rolled Steel

Inexpensive

Hot rolled steel is usually cheaper because it is usually produced in larger quantities, which allows steel mills to reduce production costs.

 

Uniform Distribution of Magazines

Hot rolling results in a uniform distribution of impurities, such as slag, throughout the metal. Otherwise, they are concentrated in one location within the metal and can make it weaker in that location.

 

Low Pressure Requirements

Hot rolled steel is easier to work with Due to the higher temperatures at which the metal is rolled, the metal tends to deform. This reduces the pressure requirements.
As a result, it can be bent, cut and shaped into various shapes without additional heat treatment.

 

More Malleable

Hot rolled steel is more malleable, making it ideal for applications that require welding or other joining methods.

 

Better Dimensional Tolerances

Hot rolled steel has better dimensional tolerances, which means it is less likely to distort or twist during the manufacturing process.

 

Improved Mechanical Properties

Hot rolling destroys the casting organization of the ingot, refines the steel grain, eliminates tissue defects, makes the steel dense and improves mechanical properties. This improvement is mainly in the rolling direction, so that the steel is no longer isotropic to a certain extent; bubbles, cracks and looseness formed during casting can also be welded at high temperatures and pressures.

Hot rolling results in improved mechanical properties such as toughness, impact resistance, ductility and elongation.
