Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal.

What are the benefits of hot rolling?

Hot rolling can greatly reduce energy consumption and costs. The metal plastic deformation is high during hot rolling, and the deformation resistance is low, which reduces the energy consumption of metal deformation. Hot rolling can improve the processing performance of metals and alloys.

What is hot rolled steel process?

Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F. When steel is heated past its recrystallization point, it becomes more malleable and can be properly formed and shaped

Advantages of Rolling Process:

By rolling, uniform dimensions of the components can be obtained. It uses the same tool in the sense, the same rollers are responsible for the production of various components. Close tolerance is possible for the components in the rolling. high-speed production takes place in the rolling.

What are the disadvantages of rolling?

The disadvantages of Rolling process are as follows.

• The cost of equipment is high.

• It is suitable for large scale production only.

• Poor surface finish and thereby we need to secondary operations like finishing etc.
