What is Cold Roll Forming?
Hot rolling is a metalworking process that involves heating metal above its recrystallization temperature to deform it plastically during the working or rolling operation.
Cold rolling passes metal through rollers at temperatures lower than its recrystallization temperatures. The metal is compressed and squeezed, which increases its yield strength and hardness.
Steel shape rolling is a laborious process that necessitates great heat and force. The metal is reheated to around 1200°C before being continuously fed through rollers to draw the desired dimensions.
Roll bending involves pushing an extrusion around three different rolls in a triangular shape. The rolls are adjusted to form a precise angle, ranging from 0 to 360 degrees, and can roll horizontally or vertically.
Flat rolling is the most basic type, with a rectangular cross-section of the starting and ending material. The material is fed between two rollers known as working rolls, which rotate in opposite directions. The gap between the two rolls is less than the starting material's thickness, causing it to deform.
Controlled rolling improves steel properties to levels comparable to those of more highly alloyed or heat-treated steels. Controlled processing conditions refine the austenite structure and produce fine ferrite grains.
Advantages and Disadvantages of Cold Roll Forming
Advantages of Cold Roll Forming
Cold rolling has many unique advantages and can frequently be preferable to other options. Firstly, due to the lack of high temperatures during the process, you get a better surface quality for various applications.
Another benefit is that cold-rolled steel has tighter tolerances. Simply put, it has a higher tolerance level, e.g. it is thinner without losing any of its strength which is unique to this process.
With the cold rolled forming process, you get multiple options, including; full hard, half hard, quarter hard, and skin rolling. However, it is worth noting that only full cold rolled processes can offer you up to a 50% reduction in thickness to give the tightest tolerances.
Disadvantages of Cold Roll Forming
While there are many advantages of cold roll forming, there are some disadvantages too. As there is no heat during cold rolling, the steel isn't as malleable as when heat is used, making it harder to shape.
It can also be more expensive than heat rolling which can be costly to businesses; however, the advantages often make up for this by giving a more robust product with a better surface finish.
