Forging and rolling are two of the most common metal processing techniques used in the manufacturing industry. Both methods involve applying pressure to the metal to create the desired shape, but each has its own advantages and disadvantages.
In this article we explore the differences between forging and rolling, including the types of each technique, their respective advantages and disadvantages, and the impact on the mechanical properties of the final product.
We also delve into the various types of forging and rolling, such as longitudinal, transverse, and inclined rolling, as well as free forging, die forging, and flashless die forging.
Whether you are a seasoned industry professional or simply curious about the manufacturing process, this article provides a comprehensive overview of forging and rolling, including the factors that determine which method is best for a specific application.
So whether you want to improve the quality of your steel products, optimize your manufacturing process, or simply expand your industry knowledge, read on to discover the differences between forging and rolling and how they can impact your bottom line.
Rolling
What are you up to?
Pressure processing method in which a blank piece of metal is passed through the space between a pair of rotating rollers of various shapes, causing the cross-section of the material to decrease and its length to increase as a result of compression of the rollers. This method is the most commonly used steel production technique and is mainly used to produce profiles, plates and tubes.
(2) In terms of the degree of transformation, the deformation degree of forging is much greater than that of rolling, which means that forging is more effective than rolling in breaking eutectic carbide.
(3) In terms of processing cost, forging is much more expensive than rolling.
For key parts, parts subject to high loads or impacts, and parts with complex shapes or strict requirements, forging must be used.
(4) Forgings have complete metal flow lines.
Mechanical work after rolling destroys the integrity of the metal flow lines, significantly reducing the life of the part.
The image below shows the metal flow lines of casting, machining and forging parts.
