What is a Rolling Mill Used For?

Rolling mills are used to roll hot or cold ferrous or non-ferrous metal strip, wire and even bar. Depending on the type of rolling mill, it can be used for hot or cold disintegration and finishing of bar, sheet or strip. They can also be used for finishing, embossing or compacting of thin gauge billets. Mills are designed to meet the unique needs of manufacturers, metallurgists and scientists in the materials research industry and are used in a variety of applications in a variety of industries. The advanced design, precision, versatility and uncompromising reliability of FENN mills make them the best choice for customers in the materials research, aerospace, military and automotive industries.

Typical application example:

• Strip or coil-to-coil split rolling

• Finish rolling of tight tolerance thin gauge billets - usually a 4-HI mill

• Powder metallurgy rolling with horizontal mills - designed for the plastics and battery industries

• Bonding of dissimilar metals

• Curvature correction of bimetallic strips after electron beam welding

• Grooved rolls for bar rolling - square or circular cross section

• Embossing rollers can be used for embossing

• Laboratory grinder for R&D Used Bar Mill- Juxinde

Metallurgical Research & Development:

Rolling mills are ideal metal forming equipment for metallurgical research and development because they are easily customizable for a variety of processes. Research facilities may use rolling mills to test various metallurgical properties and need to store all the information collected. Some of the software functions that FENN mills are equipped with include data acquisition, automatic roll pass programming, torque and breakaway force measurement. These features allow users to test, adjust, document and run smoothly without using multiple mills. Thanks to FENN's design of the combined mill, researchers can perform metallurgical tests using both hot and cold rolling methods on a single mill.

Examples of alloys that can be machined on FENN mills:

•       steel

•       copper

•        lead

•       Platinum

•       aluminum

•      Superconducting materials

•      Strange Metals

•      Precious metals

•      Ferrous non-ferrous metals and Engineering Materials

Industries Using Rolling Mills:

Not only do research universities use rolling mills for testing, they can also be used for laboratory testing by companies in the aerospace industry. Manufacturers of aerospace components may need to test new alloys to determine which alloys are suitable for aircraft construction. Rolling mill machinery is used to manufacture finished products for the aerospace industry, such as turbine blades for jet engines and the production of aircraft fuel cells.

In addition to metallurgy and alloy research for military applications, mill machinery can also be designed for the embossing of military materials, such as those used in grenades. The mill can also be designed to process titanium profiles for military aircraft frames.

Manufacturers in the automotive industry use rolling mill machinery for a variety of applications. Auto parts suppliers and producers rely on FENN mill machinery to precisely reduce material for a variety of auto parts, including but not limited to:

• collets

• Snap ring

• Bearing steel

A rolling mill is a metal forming machine that processes various metals through one or more sets of rolls to reduce thickness, create uniform thickness, stamp designs, or compact loose material. FENN mills can be custom designed and built to help metal fabricators conduct trial runs to improve their processes for maximum productivity and efficiency. Contact FENN to learn more about creating a custom mill for your metal forming application. FENN rolling mill machinery can be designed to be combined with other metal forming and forming equipment such as turks heads, edgers, dancers and payoffs to create application specific lines.

Types of Rolling Mills

The rolling mill compresses the metal to a uniform thickness, bends it into custom shapes, and creates custom-sized strips. There are many different types of rolling mills, and the best one for your product depends on the metal and rolling process your manufacturer will use.

Various markets require custom metal products to function. And because many industries require custom rolled metal, these products are extremely common in everyday life. You've almost certainly used something from a rolling mill at some point, even if you didn't realize it! From your car to your phone to your jewelry, mill-made products are used every day.

Rolling Mill Uses

Almost all metalwork is custom in some way. Because of this, there are many different types of mills - each serving a different purpose. For example, one mill may specialize in flat rolling, while another in grooved rolls. Larger mills will have higher rolling capacity, but not all jobs are large enough to require so much raw material.

Custom metalwork requires fine-tuned machines that can create products such as wire, strip, and strip from a variety of metals. The rolling operation and equipment used will depend on what material is required and what the end result is.

Main Types of Rolling Mills

Specifications for the different types of metals and end products will help determine which type of mill your product will be produced on. The following are the main types of rolling mills:

• Continuous rolling mill. The sheet metal passes through several rolling mill stands, each of which thins the metal.

• Cluster mills. A set of metal coils lined up for thinning.

o An example of a cluster mill is a 20-high cluster mill. These mills take rolling forces along the entire width of the mill through support bearings, which provide impressive precision tolerances. Some feature advanced technology, including automatic instrument control and dynamic power crown adjustment.

• Planetary mill. This type of rolling mill is mainly used for crushing or grinding metal stock rolls.

• Two-high, three-high and four-high mills. Depending on the number of rolling mill stands, these rolling mills roll in opposite directions to press and finish the metal.

In addition to different types of rolling mills, your metal fabricator may use cold or hot rolling mills to process certain types of metals and produce different products.


In addition to outputting a uniform metal sheet, strip, or wire, the rolling process actually strengthens the metal itself by treating the material at extremely hot or cold temperatures. There is hardly any runoff or material loss thanks to advances in mechanical engineering that increase the productivity of metal rolling mills.

Another characteristic of the rolling process is the rolling load of the rolling mill. Small machines can handle two coils at a time, and larger machines can handle three and four sheet metal coils. The product will be a durable, uniform product regardless of the rolling process used.


As the name suggests, a two-roll mill uses two rolls stacked on the mill stand. One roll goes through the machine clockwise and the other roll goes through the machine counterclockwise.

These cold rolling mills are good at processing soft metals such as copper and lead. And because they are smaller than three-roll and four-roll mills, two-roll models are generally less expensive than larger options. However, due to their size, they cannot always thin the metal like a three-roll mill can.
