Rolling Mills | Metal Rolling Mill Machine

FENN engineers and manufactures a complete line of precision rolling mill machines, offering a wide range of standard and custom rolling mills for a variety of applications. These rolling mill applications include heavy ingot breakdown, laboratory research, coil-to-coil rolling, and precision strips.

Our rolling mills are available in 2Hi and 4Hi roll configurations. Mills may be either work roll-driven, back-up roll-driven, or a combination of both.

4HI mills with work rolls are offered as small as .500″ (12.7mm) in diameter
2HI mills are offered with rolls up to 16″ (400mm) in diameter

Designed and built to your production requirements

FENN Rolling Mills are engineered to meet the critical requirements of metallurgical research and applications up to 3.3 million pounds (1500 MT) separating force. FENN designs and builds rolling mills that are available with a complete offering of material handling options, processing, gauging, and labor-saving accessories. FENN offers customizable rolling mills for processing ferrous, non-ferrous, alloy, exotic, and engineered metals for production and laboratory applications.

FENN offers hot and cold milling machinery and combination mills that can accommodate both hot and cold rolling applications. Hot rolling is a process in which metal heats above the recrystallization temperature, allowing the material to deform on a microscopic level and take its new shape. Cold rolling is when the process is conducted at room temperature and does not require heating the metal.

Mill Types

A full range of mill types for the production of precision strips in straight lengths or coil-to-coil rolling.

Two-High

Three-High

Four-High

Combination

Tandem

Horizontal

Laboratory

Mill with Winders

Two-High
Generally, a 2-HI mill is used for hot or cold breakdown and finishing of bar, sheet or strip. A wide range of sizes with separating force capacities from 10,000 lbs. (4.53 MT) to over 3,000,000 lbs. (1360 MT) are available.
Three-High
A 3-HI mill is an economic milling solution for the breakdown of rod and ingot.
Four-High
A 4-HI mill may be used for finishing rolling thin gauge stock. 6-HI roll inserts are also available for narrow-width ribbon and foil products.
Combination
A combination rolling mill is a versatile “two-in-one” type of metal rolling mill that permits both 2-HI and 4-HI rolling operations.
Tandem
Tandem rolling mills combine two or more mill stands for multiple-pass rolling. They are often used with turbine heads, edgers, dancers, inter-stand tensiometers, payoff, and take-up equipment.
Horizontal
This type of rolling mill is designed for the field of powered metallurgy, plastics, and battery industries.
Laboratory
FENN designs custom, specialized mills engineered to meet the critical requirements of metallurgists and scientists in research and university fields and pilot line development.
Mill with Winders
A mill set up with winders on either side allows for the rolling of continuous coil for sheet or thin foil.

Accessories
All FENN rolling mills, including laboratory models, offer a complete offering of material handling, processing, gauging, and labor-saving accessories.

Laboratory Mills

From our Engineers to your Research Facility
For research and development (R&D) applications, FENN manufactures laboratory rolling mills equipped with Statistical Process Controls (SPC) to track and record “real-time” data. R&D projects may require the testing of multiple materials. Laboratory rolling mills are designed to accommodate a variety of materials for testing and manipulation. The precision strip mills FENN engineers are designed to meet the critical requirements of metallurgical research. With separating force capabilities from 30,000 pounds. (13.6 MT) to 1,175,000 pounds (533 MT), our mills have received wide acceptance in laboratories, where precision, flexibility, and compactness are important. Our trusted engineers are prepared to work with research facilities, colleges, and universities to provide a customized mill suited to their unique requirements.
