3 High Rolling Mill
Rolling mill consisting of three rolls or known as 3 High rolling mill is typically used for performing multiple reduction passes by wrapping material around the center mill roll and performing another reduction on the opposite mill roll pair. 3 High mill can also be used with varying mill roll sizes to induce a specific percentage of reduction of material on a single side of the work piece. This can be beneficial for cladded materials or for conditioning a single side of strip.
3 High Rolling Mill Equipment Options
With any Element Rolling mills, we offer several options that are available to increase the productivity of your equipment. Some of the options that we offer to maximize the capacity of our mills include:
- Quick roll change out options
- Repetitive reduction schedules
- Automatic gauge control features
Element mills offer a wide range of feed back options for roll positioning that provide tight output tolerances. Our most accurate design incorporates non contact positive roll detection that can provide output to tolerances of better than +/-0.0001″ (+/- 4um).
Rolling mill can have multiple different configurations that are used depending on material type, thickness and yield strengths. Element has built a wide variety of rolling mills to fit multiple applications.
3 High Rolling Mill Experience
Element has supplied 3 high rolling mills for specialty applications like clad material reductions or conditioning expanded metal sheet. The unique characteristics offered by a non even roll configuration have been used to induce specialized roll crowning for certain considerations, allowing a machine to function as a standard 2 high in most situations.
