Runshi has been creating and manufacturing tough, durable metal-forming machines for almost a century. Rolling Mills are one of Runshi's most popular product lines. Runshi provides a variety of standard and custom-sized rolling mills for a number of applications, such as heavy ingot breakdown, laboratory research, coil-to-coil rolling, and precise stripping.
A rolling mill, in its most basic form, is a machine that lowers the thickness of a metal without surrendering any of the material; that is, material is always shifted and never lost. Rolling mills, by definition, do not create scrap. The rolling process has a metallurgical effect on the materials, and the necessary material thickness may be attained while simultaneously creating the desired tensile strength. An embossed mill is a rolling mill that has been constructed with specialty tooling to imprint designs on the material. Furthermore, grooved mills may be used to minimize round and bar stock by lowering the total area of the material while keeping the form.
There are several types of rolling mills available for various rolling applications:
Straight lengths or coil-to-coil breakdown rolling
Finish rolling of narrow gauge metal with high tolerances—often a 4-HI mill or cluster mill
Powder metallurgy rolling on a horizontal mill for the plastics and battery industries
Dissimilar metal bonding
Camber adjustment of BI-metal strips following electron-beam welding
Grooved rod rolling rollers in square or circular parts
Pattern rolling may be done using embossed rollers.
Laboratory rolling mills can be used for R&D purposes.
Although the number of rollers used varies, rolling mills always employ at least two. The material is gripped and pushed forward by a series of revolving rollers. The material is then forced through a narrower aperture than its beginning thickness. The rolls themselves lower the thickness of the material, resulting in a finished thickness that is smaller than the initial thickness. In terms of lowering the area of the material without material or scrap loss, the rolls perform similarly to a draw die or swager die.
The flexibility of the roll gap, on the other hand, enables the operator to run multiple thickness reductions with a single piece of equipment. As a result, a rolling mill is the most commonly used machine for adjusting the thickness of varied strips. Using an integrated HMI station, the operator can manage the process and make modifications throughout production.
As previously stated, there are several types of rolling mills. Rolling mills, on the other hand, process various metals via one or more sets of rollers to reduce thickness, generate uniform thickness, stamp a pattern, or condense loose material. Rolling mills from Runshi may be individually designed and manufactured to assist metal producers in conducting test runs to enhance their processes for optimal productivity and efficiency.
