Since the fifties of the last century, single-stand 20-high mills have been part of SMS group’s product range. They have been and are continuously developed further. Today, SMS group ranges among the leading manufacturers of 20-high mills. Many of the first installations are still operating, which gives proof of the excellent quality and robustness of this mill design. Depending on the application, 20-high mills come in different sizes and in two versions: the closed, robust MonoBlock or the more flexible SplitBlock type. They can fulfill any material and surface requirement. Apart from the main application stainless steel, they can also be used for the production of silicon steel, copper and copper alloys as well as for titanium strips.
Concepts




20-high mill in MonoBlock design
Best in its class for extremely hard material gradesCompact and robust, this stand comes with superb rigidity. That makes it ideal for rolling even the hardest material grades, e.g. AISI 200 and 300 stainless steel. You can expect reductions of up to 90 percent. Furthermore, precisely coordinated mechatronic systems with highly developed actuators, together with control systems for thickness and flatness and via filter systems, ensure efficient production and outstanding strip quality.




20-high mill in SplitBlock design
Proven effective for challenging final productsSplitBlock stands from SMS group are capable of rolling a large product mix of material grades and thicknesses. Split into an upper and a lower half, the stand opens wider to accommodate larger-diameter work rolls. This design provides easy access during roll changing. It also simplifies the threading procedure.
Technology
You face constantly increasing demands on product quality and production efficiency. That’s why we equip our 20-high mills with a package of high-end rolling technologies so you can rely on smooth production and high yields. Included in these solutions are roll-gap actuators, thickness and flatness control, and advanced support systems.
