High productivity in stainless steel manufacturing with 18-HS mills
HS stands for "Horizontal Stabilization" – in this 18-roll stand, the very thin rolls are supported against lateral buckling. SMS group has developed the 18-HS mill design so that high-strength and stainless steel grades can be produced efficiently. Specifically, in a five-stand tandem cold mill (TCM) in 18-HS design, reductions of up to 70 percent are possible. Even a second run of hard material is no problem. Integrated in a TCM, our 18-HS allows you to set up a full, continuous production route for stainless steel. By using rolling oil, this type of plant produces surface finishes that match cold rolled strip produced in 20-high mills. The 18-HS design is also available in combination with CVC® plus, a technology package for strip profile, contour and flatness control.
Concepts
18-HS mill design in continuous production routes
Setting up a continuous rolling mill for stainless steel strip is a costeffective option, especially if you aim for an annual capacity of more than 400,000 tons. Compared with using individual reversing mills for large production volumes, a tandem mill means lower investment and operating costs.

First in line here is the continuous entry section. It includes these machines: double pay-off reel, crop shear for the strip head end, welder, strip accumulator, and strip cleaning section. Downstream of that, the tandem mill consists of up to five stands in 18-HS design plus a powerful pinch roll unit on the exit side. Also designed for continuous operation, the runout section features a double tension reel.




CVC® plus 18-HS mill
Efficient production of high-strength and stainless steelsIt has been some ten years since SMS group developed the 18-HS mill available in combination with CVC® plus. This design is not only ideal for rolling high strength and stainless steels, but also fully operational in both both reversing mills and tandem mills.




Reversing cold mill (RCM) in 18-HS design
Flexible stainless steel productionKey components of 18-HS roll sets for RCMs are slim laterally supported work rolls. They come in diameters of between 120 and 160 millimeters, depending on the mill stand size. What they have in common is that they are all capable of high reductions. With this mill type even AISI 200, 300 and 400-grade unpickled material can be rolled into high-quality finished strip.
