Reversing cold mills

Cold rolling
Flexible production, high capacity, top versatility

Are you ready for an annual production of 100,000 to 500,000 tons? Then our single-stand reversing mill (RCM) is ideal for you because it offers you a very broad product spectrum. It's the best solution for rolling silicon steels and special steel grades. What makes the mill so efficient is that you can set the number of passes and the rolling speeds to suit your program. Also included in our range is our twin-stand Compact Cold Mill (CCM®) for capacities of up to 900,000 tpy, depending on your product mix. Furthermore, if you want to upgrade an existing RCM into a CCM®, our flexible extension package makes this possible - and affordable.

Design for a production of up to 500,000 tons per year

Single-stand reversing cold mill (RCM)

The RCM is the all-rounder among cold rolling mills. Mainly used for rolling low carbon steels, it's also a great solution for advanced grades such as silicon steels. And, if you want to produce small to medium batch sizes, this mill type is a highly efficient option. Depending on your product mix and the installed rolling technology, the capacity ranges from approx. 100,000 to 500,000 tpy.

Twin-stand Compact Cold Mill (CCM®)

Our successful Compact Cold Mill (CCM®), a two-stand reversing type, represents the very best in SMS group design. Featuring a capacity of 500,000 to 900,000 tpy, the CCM® closes the gap between the single-stand RCM and the multistand tandem cold mill. We engineer these mills to achieve the best investment and lowest operating costs for their capacity range.

Design for efficient production of high-strength and stainless steels

CVC® plus 18-HS mill

Some ten years ago, we developed our 18-HS mill design, which is available in combination with CVC® plus. This solution is ideal for rolling high-strength and stainless steels. It can be applied in reversing mills (RCM) as well as tandem mills (TCM).

X-Roll® Oil Bearing

Hydrodynamic roll-neck bearings from SMS group are highly advanced and elementary components of modern rolling mill technology. That's because they support the load-bearing backup rolls. Even under extremely tough operating conditions, they ensure long roll service life and minimal maintenance outlay. This is how roll-neck bearings contribute substantially to meeting the high requirements for optimal final strip geometry.

Coating technologies for rolling mills

Chrome plating of work rolls for longer service life

Chrome plating of work rolls

Chrome is one of the hardest metals, with excellent corrosion resistance and a low frictional coefficient. This combination turns the surface of work rolls to high-value and wear-resistant. SMS provides automated coating and carefully inspects the roll before and after chrome plating.

SMS uses EDT prior to chrome plating

Deformation behavior and appearance of the varnish depend on the structure of the strip surface. EDT (electric discharge texturing) is a machining process which removes particles from a work roll surface by energy of electric discharges. The electro-erosion leads to a higher number of peaks on the roll material's surface. This results in a roughness higher by 2-3 points compared to shot-blast-texturing (SBT). In combination with a 0.005 to 0.015 mm thick chrome layer, EDT is a successful solution for automotive sheets.
