High performance rolling for efficient production of advanced steel grades
The production of high quality strip in volumes of up to 2.5 million tons per year poses an enormous challenge. Perfect for such an operation are SMS group tandem cold mills - our powerful flagships in the cold rolling sector. You can operate them in either batch or continuous mode as CTCM (Continuous Tandem Cold Mill). Optionally, it's possible to arrange them as coupled pickling line/tandem cold mills (PL/TCM). The large number of plants we have built, especially for very wide strips, reflects the trust our customers worldwide place in our proven plant technology. We constantly improve our cold rolling technology, so you can also produce the latest material grades accurately and cost-effectively.
Concepts
Pickling line/tandem cold mill (PL/TCM)
Central to the PL/TCM is the direct coupling of pickling and rolling. This ensures a continuous production flow. The main units on the entry side are: a pay-off reel, laser welding machine, tension leveler, turbulence pickling line, and several horizontal strip accumulators. Next in line is the mill section consisting of several mill stands in CVC® plus design and a continuous exit section with drum shear, double or carousel reel, and the inspection unit "Rotary Inspect".

Continuous tandem cold mill (CTCM)
What defines the continuous tandem mill (CTCM) is a continuous entry section featuring a pay-off unit, welding machine, and strip accumulator. All this is necessary to ensure an unbroken production flow. Typical exit-side installations are also here the drum shear, as well as a tension reel and the inspection unit "Rotary Inspect".

Tandem cold mill (TCM)
Designs for high productionCrucial for large batch sizes is a continuous production flow. Further benefits for you are smooth production flow, low roll wear, high yield, and consistent product quality.
Especially in Europe, America, and Russia, there are many batch TCM in operation. That's no surprise, because this mill type offers considerable advantages and makes production planning flexible. To increase the yield, we have developed a number of trend-setting technical features in recent years. Included here is our threading assistance system TRC®. Using our engineering expertise, we offer you customized, efficient greenfield or revamp designs to ensure you get the most out of your mill. Needless to say, we can easily retrofit all our newly developed features.




Technology
X-Roll® laser welder
Fast, safe, and successful welding of challenging steel gradesPrecise, fast and reliable. The X-Roll® laser welder from SMS group for continuous production of difficult-to-weld steel grades.




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.
