Tandem cold mills

Cold rolling

High performance rolling for efficient production of advanced steel grades

From batch to fully continuous operation

Producing high quality strips in volumes between 0.9 and 2.5 million tons per year poses a huge 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. Optionally, it's possible to arrange them inline 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.

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 Rotary Inspect.

Continuous tandem cold mill (CTCM)

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 a drum shear, tension reel, and Rotary Inspect.

Designs for high production

Crucial 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 comes with considerable advantages for flexible production planning. To increase the yield of batch mills, 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.

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.
