Quick Roll-Changing in Steelstrip Production

27.02.2012
Siemens simplifies the production of steel strips: A new technology is making the exchange of pinch rolls in hot strip mills faster and more efficient.

The patented process reduces the time needed to replace pinch rolls in the down-coiling area by several hours, down to about ten minutes. Siemens developed an exchange cassette that makes it possible to quickly replace the entire unit with a new one.


The possibility of quick roll-changing reduces repair times, increases yield of the mill and boosts flexibility of changing between different products. As a consequence, it becomes easier for the producers of hot strips to reply to changing customer requirements.

Moreover, strips with consistent quality can be produced over a longer period of time. Cleaning and grinding of pinch rolls can now be done offline which improves strip quality and increases working safety.

Such hot-strip mills roll steel slabs up to 35 tons heavy into strips up to two meters wide and only one millimeter thick. The steel strip is still at temperatures of up to 600 degrees Celsius when coiling under tension between the pinch rolls. If the surface of a roll becomes damaged, the quality of the strip surface suffers.

In order to produce the highest quality steel, the rolls must be as freshly refurbished as possible. In order to prevent production stops caused by replace times up to 8 hours, these rolls need to be manually cleaned while production is under way.

By using the new cassette, the new pinch-roll quick-exchange unit from Siemens enables the roll replacement process in only ten minutes. All mounting connections, incl. the universal shaft release automatically. Then a bay crane is used to lift the cassette, with the two rolls, out of the pinch-roll unit and to put a freshly cleaned one in place.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
