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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Klima-Satellit: Mit robuster Lasertechnik Methan auf der Spur

Hitzewellen in der Arktis, längere Vegetationsperioden in Europa, schwere Überschwemmungen in Westafrika – mit Hilfe des deutsch-französischen Satelliten MERLIN wollen Wissenschaftler ab 2021 die Emissionen des Treibhausgases Methan auf der Erde erforschen. Möglich macht das ein neues robustes Lasersystem des Fraunhofer-Instituts für Lasertechnologie ILT in Aachen, das eine bisher unerreichte Messgenauigkeit erzielt.

Methan entsteht unter anderem bei Fäulnisprozessen. Es ist 25-mal wirksamer als das klimaschädliche Kohlendioxid, kommt in der Erdatmosphäre aber lange nicht...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
